Careers of American Civil War Generals in the US Regular Army

Careers of American Civil War Generals in the US Regular Army

This page lists in chronological order the progression of the careers of American Civil War Generals who had some service in the US Regular Army, whether short or long. It begins in 1805 and ends in 1896. The list includes only those who achieved at some point the grace of Brigadier-General or Major-General or Lieutenant-General or General in the US Regular Army (USA) or US Volunteers (USV) or Confederate Army (ACSA or PACS).

The primary aim is to indicate where officers served and progressed by regiment or staff bureau over time, and at what grade. Once officers reach the grade of Brigadier-General or higher in the Regular Army, or left the US Army service, their career is no longer recorded but subsequent key progressions are noted.

This list helps to show the parallel progression by seniority or merit of officers who became prominent in the American Civil War.

Between the records of individual career progression, I have summarised the main occasions of expansion and reduction of the number of regiments in the US Regular Army as this significantly affected opportunities for advancement. The other major factor for progression, after seniority, was active service; for example, substantial changes occurred during the Seminole Wars, the Mexican War, and the campaigns of the Civil War Itself.

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.

The US Regular Army on 1 January 1861

On 1 January 1861, 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 US Regular Army was organised primarily for operations on the western frontier. 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, Corps of Engineers, Inspector-General, Topographical Engineers (discontinued in 1863), and Judge Advocate-General.

The US Regular Army on 1 May 1865 and onwards

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, of whom most 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 black enlisted 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.

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 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. They were numbered 11^th to 19^th Infantry with their battalions designated as 1^st, 2^nd, and 3^rd within each Regiment. This reorganisation permitted field officers of the existing Infantry Regiments to be made available to command larger formations in the expanding US Volunteers, usually with a grade of Brigadier-General or Major-General. Junior officers were also more available to command US Volunteers regiments as Colonel or even as General Officers. Infantry Regiments of US Volunteers raised for the American Civil War generally followed the traditional pattern of ten companies.

The 5th Artillery Regiment was formed.

The Artillery Regiments were reorganised to operate independently by Battery. Companies were renamed as batteries and operated independently as attachments to infantry and cavalry commands. The regimental structure persisted as a minimal administrative function only. Therefore, the field officers of the Regular artillery were available to command at higher grades in the US Volunteers.

On 28 July 1866, an Act of Congress voted a reduced establishment of 54,302 officers and enlisted men. The nine Infantry regiments that were raised in May 1861 with three battalions each (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. No provision was made for black artillery units and the five regiments of Artillery continued without reduction. A third Major was assigned to each Artillery Regiment by the Act of 28 July 1866 to permit the 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.

The 7^th, 8^th, 9^th and 10^th Cavalry Regiments were also authorised.
