The Challenge of recruiting a Military High Command
When hostilities began in April 1861 there were very few experienced military men available to fill the rapidly expanding positions of high commands in the Union and Confederate armies. Each side had to look very widely to find sufficient men with evidence of, or the potential for, military leadership.
Serving US Army officers, former US Army officers, Mexican-American War veterans, and military school graduates filled most of the higher positions as Colonels and as General Officers. Some foreign émigrés, many with military training, found positions. Many posts were also filled by prominent politicians, professional people, lawyers, or vocal civilians with little or no military training. Some of these had served in the pre-war Militia of the various States and other military groups, but few had authentic military experience and almost none had the experience of leading large forces. A few individuals had risen to prominence during the pre-war troubles in Kansas or Nebraska and elsewhere, or on the various frontiers, but their experience was on a scale soon to be dwarfed by the mass armies of the Civil War. Some gained prominence by raising regiments or even entire brigades for service and were rewarded with commands by their State governors.
With very few exceptions, the General Officers and even Colonels appointed at the start of the war by both sides were short of officers experienced in commanding and organising large forces beyond the size of a company. Those who had led a regiment were highly prized members of the military class. The shortage of experienced staff officers was as challenging as the dearth of field commanders. An underlying distrust of professional soldiers existed – suspecting “West-Pointers” especially to be bookbound and punctilious – while civilian soldiers were expected to compensate for their lack of training with resourcefulness, eagerness, and enterprise.
As the war progressed, especially after the scale of fighting and level of casualties accelerated from early 1862 onwards, it was increasingly possible for both armies to promote and appoint commanders with battlefield experience. Officers promoted to General grades were increasingly Colonels of regiments who had earned their elevation by merit or distinction and not only by seniority or public prominence. A few had served as staff officers to senior commanders. By 1863 the Generals in both armies were nearly all experienced soldiers and most of the incompetents and place-seekers had been weeded out. By 1865 both sides had built a proven corps of highly professional and battle-tested General Officers, but the process of their emergence differed.
What is a “General”?
In the Middle Ages, armies were generally led by kings, dukes, and other feudal lords, who commanded their own loyal retinues. These were grouped together into larger blocks for battle, largely in order of rank. These temporary assemblies were known as “battles”, the origin of the term battalion.
As armies evolved from feudal retinues into more professional organisations, the main military unit was the “Company” of soldiers, loyal to and commanded by their own Captain. The term “Captain” came from the Latin “caput“, meaning “head”. Captains recruited, maintained, and led their own companies and these gradually became permanent units. Captains were given commissions by their ruler or state with the authority to raise and command their own company. They were increasingly conferred their office by a political rather than a feudal authority. They held an “office” and were therefore “officers”. Their subordinate leaders did not necessarily have such a direct commission from the political power, so they eventually became known as non-commissioned officers.
Companies (or Squadrons) were bound together by duty, loyalty, or other inducements. They would operate within the same arm of service – infantry, cavalry, artillery, dragoons, etc. The Company Captain’s deputy would be termed a Lieutenant, taking the name from the French term “lieu tenant” or place-holding, denoting that the officer was standing in for their Captain. When a number of companies were collected together, the senior Captain would be named the Captain-Major, or “Big Captain”, and this was the origin of the grade of Major, who usually commanded a battalion of more than one company.
As military organisations expanded and became more systematic from the 15th Century onwards, a number of battalions or squadrons might be grouped together to march together in a “Column”. The Column would be led by the senior Major, who was named Colonel, a term derived from the word column or “colonello”. The Colonel’s second-in-command or deputy would therefore be the Lieutenant-Colonel, “holding the place of the Colonel”. The columns very quickly became more permanent groupings and groups of this size were described subsequently as a “Regiment”.
Regiments – and their constituent battalions and companies – became the building blocks of the large armies that formed during the 18th and 19th centuries. They would typically comprise soldiers of the same arm – infantry, cavalry, artillery, dragoons, etc. Their subordinate battalions and companies might operate separately at times but, in some armies, the regiment became the enduring repository of the heritage and traditions of a particular group of soldiers and their successors. The term regiment survived sometimes even after it had become an honorific or administrative designation for a defunct formation.
As armies became larger, and the proliferation of subordinate commanders made battlefield control unmanageable for a single army commander, a new evolution occurred between the 15th and 17th centuries. The base of units of companies, regiments, battalions, squadrons, or batteries, were grouped together into formations that operated independently under a field officer who reported directly to the army commander. The new concept described these temporary assemblies as “brigades” which might have single-arm or mixed-arms composition. Brigades were put together for a specific and temporary mission or for an entire campaign. The term brigade derived from French and Italian origins and gradually gained common usage in modern armies. The creation of brigades solved the problem of managing a proliferation of independent formations acting under their individual commanding officers. As armies grew in size, brigades might be collected as a Corps, or “a body” of men within a large army. A further invention by Napoleon Bonaparte subdivided a Corps into “Divisions” when necessary. A Division was typically a grouping of two or more brigades from one arm of service, but it would include all the supplementary and supporting formations and other arms to make it capable of independent operations.
Captains, Majors, and Colonels, therefore, emerged as the key officers in battlefield command of permanent or enduring military formations. They were usually connected indissolubly to their subordinate men and formations.
The higher and larger conglomerations of brigades, divisions, corps, and armies were more transient, comprising interchangeable mixtures of the building blocks of companies, battalions, squadrons, and regiments. They might exchange or add or subtract sub-units depending on the requirements of their mission. An officer commanding such a large and variable force needed to have a more “general” authority above and beyond their own “home” unit for which they had a specific commission. These “general officers” often commanded mixed arms forces of infantry and artillery, or cavalry, as well as their support echelons. Their responsibility was “general” so the term “General Officer” was applied to an officer appointed to lead a variable group of sub-units, whether of single or mixed arms and of varying size and composition. Moreover, a “General” officer could be transferred from group to group and assume varying commands as circumstances demanded. For example, a British officer might be commissioned to a named and specific regiment but once they became a General, their new command did not necessarily or automatically include that regiment.
By the 18th Century, increasingly large armies were made up more from massed civilians put in uniform for fixed periods of service rather than lifelong career soldiers. At the same time, the highest command in the field was transferred from Kings and Emperors to the appointed officers of their armies. These appointed officers would gradually evolve into professional soldiers because the maintenance of their forces, and their complex equipment, weapons, training, and supply became a year-round task, rather than a temporary duty for a single campaign. Therefore, the highest officer of an army had to be a “General”.
The original name of an army commander was the “General Major” – or the “Big General”. Over time, as the brigade became a key tactical formation, a “General of Brigade” would be appointed, usually from among its constituent units. These terms clearly evolved into Major-General and Brigadier-General. In due course, the overall commanding officer of an army would be known as “the General”. Where they needed a senior deputy from among the Major-Generals, the grade of Lieutenant-General eventually appeared in some armies.
The General could be switched from command to command and was entrusted with significant authority. By the 19th Century, the logistical and administrative demands of commanding such forces required the evolution of staff officers, and the “General Staff” came into being, initially formed from individual officers known and trusted by the General, but eventually made up of officers trained in various specialisms. In the Civil War, the term “Chief of Staff” was not in common usage but there are many occasions when the senior staff officer, sometimes known as the “Second in Command”, would deputise for the Commanding Officer rather than the senior officer in the chain of command.
Most names of military formations and officers’ grades or ranks tended to derive from the French language, as the French armies pioneered and innovated many of the features recognisable in the emerging professional armies of Europe. For example, platoon, company, battalion, regiment, brigade, division, corps, and even army, are all words based on French or earlier origins.
How does this apply to the American Civil War?
In the American Civil War, the original volunteer armies were recruited by companies that were banded together later to form regiments, frequently with elected officers when first mustered. Later on, regiments were recruited en bloc with a Colonel appointed to command by the particular State of origin.
The company was the ordinary soldier’s “home” or family, and it became the unit that managed an ordinary soldier’s practical and day-to-day existence. The company Captain was accessible, visible, and significant.
As there were usually ten companies in a volunteer infantry regiment, so the regiment’s Colonel was usually a more remote, but prominent figure. The regiment became the most important tactical unit for the deployment of infantry and cavalry in action. Usually fighting together as a single unit, regiments acquired a character and identity with which soldiers could build a strong, even lifelong, association. A well-led regiment, with a popular, competent, and respected Colonel, could be a powerful force on the battlefield.
Tactical or battlefield command was managed primarily at the brigade and division level and so the grade of Brigadier-General was extremely important for command at the battlefield level. Casualties were remarkably high. The operational command of divisions and corps was typically but not necessarily the domain of the Major-General.
The Union Evolution
The Union had an immense military machine, but they were bound to the command structure of the existing US Regular Army. The creation of new General officer grades would set precedents of grades and therefore salaries for the post-war army that they sought to avoid.
The Union armies managed for three years with just two grades of General officers, Brigadier-General and Major-General. These were explicitly differentiated as commissions in either the US Regular Army (permanent) or the US Volunteers (temporary). It was not until 1864, when pragmatic necessity compelled it, that the revival of the grade of Lieutenant-General was permitted by Congress to provide a third level. The grade of full General was not revived in the US Army until after the war.
President Abraham Lincoln became impatient with many of his initial pool of higher commanders. By the end of 1862, he was acting with increasing decisiveness to secure the dismissal of incompetents or, if that was impossible, to side-line them. The first batch of Union Generals included many self-publicists, failures, and outright embarrassments, some of whom survived far longer than was justified by their ability.
At the start of the war, there were many Regular Army officers serving in both staff departments and line commands whose age and seniority immediately conferred entitlement to a high command but whose capacity to cope with a new and dynamic style of warfare, active service in the field, and the management of large forces proved to be inadequate. Most of these had died, retired, or been side-lined by the end of 1863.
By mid-1863, a strong body of reliable, experienced, and suitable General Officers had emerged across the Union armies. These commanders had passed the test of fire and by late 1863 most of the important field commands were occupied by competent and, in some cases, highly talented commanders. Some peripheral or more administrative posts were still occupied by those who had failed on the main stage but whose service could not be easily terminated. Some senior officers could not be dismissed for reasons of political necessity but, whenever possible, these were shifted to less critical positions. Nevertheless, a few early appointees remained in high command far longer than was desirable.
The list of the highest Union commanders in 1865 shows little resemblance to that of 1861 and early 1862. Comparatively few of the original senior commanders of 1861 and 1862 still remained in important field commands by 1865, having been supplanted by more dynamic commanders who had advanced through merit and experience.
The Confederate Evolution
The Confederates had the opportunity to create a brand-new command and grade structure for the Army they had to create almost from scratch. The individual States appointed their own officers and generals, but almost immediately the Confederacy appointed senior general officers to command formations comprising units from several States. The novel grade of General was invented early in 1861 and after just over a year the grade of Lieutenant-General was also authorised, providing grades that matched the different levels of authority of their immense forces. Major-Generals and Brigadier-Generals were also appointed immediately, but the Confederate approach was to start fairly early with full Generals and Brigadier-Generals and then to fill in the gaps more gradually with Major-Generals in 1861 and Lieutenant-Generals in 1862.
Broadly speaking, and with some egregious exceptions, the Confederates were rather more fortunate than the Union in their selection of commanding Generals in the early part of the war. Some outstanding commanders emerged at all levels early in the conflict and this contributed to some significant successes during 1862 and 1863. There were also some poor appointments where officers had to be removed or reassigned. The list of the highest-ranking Generals changed little through the war but many early and older and lesser-known Brigadier-Generals and Major-Generals did fall by the wayside during 1861 and 1862.
Confederate President Jefferson Davis showed great loyalty to his earliest appointees and as a former soldier and Secretary of War, he was also very alert to the sensitivities and protocols of seniority. While a few highly talented exceptions had broken into the highest echelons of the Confederate army through proven ability by the end of the war, the list of Confederate Generals holding the very highest grades and commands changed remarkably little between early 1862 and 1865. However, the high rate of battle casualties, especially by the middle of 1864, caused severe erosion in the Confederate high command. Confederate Generals had to be elevated increasingly to succeed casualties rather than to replace failures. The conventional route of succession through seniority and succession that was sacrosanct for most of the war had to give way by the middle of 1864 to necessity and the recognition of some talented but less senior officers whose merits were undeniable.
How many General Officers?
During the Civil War, there were between 554 and 564 Union Generals of substantive grade, and between 398 and 401 Confederate Generals of substantive grade. Substantive officers were properly appointed, confirmed, accepted the appointment, and served actively as General Officers.
It is believed that 583 actual, substantive Generals of various grades or levels were appointed by United States President Abraham Lincoln and confirmed by the Senate for the Union Army and 425 actual, substantive Generals of various grades or levels were duly appointed by Confederate States President Jefferson Davis and confirmed by the Senate for the Confederate Army during the course of the American Civil War. These numbers could properly be reduced by about 25 names each to account for cancelled appointments and unconfirmed nominations. For various reasons, there are disparities concerning the number of Militia Generals and many anomalous cases who might be counted or recognised as Generals or where evidence is unforthcoming.
A General Officer of the Union Army, whether of the United States Regular Army or the United States Volunteers, and whether of full or Brevet grade, could legally be promoted to the grade of a General Officer only if appointed by the President of the United States and confirmed by the United States Senate. Field promotions, the exercise of command duties, or Brevet rank promotions alone were insufficient to qualify an officer as a substantive General Officer until duly appointed and confirmed.
A General Officer in the Confederate Army could be appointed only by the President of the Confederate States and confirmed by the Confederate States Senate; an exception being those officers holding a grade on the date of enactment of the first Confederate law on the subject of appointment of General Officers, 21st May 1861, were permitted to keep those ranks. Late in the war, these practices had to be loosened in two significant ways. Firstly, after the Trans-Mississippi region was almost completely cut off after the fall of Vicksburg and General Edmund Kirby Smith was given interim plenipotentiary powers as he could not obtain proper confirmation of promotions by the President or Senate. Secondly, a number of “Special” promotions were permitted where a General was appointed to a higher grade on an interim basis only, usually to cover the extended absence of another commander through illness or wounds. Most of these promotions were confirmed permanently but some expired and the officer reverted to their substantive rank.
The Union Army was supported in active field command by a number of State Militia Generals who were not taken into the United States Volunteers with a state regiment nor recruited to Federal service. The Union Army also had several officers assigned to command or temporarily placed in command of units normally assigned to a General Officer but who did not receive full-rank appointments commensurate with their command.
A number of Confederate officers exercised high command as commanders of Militia or State Troops but were never formally appointed as Confederate Generals. There were many officers assigned to a command or temporarily placed in command of units normally assigned to a General Officer but who did not receive full-rank appointments. As many as 159 uncertain cases and 226 Militia officers have been identified as Confederate Generals of some sort. Ten officers who were assigned to duty by General Edmund Kirby Smith in the Trans-Mississippi Department but unconfirmed by Congress after communications were severed are among these uncertain cases.
There were 1,367 Union officers who were not promoted to a substantive General rank but were awarded Brevet General Officer rank (or, to within 10 of this number). Most Brevet ranks were awarded posthumously or to rank from dates near the end of the war and many of them were not confirmed until 1866 or later. At the time of the Civil War, these Brevet appointments were honorary titles and had little effect on command positions or status, especially since most of the awards were not confirmed until months or even years after the war was over, regardless of the date from which the awarded Brevet grade was to rank. In some respects, they might be seen as an early equivalent of medals for valour, good conduct, or distinguished service that were created later.
The Confederate Army never introduced a system of awarding Brevet ranks although a similar form of recognition would undoubtedly have been introduced had the Confederacy achieved its goal of independence.

Regulars and Volunteers
When hostilities threatened to begin in 1861, there was a need to mobilise high numbers of armed men to create armies and a navy large enough for the task. The United States adopted a practice that had been effective in its previous wars by raising volunteers for limited term service primarily through the various states. Rather than increasing the size of the permanent US Regular Army, it was decided to keep it apart as a distinct core of permanent professional soldiers and to provide numbers through temporary volunteer forces.
The Regular Army was not expected to provide a trained cadre from which officers and trained non-commissioned officers were drawn to command units of US Volunteers. It was to remain as unchanged as possible, supplemented by a much larger temporary force, engaged for specified periods of temporary service. This temporary force was designated the US Volunteers. Even when the desperate need for men eventually forced the adoption of the draft and compulsory conscription, the force retained the name of US Volunteers. The US Volunteers ultimately expanded to an unprecedented size. The Regular Army expanded to a much lesser extent.
It was envisaged that the permanent Regular Army would maintain a modest size and structure and retain most of its officers and enlisted men. Some would operate on the frontier against the Native Americans or in garrisons and fixed fortifications but most of these were fairly replaced by volunteers. Most Regular Army units were rapidly redeployed to serve with the armies. In time, several new Regular Army regiments were raised for field service with the fighting forces.
Almost all units of the US Volunteers, with a few interesting exceptions, were recruited on a state-by-state basis, with each State fulfilling a stipulated quota of men to serve under officers appointed by the State. Each State raising units for the US Volunteers was expected to identify and appoint commanders for its units. Suitable candidates with the ability to learn and to lead were sought from all walks of civilian and professional and political life but those with military training or experience were at a premium. While military experience was usually viewed as an advantage, formal military training provided by the Regular Army or West Point was thought by some to inculcate a rigid and rule-bound approach unsuitable to the leadership of independent-minded Americans. Nevertheless, any form of military training and expertise was highly prized.
By necessity, men with little or no military credentials whatsoever took command as Colonels of many US Volunteers regiments, trusting that their civilian leadership qualities would suffice to supplement eager hands-on learning in the field. Even some Brigadier-Generals and Major-Generals received commands without obvious military credentials. Company officers rarely had military expertise and the majority learned on the job. Wherever possible, field grade officers of the regular Army (Colonel, Lieutenant-Colonel and Major) were allocated to command brigades, divisions, and higher formations. Junior officers (Captains and Lieutenants) were greatly prized to train and command Volunteer regiments.
Officers and General Officers could be appointed to a grade either in the United States Army (USA) or the United States Volunteers (USV) or both concurrently. A grade in the US Army was a permanent promotion in the Regular Army that would remain in force after the end of hostilities. As such, General Officer grades in the US Regular Army ranks were authorised very sparingly and within strictly regulated limits. At first, only those commanders who would be expected to remain in service when hostilities ended and the armies contracted back to pre-war proportions, received such appointments. Eventually, however, men whose Regular Army commitment was not so clear-cut were increasingly appointed.
Seniority
Seniority for General Officers was determined by the date of rank stated in the Senate’s confirmation resolution, which could be a date earlier or occasionally later than the confirmation date. Otherwise, rank would be determined by the order of names on the lists of officers confirmed in the same resolution made on the same date to rank from the same date. Where uncertainty arose about seniority, rank in the USA was deemed higher than the equivalent rank in the USV. For example, a Brigadier-General in the US Regular Army outranked a Brigadier-General in the US Volunteers. However, a Major-General in the US Volunteers outranked a Brigadier-General in the US Army, although the circumstances where such a command was asserted were uncommon. The US Army was usually punctilious in ensuring that those US Volunteers who were promoted to senior commands also received promotions both in the USV and the USA appropriate to their status and needful authority. The use of Brevet ranks was a helpful expedient on occasion. In extreme cases of uncertainty, if seniority was otherwise the same, age could be a determining factor but may never have been required.
Prior to the Civil War, the Army itself had no professional personnel system in the modern sense. Traditionally, most officers came into the service from the US Military Academy at the lowest rank and received promotions on the basis of seniority. Officers commissioned without a formal training learned in service.
As a result of the seniority rules, the General Officers, chief staff officers, and full colonels of the small pre-Civil War Regular Army were almost all were of advanced age. The General-in-Chief, Major-General USA Winfield Scott, ranked from 25 June 1841 and was first commissioned in 1808. Brigadier-General USA John Ellis Wool ranked from 25 June 1841 and was first commissioned in 1812. Brigadier-General USA David Emanuel Twiggs ranked from 30 June 1846 and was first commissioned in 1812. Brigadier-General USA William Selby Harney was the “youngster”, ranking from 14 June 1858 although first commissioned in 1818. Brigadier-General USA and Quartermaster-General Joseph Eggleston Johnston was promoted to the staff on 28 June 1860 but was first commissioned in 1829.
Among the top field officers, 11 of the 19 colonels of the line had fought in the War of 1812 as commissioned officers. Thirteen of these individuals stayed with the Union and during the Civil War five of them died, seven retired, and one was relieved of command. Not one of these officers was still on active duty by the end of hostilities. Of the four who joined the Confederacy, three were appointed to the grade of General in 1861; one died, one was killed in action, but the two others were still serving at the end of the war. This indicates that the seniority rule persisted among the Confederates as much as for the Union and they were also forced to find novel solutions to circumvent it.
The ineffectiveness of an army based on advancement by seniority was quickly exposed during the war, and a formal retirement system was deemed essential. In 1861, Congress provided for compulsory retirement for incapacity. In 1862 and again in 1870 measures were introduced to permit an officer to retire either voluntarily or compulsorily at the President’s discretion after thirty years’ service. It was not until 1882 that legislation made retirement compulsory at the age of sixty-four. Beginning in 1890, promotions for all officers below the rank of Major were by examination, to ensure a minimum level of professional competence.
Regulars in the Volunteers
The US Volunteers force expanded rapidly, creating opportunities for men who had commanded no more than a company or a militia unit – perhaps even in the rather distant past – to be appointed as colonels of regiments. There was stiff competition to secure the most promising talent from the pool of current and retired officers to command new Volunteer units. Anyone with military training or experience was prized. Many Regular Army officers were induced to retire in order to take a higher command and more rapid promotion in the US Volunteers. Others retained their Regular Army grade and were appointed simultaneously to serve in the US Volunteers. State origin often influenced the appointment of officers – and also directed the choices of the officers themselves – but it was not essential to hail from a particular State to receive a commission in the US Volunteers.
A dilemma arose for all Regular Army officers. Should they retain their secure and permanent regular commission or resign to seek a temporary but more lucrative and senior commission in the US Volunteers at a much higher rank? The US Regular Army was static if not stagnant and seniority was the primary factor in advancement. Even though several new regiments were formed during the war, many frustrated or ambitious officers responded to the appeal to join the US Volunteers, alongside many retired officers.
Grade in the US Volunteers was always considered a temporary appointment and it did not confer continuing rank or position when or if an officer rejoined the Regular Army after the end of hostilities. Many Regular Army officers did not resign their Regular commission and took Volunteer commissions concurrently, effectively receiving a leave of absence from their Regular unit. If they progressed through the Volunteer grades, their Regular Army grade sometimes had to advance to ensure that they could continue to exercise authority or seniority above subordinates in both hierarchies.
Almost immediately, the US Volunteers expanded to a point where regiments had to be formed into brigades, then into divisions, and finally into corps and entire armies. While the States appointed the colonels of their US Volunteers’ regiments, their commission permitted them only to command their state’s forces. The jurisdiction of Generals exceeded the limits of any particular state, and their commands usually comprised units deriving from more than one state, and not only the state of their original commission. Therefore, General Officers commanding brigades or higher commands had to be appointed and confirmed by the US Congress. When these were serving Regular Army officers they were frequently transferred to new regiments or staff bureaux within the Regular Army but were effectively absent on war duty. Vacancies occurred throughout the Regular Army which were either filled by the remaining officers deputising for the absentees or left void, especially in the Artillery.
Evolution of the Regiments of the US Regular Army from 1815 to 1869
Twenty-five regiments of infantry were approved by Act of Congress on 26 June 1812. These were raised to prosecute the War of 1812 against Great Britain. Two new Artillery regiments were created to supplement the one existing single regiment.
After the end of the War of 1812, an act of Congress dated 3 March 1815, authorised a reduction of the Army to eight infantry regiments, one rifle regiment, a Corps of Artillery, and a Light Artillery regiment. The infantry was reformed from the 46 existing regiments and the cavalry was eliminated. This consolidation was done with no regard for the traditions of the existing regiments. The old Infantry regiments which happened to be closest together were consolidated into the new regiments and the numbers assigned to the new regiments were based on the seniority of the colonels commanding them and not on their prior designations. At the end of the War of 1812 the army was reduced in size and the Corps of Artillery retained 32 companies organised in eight battalions. The Light Artillery Regiment was unchanged. The first seven numbered infantry regiments were organised in 1815 and an eighth was added in 1838.
On 21 March 1821, the Light Artillery Regiment, Ordnance, and the Corps of Artillery were merged. At first each regiment had nine companies each under a Captain. A tenth captain performed ordnance duties. One company in each regiment was nominated as a Light Battery but it was only in name until 1836. In 1832, the Ordnance was separated from the Artillery and the reorganisation was completed on 5 July 1838. This last named Act added a tenth Company K, and the Act of 3 March 1847, added Companies L and M to each Artillery regiment to provide each of them with twelve Companies. A Major was added to each of the four US Artillery regiments by the Act of 11 February 1847 so they could operate at least hypothetically in battalions.
The first regiment of mounted troops to be established was the US Dragoons on 2 March 1833. This force was expanded in May 1836 to become the 1st Dragoons and 2nd Dragoons. As the frontier extended westwards, the demand for mounted troops grew so that on 27 May 1846 the Mounted Rifles regiment was established. These three regiments were later renumbered as 1st, 2nd, and 3rd Cavalry in the reorganisation of 3 August 1861.
Ten new regiments were authorised by the Act of 11 February 1847 for one year’s service in the Mexican War. These included nine infantry regiments and a regiment of Voltigeurs and Rifles. By 26 August 1848, their officers and soldiers were discharged and the regiments disbanded. Some of these officers transferred to the Regular Army but the majority left the service, These regiments had no lineage connection with earlier or later Regiments.
The 9th and 10th Infantry regiments were organised in 1855 as part of a major reorganisation. These were joined by two new regiments of cavalry, originally designated the 1st Cavalry and 2nd Cavalry, which were re-designated in 1861 as the 4th and 5th Cavalry as part of the reorganisation of 3 August 1861.
On 1 January 1861, the US Regular Army was organised primarily for operations on the western frontier. There were 198 companies formed into 10 Regiments of Infantry, 4 Regiments of Artillery, 2 Regiments of Dragoons, 1 Regiment of Mounted Rifles, and 2 Regiments of Cavalry. The majority of field forces were deployed along the western frontier and in the new territories. Garrisons were also located in the primary east coast ports where a new generation of coastal fortifications was under construction. Of the 198 available companies or batteries, 183 were stationed at 79 different posts west of the Mississippi. The other 15 companies, mostly artillery, were allocated to coastal fortifications, 23 arsenals, and at posts on the Canadian border.
There were 1,098 Officers and 15,304 Enlisted Men of whom 727 Officers and 13,930 Enlisted Men were present for duty. Of 1,108 Regular Army officers serving on 1 January 1861, 270 resigned to join the Confederacy. Only a few hundred out of 15,135 enlisted men left the ranks.
The six Military Departments reported the following numbers available for duty after 15 January 1861:
East 3,894, West 3,585, Utah 685, California 3,382, New Mexico 2,624, and Texas 2,258.
The Department of the East manned the eastern coast fortifications with 18 artillery companies and one company of engineers but no infantry or cavalry. None were stationed in the vicinity of Washington, DC. The Department of Utah had three companies of dragoons, three companies of artillery, and four companies of infantry. Thirteen companies of infantry and two companies of dragoons were in the Department of New Mexico. One regiment of infantry was in the Department of Texas. There were small forces also in the Department of California and the Department of Oregon.
Army administration was managed by a system of bureaux. These bureaux answered directly to the War Department and were not subject to the direct orders of the General-in-Chief. The staff departments covered these primary areas of responsibility: Quartermaster, Medical, Ordnance, Adjutant-General, Subsistence, Paymaster, Engineers, Inspector-General, Topographical Engineers (discontinued in 1863), and Judge Advocate-General.
US Artillery Regiments were reorganised to operate independently by Battery by March 1861. Companies were renamed as batteries and operated independently as attachments to infantry and cavalry commands. The regimental structure persisted as an administrative function only. In practice the field officers of the Regular artillery were all given volunteer rank to command infantry brigades and increasingly higher commands.
On 14 May 1861, eleven new Regiments of US Infantry were organised. Unlike the traditional structure of ten companies, these new regiments comprised three battalions of eight companies each. Infantry Regiments of US Volunteers raised for the American Civilo War, however, generally followed the traditional pattern of ten companies. At the same time, the 5th Artillery Regiment was formed.
On 3 August 1861, the cavalry was reorganised to homogenise their titles and roles. The names of the 1st Dragoons, 2nd Dragoons, and Mounted Rifles were dropped and they were renamed the 1st, 2nd, and 3rd Cavalry. The existing 1st Cavalry and 2nd Cavalry were renumbered as the 4th Cavalry and 5th Cavalry to acknowledge the seniority of their forbears. The new 6th Cavalry was also established at this time.
On 1 May 1865, there were 1,034,064 volunteers in the Union Army. By the middle of November 1865, over 800,000 of them had been paid, mustered out, and transported to their home states by the Quartermaster Corps. A year later there were only 11,043 volunteers left in service, most of whom were US Colored Troops, of whom almost all were mustered out by late October 1867.
On 28 July 1866, an Act of Congress voted a reduced establishment of 54,302 officers and enlisted men. The nine Infantry regiments formed with three battalions each that were raised in May 1861 (11th to 19th Infantry) were reorganised. The battalions were reorganised as regiments, each battalion receiving two additional companies to revert to traditional ten company lines. The 1st Battalion of the regiment usually retained the numerical designation while the other two battalions formed the basis of eighteen new regiments. The new Infantry regiments were designated as the 20th to 37th Infantry. The same Act created a further six new regiments specifically for enlisted black men: these were the 9th and 10th Cavalry and the 38th, 39th, 40th, and 41st Infantry Regiments. This signified the first proactive inclusion of black units in the US Regular army, although commissioned officers of black units were predominately white. Many black soldiers had served in the artillery but there was no provision for segregated black artillery unit after the war. The five regiments of Artillery continued without reduction. A third Major was assigned to each Artillery Regiment by the Act of 28 July 1866. This latter change permitted their twelve artillery batteries to be organised into three recognisable battalions.
The 42nd, 43rd, 44th, and 45th Infantry regiments were raised temporarily for service in occupation and reconstruction of the South from 1866 to 1869. A provision in the 1866 act had established four infantry regiments and two cavalry regiments made up of African Americans. The number of these segregated infantry regiments was reduced to two in 1869 but the cavalry regiments were not reduced.
After the end of hostilities, Lieutenant-General Ulysses Simpson Grant wanted to increase the size of the US Regular Army to 80,000 men, but neither Secretary of War Edwin McMasters Stanton nor the US Congress would agree to the measure. Actual strength reached about 57,000 on 30 September 1867, and this was the peak strength of the Army until the Spanish-American War of 1898.
On 3 March 1869, Congress reduced the number of infantry regiments from 45 to 25. The four regiments of black infantry were reduced to wo. The authorised strength was set at 45,000. In 1876, regimental organisation was adjusted to reduce the total authorised force to 27,442 men.
The Confederate States Army (ACSA) and the Provisional Army of the Confederate States (PACS)
When the Confederate Congress established its War Department on 21 February 1861, the structure and organisation of the Confederate States Army were inevitably based on the structure and customs of the US Army.
The Confederate Army comprised three elements; the Army of the Confederate States of America (ACSA), which was intended to become the permanent regular army after the achievement of sovereignty, the Provisional Army of the Confederate States (PACS), which was a “Volunteer” Army to be disbanded after hostilities; and also, the Militias and Forces of the several States.
The Confederate Army ultimately had four grades or levels of General Officers: General, Lieutenant-General, Major-General and Brigadier-General. The Regular Army of the Confederate States of America (ACSA) did not progress far beyond the planning stage.
The Provisional Army of the Confederate States (PACS) was the effective force organised and so PACS and ACSA ranks were broadly identical operationally.
Many former US Army officers who joined the Confederacy were given their initial commission in the ACSA. The majority of these dated nominally and retrospectively from 16 March 1861 and were usually set at one grade above the grade in the US Army just vacated. Nearly all of the received a subsequent commission in the PACS and their ACSA commission was a temporary assignment to secure their services. Many officers also or alternatively gained a commission in the Militia, State Troops, or Provisional Army of various states. This happened particularly in the states that joined the Confederacy later in time, especially Virginia. These were sometimes long-term but usually turned out to be interim arrangements until they could be assigned to a command in the Confederate service. By mid-1861, the majority of these interim and ad hoc arrangements had been converted to PACS commissions.
The role of the United States Military Academy
The United States Military Academy was established at West Point, New York in 1802 to train the new nation’s young men in advanced military and engineering skills and prepare the future leaders of the United States Army. The Academy produced 445 Civil War generals – 294 for the Union and 151 for the Confederacy. Of graduates who were still alive at the start of the war, 105 were killed and 151 had been wounded – 25% of the total. A West Point graduate commanded one or both armies in every one of the 60 major battles of the war.
At the outbreak of the Civil War, 296 US Regular Army officers of various grades resigned. Of these, 239 joined the Confederate Army in 1861 and a further 31 joined after 1861. Of these 270 Confederate officers from the US Army, 184 were United States Military Academy graduates. The other 809 active officers in the US Army, 640 of whom were West Point graduates, remained with the Union. Approximately 900 West Point graduates were in civilian life at the beginning of the war, and of these 114 returned to serve in the Union Army and 99 joined the Confederate Army.
In total, there were 283 Confederate and 754 Union “West Pointers” but professional military training did not necessarily confer high command. Loudly voiced prejudice was often voiced against West Pointers, especially in the North. This was partially justified by the small size, limited field experience and overly bureaucratic nature of the pre-war army, but accusations of excessive punctiliousness or even incompetence among them were largely unfounded. The Confederates were more energetic in finding and promoting officers with West Point training.
The first cadets of the United States Military Academy graduated in 1805; 52 cadets graduated in the first ten years, of whom only three served in the Civil War.
Graduates of Military Institutes
Norwich University in Northfield, Vermont furnished more officers to the war than any other military school except the United States Military Academy (West Point) and the Virginia Military Institute. The school contributed 523 officers to the Union Army and 34 to the Confederate Army. Norwich was the only military college in the Union states, other than West Point, with a sizable number of military-trained alumni. Of the 1,902 men who had attended the Virginia Military Institute in Lexington, Virginia, 1,781 fought for the Confederacy. One-third of the field officers of Virginia regiments in 1861 were VMI graduates. The Citadel Military College of South Carolina provided at least six General Officers to the Confederate Army as well as 49 field-grade officers (Colonel, Lieutenant-Colonel, Major) and 120 company-grade officers.
Militia Generals
Most states had Militias in place since Revolutionary War times consistent with the US Militia Act of 1792. They went by varied names such as State “Militia” or “Armies”, “State Troops”, “State Guard” or “Guard” and most were activated and expanded when the Civil War began. These units were commanded by “Militia Generals” in order to defend their particular state and rarely left home soil. State Militias used the General Officer ranks of Brigadier-General and Major-General; the commanding General of the Militia in a State was usually a Major-General. The regulations in the Act of 1792 provided for Militias into two classes based on age. Class one was to include men from 21 to 30 years old, and class two would include men from 18 to 20 years as well as from 31 to 45 years old.
At the beginning of the Civil War, the Union Army incorporated most State Militia units from the States adhering to the Union for federal service. Many Generals of these units did not receive US appointments and remained appointments with authority only within their state. Some states retained or recruited Militia units for local defence, but Generals rarely saw active service as State Militia units remaining under State control did not leave their States for service elsewhere.
The Confederate States Army followed a similar pattern with respect to incorporating volunteer Militias, but certain States retained a significant number of Militia units for local defence. Some State-appointed Generals saw significant active service, usually under the command of Confederate States Army commanders. On a few occasions, they were the only forces available to oppose Union operations. State units fought in Texas, Missouri, Virginia, Mississippi, Georgia, and South Carolina.
There was an acute shortage of weapons, uniforms, and trained officers in the Militia. Among the available States’ Militia regiments, there were very uneven standards of training, with none being battle-ready. Typical Militia training at the time amounted at best to parade-ground drill. Militia units were raised in local communities and rarely met above company level; they never drilled together in formations as large as regiments.
Some states retained or recruited Militia units for local defence, but Militia Generals rarely saw active service as State Militia units remaining under State control did not leave their States for service elsewhere. Notable examples of Militia and local defence forces being on active service occurred in Pennsylvania, Maryland, Kentucky, Missouri, Kansas, Indiana, and Ohio.
In the West, some State and Territorial Militias were more active forces and acted in defence of settlers. California had many active Militia companies at the beginning of the war and these increased in number throughout the conflict. California also provided the largest contingent of volunteers from west of the Rocky Mountains, (eight regiments and two battalions of infantry, two regiments, and a battalion of cavalry). It also provided most of the men for a volunteer infantry regiment from the Washington Territory. Oregon raised an infantry regiment and a cavalry regiment. Colorado Territory Militias were organised to resist Confederate invasion and civil disorder provoked by secessionists, Copperheads, Mormons, and Native Americans. Colorado Volunteers participated in the repulse of the Confederate invasion of New Mexico Territory and later instigated the Colorado War with the Plains Indians. California Volunteers of the California Column travelled east across the southern deserts to drive the Confederates out of southern Arizona, New Mexico, and the part of west Texas around El Paso. They continued to fight the Navajo and Apache until 1866. They also guarded the Overland Trail, kept the Mormons under observation by the establishment of Fort Douglas in Salt Lake City, and fought a campaign against the Shoshone. California, Oregon, and Washington Territorial Volunteers tried to protect the settlers in Nevada, Oregon, and the Idaho Territory and fought against the Goshute, Paiute, Ute, and hostile Snake Indians in the Snake War from 1864 to 1866. California Volunteer forces fought the Bald Hills War in the north-western forests until 1864 and also the Owens Valley Indian War during 1862 and 1863.
“Civilian” and “Political” Generals
Popular sentiment for “self-made” Generals proven in action and the influence of political figures secured many high commands for unqualified civilians. Pre-war Governors, Senators, Congressmen, Mayors, and other holders of high offices were appointed to high commands early in the war on both sides, with the assumption that leadership and position in civilian life were good indicators of their military potential. Some proved to be very able leaders and succeeded spectacularly despite their inexperience; while others proved to be disasters or embarrassments. Both armies encountered difficulty in removing influential political and public figures who had proved unsuited to the task and some who were relieved of command subsequently became political thorns in the side of the government.
