Because of the destruction of any central repository of records in the capital at Richmond in 1865 and the comparatively poor record-keeping of the time, there can be no definitive number that represents the strength of the Confederate States Army. Estimates range from 500,000 to 2,000,000 soldiers who were involved at any time during the war. Reports from the C.S. War Department beginning at the end of 1861 indicated 326,768 men that year, 449,439 in 1862, 464,646 in 1863, 400,787 in 1864, and "last reports" showed 358,692. Estimates of enlistments throughout the war range from 1,227,890 to 1,406,180. served as
commander-in-chief and provided the overall strategic direction for Confederate land and naval forces in both eastern and western theaters. The following men had varying degrees of control: •
Robert E. Lee was "charged with the conduct of military operations in the armies of the Confederacy" from March 13 to May 31, 1862. He was referred to as President Davis' military adviser but exercised broad control over the strategic and logistical aspects of the Army, a role similar in nature to the current
Chief of Staff of the United States Army (not developed until beginning in the early 20th century). On June 1, he assumed command of the
Army of Northern Virginia, which was considered the most important of all the Confederate field armies. •
Braxton Bragg was similarly "charged with the conduct of military operations in the armies of the Confederacy" from February 24, 1864 (after he was relieved of field command following the
Battle of Chattanooga) to January 31, 1865. This role was a military advisory position under Davis. • Lee was formally designated
General in Chief of the Armies of the Confederate States by an act of Congress (January 23, 1865) and served in this capacity from January 31 to April 9, 1865. The lack of centralized control was a strategic weakness for the Confederacy, and there are only a few examples of its armies acting in concert across multiple theaters to achieve a common objective. One instance occurred in late 1862 with Lee's invasion of
Maryland, coincident with two other actions: Bragg's invasion of
Kentucky and
Earl Van Dorn's advance against
Corinth, Mississippi. All three initiatives were unsuccessful, however. Georgia Governor
Joseph E. Brown was an extreme case of a Southern States Rights advocate asserting control over Confederate soldiers: he defied the Confederate government's wartime policies and resisted the military draft. Believing that local troops should be used only for the defense of Georgia, Brown tried to stop Colonel Francis Bartow from taking Georgia troops out of the state to the First Battle of Bull Run. Many of the Confederacy's senior military leaders (including Robert E. Lee,
Albert Sidney Johnston, and
James Longstreet) and even President Jefferson Davis, were former U.S. Army and, in smaller numbers, U.S. Navy officers who had been opposed to, disapproved of, or were at least unenthusiastic about secession, but resigned their U.S. commissions upon hearing that their states had left the Union. They felt that they had no choice but to help defend their homes. President Abraham Lincoln was exasperated to hear of such men who professed to love their country but were willing to fight against it.
Personnel organization As in the
U.S. Army, the Confederate Army's soldiers were organized by military specialty. The combat arms included infantry, cavalry, and artillery. Although fewer soldiers might comprise a squad or platoon, the smallest
infantry maneuver unit in the Army was a company of 100 soldiers. Ten companies were organized into an infantry regiment, which theoretically had 1,000 men. In reality, as disease, desertions and casualties took their toll, and the common practice of sending replacements to form new regiments took hold, most regiments were greatly reduced in strength. By the mid-war, most regiments averaged 300–400 men, with Confederate units slightly smaller on average than their U.S. counterparts. For example, at the pivotal
Battle of Chancellorsville, the average U.S. Army infantry regiment's strength was 433 men, versus 409 for Confederate infantry regiments. Rough unit sizes for CSA combat units during the war: • Corps - 24,000 to 28,000 • Division - 6,000 to 14,000 • Brigade - 800 to 1,700 • Regiment - 350 to 400 • Company – 35 to 40 Regiments, which were the basic units of army organization through which soldiers were supplied and deployed, were raised by individual states. They were generally referred by number and state, for example
1st Texas,
12th Virginia. To the extent the word "
battalion" was used to describe a military unit, it referred to a multi-company task force of a regiment or a near-regimental size unit. Throughout the war, the Confederacy raised the equivalent of 1,010 regiments in all branches, including militias, versus 2,050 regiments for the U.S. Army. Four regiments usually formed a
brigade, although as the number of soldiers in many regiments became greatly reduced, especially later in the war, more than four were often assigned to a brigade. Occasionally, regiments would be transferred between brigades. Two to four brigades usually formed a
division. Two to four divisions usually formed a
corps. Two to four corps usually formed an army. Occasionally, a single corps might operate independently as if it were a small army. The Confederate States Army consisted of several field armies, named after their primary area of operation. The largest Confederate field army was the
Army of Northern Virginia, whose surrender at
Appomattox Courthouse in 1865 marked the end of major combat operations in the U.S. Civil War.
Companies were commanded by captains and had two or more lieutenants. Regiments were commanded by colonels. Lieutenant colonels were second in command. At least one major was next in command. Brigades were commanded by brigadier generals although casualties or other attrition sometimes meant that brigades would be commanded by senior colonels or even a lower grade officer. Barring the same type of circumstances that might leave a lower grade officer in temporary command, divisions were commanded by major generals and corps were commanded by lieutenant generals. A few corps commanders were never confirmed as lieutenant generals and exercised corps command for varying periods as major generals. Armies of more than one corps were commanded by (full) generals.

general,
lieutenant general,
major general, and
brigadier general), but all wore the same insignia regardless of grade. This was a decision made early in the conflict. The Confederate Congress initially made the rank of brigadier general the highest rank. As the war progressed, the other general-officer ranks were quickly added, but no insignia for them was created. (Robert E. Lee was a notable exception to this. He chose to wear the rank insignia of a colonel.) Only seven men achieved the rank of (full) general; Unlike the Union, which had fairly stable military departments through most of the Civil War, Confederate departments were constantly being formed, reformed, and renamed as the war progressed. The original two departments, formed at the beginning of the Civil War, were "Department No 1" (later incorporated into the Department of Louisiana) and "Department No 2" (later becoming the
Western Department). In Virginia, where hostilities broke out almost immediately after the start of the war, the "Alexandria line" was established as the first Confederate administrative body in this area. This was later expanded to formal military departments in the following order: • Department of Alexandria • Department of the Potomac • Department of Northern Virginia Virginia also maintained the following smaller departments which fluctuated as the war progressed: • Department of Norfolk • Department of Fredericksburg • Department of Richmond (operated in tandem with the Department of Henrico) • Department of Southwestern Virginia • Department of the Peninsula In the Shenandoah Valley, the first Confederate administrative command was set up at Harper's Ferry, later becoming the
Valley District, directly subordinate to the Army of the Shenandoah. The Shenandoah Valley was without a department for most of the war, militarily controlled by Army of the Northwest and the Army of the Valley, before finally being declared the
Trans-Allegheny Department. Elsewhere in the Confederacy, the following major departments were formed which operated throughout most of the war: • Department of Louisiana • Department of Tennessee •
Department of North Carolina • Department of South Carolina • Department of Georgia The Union attack on
Vicksburg, Mississippi also brought about a succession of departments known as: • Department of Mississippi and East Louisiana • Department of Alabama and East Mississippi • Department of Alabama, Mississippi, and Eastern Louisiana The entire Mississippi region was eventually merged into the
Trans-Mississippi Department, one of the largest departments of the war. At the same time, departments were being formed further west as the: •
Western Department •
Department of Texas • Department of the Indian Territory Battles in Tennessee, and shifting fronts in that region, also brought about the need for new departments in that region, most of which reported directly to the Army of Tennessee under
John Bell Hood. Hood would directly command the following three departments at the same time as his service as an Army commander: • Department of East Tennessee •
Department of East Tennessee and West Virginia • Department of Tennessee and Georgia In 1864, Robert E. Lee held the idea for "super theaters" encompassing vast areas of the south, as follows: • Department of North Carolina and Southern Virginia - an expansion of the Department of Southern Virginia • Department of South Carolina, Georgia, and East Florida • Department of South Carolina and Georgia - later expanded to the Department of South Carolina, Georgia, and Florida Lesser departments, without much combat activity, were: • Department of West Florida • Department of Alabama and West Florida (expansion of the District of Alabama) • Department of Middle and Eastern Florida • Department of Western Kentucky ==Supply and logistics==
