Reading the Day-by-Day Chronology
This Chronology has been compiled primarily to support a study of the evolution of the higher military organisations and officers of the American Civil War.
The Chronology records each major military reorganisation, and changes of command in the context of the wider events of the war.
It also lists the promotions and other important changes of status involving General Officers of the Confederate and Union armies.
The Timeline begins on January 1st 1861 and ends on August 31st 1865, with brief summaries for 1860 and September to December 1865.
Every day of the American Civil War is individually listed, to the following format.
Events of the Day
The first line lists the Month, Date, Year and Day:
May 3 1862 Saturday
Significant Events and Incidents are listed:
Ongoing Major Campaigns are listed next
Peninsula Campaign – Siege of Yorktown
Confederate Evacuation of New Mexico
Then, Events are listed by Location, in this order:
Events or actions in overseas or maritime locations
Events or actions in the USA but not specific to a state or territory
Events or actions in the CSA but not specific to a state or territory
Events or actions in individual states or territories in alphabetical order
Arkansas. Incident at Batesville.
Georgia. Incidents at Lookout Creek and Watkins Ferry.
Virginia. Martial law was declared in southwestern Virginia.
Virginia. Confederate General Joseph Eggleston Johnston ordered Major-General John Bankhead Magruder to abandon the defences of Yorktown and to fall back towards new defences being built around Richmond… etc.
Note: The term “incident” is used as a very broad term to refer to a range of events; it does not necessarily indicate or imply a military clash of arms. It may refer to a departure, arrival, encounter, occupation, reconnaissance, political or civil incident, or other event or noted circumstance. “Incidents”, especially if they are military engagements, may be described in more detail within the longer text that follows, but more frequently they are not elaborated further. They can be considered of minor importance to the general conduct of the war, albeit of local interest. The same incident may be mentioned more than once under different names or variant spellings of names, or by both a local and by a more general name. Expeditions and Reconnaissances may be described by their destination, or their departure point or by waymarks – or even all three – and may be duplicated within a state or across more than one state.
Then, there may follow a more detailed account of battles, raids, operations, expeditions, reconnaissances, etc. These longer passages may include major strategic or political events and decisions, military reorganisations,or plans and decisions, and important interactions between or involving individuals. Wherever possible, the Union or Confederate allegiance of individuals, and their full name, is noted the first time they are mentioned on a particular day. Subsequently, they would typically only be mentioned by surname on the same day
Events and incidents outside the specific area and scope of the Civil War (e.g. military operations against Native Americans and naval operations) are included in many cases to reflect the wider context of events across the continent.

Union Organisation and Confederate Organisation
This Resource has been compiled primarily to support study of the evolution of Higher Military Organisations of the American Civil War. The Chronology allows major military reorganisations and changes of command to be identified sequentially. To achieve that aim, each Day’s Chronology includes a Structural Chart of each Military Division, Department, District, Sub-District, Army and Army Corps, and their equivalents.
Commanders are listed against each command, but not their current rank. In many cases, there were delays between the date of appointment and the date of “arrival” to command. Arrival can mean either an arrival in person to assume command or a date on which an appointment comes into force where a commander is already present or is serving in an interim or temporary capacity and is appointed permanently. Where a commander is appointed but never arrives to assume a significant command their name is not listed but this will be noted in the Timeline. Where there is a temporary or interim commander their name is listed until the substantive commander “arrives” to command. Where (as in the case of a fatality or incapacitation) the command changes on a day, the replacement commander is listed.
This format makes it possible to follow the changing scope and size of the military organisations of the Union and the Confederacy, and also to identify quickly the status and hierarchical relationships of individuals within the structure. It also permits reference to the status of the command structure on any specific date.
The Organisation Table is structured to demonstrate the hierarchy of command. Where commands are subordinated, they are indented below their parent command.
The Political Hierarchy, with specific responsibility for military affairs, for example:
Commander in Chief: President Abraham Lincoln
Vice-President: Hannibal Hamlin
Secretary of War: Edwin McMasters Stanton
Secretary of the Navy: Gideon Welles
For the Union only, the US Navy structure and hierarchy, for example:
North Atlantic Blockading Squadron USN: Flag Officer Louis Malesherbes Goldsborough USN
South Atlantic Blockading Squadron USN: Flag Officer Samuel Francis Du Pont USN
West Gulf Blockading Squadron USN: Rear Admiral David Glasgow Farragut USN
The Senior Commanding General:
General–in-Chief: Henry Wager Halleck
The Highest Level of Territorial Command is a Military Division, where these exist: usually to coordinate the operations of more than one Department at a grand strategic level:
- Military Division of the Mississippi: Ulysses Simpson Grant
The Highest Level of Territorial Command is usually a Department; these exist to direct and organise operations at a strategic level:
- Department of the Cumberland: George Henry Thomas
Within a Department, there may be one or more subordinate Districts; these exist to direct and organise operations at a regional level:
- District of Nashville: Lovell Harrison Rousseau
Within a District, there may be one or more subordinate Sub-Districts; these exist to direct and organise operations at a specific post or local level:
- Sub-District of Columbus: Isaac Ferdinand Quinby
Field forces of a larger size – or with strategic significance – are generally referred to as Armies; typically, but not necessarily, they are subordinated to a Department and commanded by the Department commander:
- Army of the Cumberland: George Henry Thomas
Within an Army or a Department, there may be one or more permanently constituted parts of an Army or other groups of large formations. From 1862 these were often termed Army Corps or Corps, and they are listed with their parent organisation in brackets.
The use of Roman numerals to designate Army Corps is a modern convention used for clarity and convenience. At the time of the Civil War they were referred to typically in words e.g. Eighteenth Corps – or informally by their commander’s name e.g. Slocum’s Corps:
- IV Corps (Cumberland): Gordon Granger
- XI Corps (Cumberland): Oliver Otis Howard….
- Department of the Ohio: John Gray Foster
- District of the Clinch: Orlando Bolivar Willcox
- District of Western Kentucky: Jeremiah Tilford Boyle
- District of Kentucky: Jacob Ammen
- District of Middle Tennessee: Jacob Ammen
- Army of the Ohio: John Gray Foster
- IX Corps (Ohio): Ambrose Everett Burnside
- XXIII Corps (Ohio): Jacob Dolson Cox
There are some anomalies where a particular territorial or field command is not subordinated to a higher level of hierarchy but reports directly to the War Department. These can be identified by reading the indentation of their line.
Status of Command
The command status of any particular organisation is not listed if the officer has been appointed and deemed to have assumed and to hold a command. However, if that status is in some way interim or not substantive the following terms may be used:
Assumed: a commander was appointed or arrived take command;
Arrived: a commander previously appointed arrives to assume command;
Awaited: a commander appointed but not yet arrived to assume command or, if present, not yet formally assumed command;
Interim: a new commander has been appointed but not yet arrived to assume command and the current or incumbent commander remains in post interim pending their arrival;
Retained: a current commander retains command after an organisation or an equivalent renamed organisation is transferred to a new parent command;
Temporary: the commander is appointed temporarily to command in the absence of the incumbent or current commander, or awaiting the appointment of a new commander, or commanding on an interim basis pending confirmation of their own appointment.
Union and Confederate Seniority Lists
This Resource makes it possible to identify on a day-by-day basis, the current grade, rank and order of seniority of the general officers of each side. The accuracy of these records is as sound as possible but the complexity of this topic means that there may be some anomalies especially where two individuals are appointed on the same date.
The Union Seniority list is in grade order as follows, and then by rank order (date) within each grade:
Non-General Officers commanding territorial or field commands
The Confederate Seniority list is in grade order as follows, and then by rank order (date) within each grade:
General ACSA or PACS
Brigadier-General ACSA or PACS
Non-General Officers commanding territorial or field commands
Officers who are still active are in standard font, with their grade and ranking dates.
If they hold a General officer grade in both the US Regular Army and the US Volunteers, both are listed.
If they command one of the listed territorial or field commands, it is also listed after their grade and ranking dates.
Those whose service has ended or is otherwise interrupted are in italic font.
The reason for their interruption or end is listed; this may be one of KIA (killed in action), DOW (died of wounds), Died (of non-combat causes), Resigned, Retired, commission expired, mustered out, Discharged, or one of several other reasons, etc.
For example, a Union Seniority List may include entries such as:
Lieutenant-General USA Ulysses Simpson Grant March 4 1864 to rank from March 2 1864 Major-General USV 16 February 1862 General-in-Chief
Major-General USA Winfield Scott 5 July 1841 to rank from 25 June 1841 Retired 1 November 1861
Brigadier-General USA Edwin Vose Sumner 16 March 1861 Major-General USV 16 July 1862 to rank from 5 May 1862 Died 21 March 1863
Brigadier-General USA Irvin McDowell 14 May 1861 Major-General USV 16 March 1862 to rank from 14 March 1862 Department of the Pacific
Major-General USV John Adams Dix 16 May 1861 Department of the East
Major-General USV Edwin Denison Morgan 28 September 1861 Resigned 1 January 1863
Brigadier-General USV Nathaniel Lyon 17 May 1861 KIA 10 August 1861
Brigadier-General USV Jacob Dolson Cox 17 May 1861 XXIII Corps Ohio temporary

Brigadier-General USV Thomas West Sherman 6 August 1861 to rank from 17 May 1861 Defences of New Orleans
And, for example, a Confederate Seniority List may include entries such as:
General ACSA Albert Sidney Johnston 31 August 1861 to rank from 30 May 1861 KIA 6 April 1862
General ACSA Robert Edward Lee 31 August 1861 to rank from 14 June 1861 Department of Northern Virginia & Army of Northern Virginia
Lieutenant-General PACS James Longstreet 10 October 1862 to rank from 9 October 1862
Lieutenant-General PACS Leonidas Polk 10 October 1862 KIA 14 June 1864
Major-General PACS Earl Van Dorn 19 September 1861 Died 7 May 1863
Major-General PACS George Bibb Crittenden 9 November 1861 Resigned 23 October 1862

Brigadier-General PACS Milledge Luke Bonham 23 April 1861 Resigned 29 January 1862
Brigadier-General PACS Benjamin McCulloch 11 May 1861 KIA 7 March 1862
Clearly, in a voluntary endeavour on this scale, there are sure to be errors and omissions. I have tried to keep these to a minimum, but I trust that when weighed against the broader value of this resource, any such errors will be excused.
I have drawn facts, information and opinions from a variety of sources, from published books and online sources, of varying reliability. I do not claim to have cross-checked all information in a rigorous or scholarly way, and have not referenced sources. However, I have made my best efforts to be accurate and check facts.
I have done my best to achieve practical consistency and clarity. When selecting events and incidents for inclusion or exclusion, I have aimed to record any information that serves to set the evolution in military organisation and command in their context.
I have sought to avoid controversy, whether political or historical, and have generally sought to state moderate, impartial, accepted, or standard interpretations of disputed events or facts, rather than partial, contrary, or controversial ones. I accept responsibility for the interpretations I have made but am open to correction or enlightenment where a sound historical consensus can be shown.
I welcome improvements, additions, corrections, and suggestions within these parameters.
