List of American Civil War generals

A general officer of the Union Army, whether of the United States Regular Army or United States Volunteers, and whether of full or brevet grade (or rank), could legally be promoted to a grade of general officer only by appointment by the President of the United States and confirmation by the United States Senate. Field promotions, exercise of command duties or brevet grade promotions alone were insufficient to qualify an officer as an actual, substantive grade general.[9]

Similar to the procedures of the US, in the Confederate States of America ("CSA") an officer could legally be made a Confederate general only by appointment by the President of the Confederate States and confirmation by the Confederate States Senate. Officers holding rank on the date of enactment of the first Confederate law on the subject of appointment of general officers, May 21, 1861, were permitted to keep those ranks.[10] And at the end of the war, several appointments to the rank were not brought before the Confederate States Senate for confirmation. A complicating factor for the Confederate Armies, was their reliance on, and organization around, standing State Militias. A senior officer might hold the rank of general in his state militia, as a separate matter from any prior rank. In most states, the rank of general at the level of a state militia was conferred by the State's Governor. Some of those state appointments predated the start of the Civil War and some occurred after. Not all the State Militia appointments to the rank of general were translated into the same rank at the level of the Confederacy. As a result, while the Union and Confederate rules for the rank of general were similar, the CSA experienced a greater diversity at this rank in practice. As noted, while General Wright, Ezra J. Warner and other historians profess to use these criteria to identify Civil War generals, in fact they have inconsistently included about 25 names of officers for each army who do not actually meet the criteria and it is now difficult not to take note of at least these extra officers in lists of Civil War generals.

Although the Eichers take a stricter view of which Civil War officers should be considered full grade generals, Ezra J. Warner and other historians have accepted the individuals shown in the (General Wright) War Department memos as the officers who should be included in lists of actual Civil War generals.[11] Thus, although 22 Union officers and 5 Confederate officers had their appointments canceled and 1 Union officer and 3 Confederate officers declined appointment to the grade of brigadier general, General Wright included them and Mr. Warner decided to accept them as full grade generals. Warner based his conclusion on the actual appointment of almost all of them, the confirmation of some of them, political considerations which may have led to the cancellations or failure of confirmations and because they seem to have exercised command. These commands were exercised mostly for longer periods of time than the periods of time which those officers who exercised such commands on a temporary or emergency basis usually acted and who usually were not appointed or nominated as general officers by the respective presidents at all.[12] This conclusion is still inconsistent with the criteria that these authors state they are using, but at least they have given a plausible rationale for adopting Wright's full list. In doing so, they have often identified officers who were not full generals but who are notable and may deserve recognition for their actions in high commands. A few other officers in both armies who received only temporary general officer appointments or who had been killed in action or mortally wounded before they could be advised that their appointments as generals had been confirmed are also on these lists. They are perhaps the most understandable of the exceptions.[13]

The Union Army was supported in the field by very few state militia generals who had not been taken into the United States Volunteers, the main body of the Union Army, along with their state regiments or were not promptly added to the federal service when it appeared they would exercise active field command.[14] Historians have recognized a number of Confederate officers who exercised high command but were never formally appointed as generals. The Union Army also had at least a few officers assigned to command or temporarily placed in command of units whose generals had been killed, wounded or become unavailable, but who did not receive full rank appointments, just as the Confederate Army had.

In addition, Warner, depending on Wright, writes that 1,367 Union officers who were not promoted to full grade substantive general were awarded brevet general officer rank.[15] Many other compilations of such brevet generals are within 10 of this number.[16] Most of the 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.[17] By the time of the Civil War, these brevet appointments were honorary titles, much like medals or commendations, 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. Even if significant numbers of brevet grade appointments had been awarded earlier in the war, except in a few special instances (sitting on court martial panels, special assignments, command of different units operating together with commanding officers of equal rank), they had not extra responsibilities, privileges or pay and would have meant little more than the award of a medal. Although most of the brevet awards were for faithful or meritorious or distinguished service, some were for more extraordinary acts of gallantry.[18]

Although the number of Confederate generals may not be swollen by the possible addition of well over 1,300 brevet generals whose actual rank was below brigadier general as the Union general list could be, as many as 159 "might have beens" and 226 militia officers have been identified or considered by some authors as Confederate generals of some sort.[19] Ten officers who were assigned to duty by General Edmund Kirby Smith in the Trans-Mississippi Department after communications were cut off or severely slowed down by Union forces securing control of the Mississippi River are among the "might have beens." Warner and the Eichers both warn that some false or mistaken claimants emerged over the years and that unintentional though nonetheless mistaken Civil War general officer identifications have been made and published over the years.[20]

Until Ulysses S. Grant was appointed lieutenant general and General-in-Chief in 1864, the Union Army had only two grades of general: major general and brigadier general.[21] In the Union Army, major generals commanded armies as well as corps and divisions, the armies’ largest units. Seniority was determined by the date of rank stated in the Senate's confirmation resolution, which could have been a date earlier than the confirmation date. Otherwise, rank would be determined by the order of names on the lists of multiple officers confirmed in the same resolution on the same date to rank from the same date.[22]

The Confederate Army had four grades (or levels or "ranks") of general officers, much like the modern U.S. Army: general, lieutenant general, major general and brigadier general.[23] In theory, full generals commanded armies, lieutenant generals commanded corps, major generals commanded divisions and brigadier generals commanded brigades. Lower ranking officers might temporarily command a unit designated for a higher ranked commanding officer when the unit's commander was killed, wounded or unavailable. Some small Confederate armies of about corps size were formed and were commanded by lieutenant generals.

The Confederate Regular Army did not proceed beyond the planning stage and the appointment of six brigadier generals and a few lower grade officers. Since the Provisional Army, Confederate States (PACS) was the only Confederate Army that was organized by the Confederacy, the Confederate Army and the PACS were identical. Additional reference and distinction between a regular Confederate Army and the PACS is superfluous except perhaps as a minor historical footnote.[24]

Due to the pre-Civil War U.S. Army system of promoting officers based strictly upon seniority, the general officers, chief staff officers and full colonels of the small pre-Civil War army were not only few in number but were almost all of advanced age (over half were in their seventies). Among the top field officers, 11 of the 19 colonels of the line had fought in the War of 1812 as commissioned officers.[25] The following tables show the general officers and top staff officers of the U.S. Army in early 1861 and their ages, lengths of service in grade, whether they adhered to the Union or Confederacy and in many cases who their successors were.

In addition, an act of Congress of March 2, 1849 authorized the President to appoint a suitable person as Judge Advocate of the army, to be taken from the captains of the army. Captain John F. Lee of the Ordnance Department was accordingly appointed, and held the office until it was superseded by the legislation of 1862.[50]

With few active officers to fill many commands, the two Civil War armies had to look to other persons for military leadership. Lower ranking U.S. Army officers, Mexican–American War veterans and military school graduates in civilian life would fill many top and field grade officer positions. Many positions were also filled by foreign emigres, some of whom had military training, and politicians and other civilians with no military training. Some became good generals but many others were poor commanders.

At the outbreak of the Civil War, 296 U.S. Army officers of various grades resigned. Of these, 239 joined the Confederate Army in 1861 and 31 joined after 1861. Of these Confederate officers from the U.S. Army, 184 were United States Military Academy graduates. The other active U.S. Army 809 officers, 640 of whom were West Point graduates, remained with the Union. Of the approximately 900 West Point graduates in civilian life at the beginning of the war, 114 returned to the Union Army and 99 joined the Confederate Army.[51] Norwich University in Northfield, Vermont furnished more officers to the war than any other military school except the United States Military Academy and Virginia Military Institute. The school contributed 523 officers to the Union Army and 34 to the Confederate Army.[52] Norwich was the only military college in the Northern states, other than West Point, which had a sizable number of military trained alumni who could provide a significant number of officers to the Union Army.

Of the 1,902 men who had ever attended Virginia Military Institute in Lexington, Virginia, 1,781 fought for the Confederacy. One-third of the field officers of Virginia regiments in 1861 were V.M.I. graduates.[53] The Citadel, The Military College of South Carolina provided at least 6 general officers to the Confederate Army as well as 49 field grade officers, and 120 company grade officers.[54] Another alumnus of The Citadel, Colonel Charles C. Tew, was killed on the eve of his promotion to brigadier general.[55]

The lists of Union and Confederate general show the 583 Union Army generals and the 425 Confederate Army generals included in the Wright War Department memos and Mr. Warner's books at their highest grades achieved during the course of the war.[56] Using these sources results in the inclusion of about 25 "might have beens" in both armies. These should be among the most prominent officers in this category and not near the number of "might have beens" identified by the Eichers. Notes should identify most, if not all, of those who are in this category. The lists thus include the 554 to 564 Union generals and 398 to 401 Confederate generals identified as actual, substantive generals by most historians, including the Eichers, and at least some of the others who might appear on other lists or in Civil War writings as generals. A few notable militia generals and some of the notable brevet general officers have been added, at least in the current absence of a separate list of Union brevet general officers. A few additional Confederate militia or acting generals or 'might have beens" are also currently added to the Confederate general list in a separate section at the end of that list. Most of the generals' names in both lists are linked to Wikipedia articles on them. Articles on the others (shown in red links because there are no existing articles about those officers) are planned.
