Almost every genealogist has ancestors who served in the military. At times it can be confusing to understand how the Army is organized and how large each unit would be. Read on.
Unit size and type may vary slightly from early conflicts. This table will make it easy to understand more about Army organization and your ancestor’s role. The chart below is typical of a more modern-era Army.
|UNIT||NUMBER OF MEN||COMMANDED BY|
3 or more Batallions
The next chart shows the organization of the Army during the Civil War.
Both Union and Confederate sides had more than one Army. For example, Robert E. Lee led the Army of Northern Virginia; however the Confederates also had the Army of Tennessee. On the Union side, there was the Army of the Potomac, the Army of the Cumberland and the Army of Ohio.
While the branches were combined very early in the war, over the next year or so the artillery and cavalry were split into their own branches. By 1863, it would have been unusual for different branches to be combined within a brigade (infantry, cavalry, and artillery).
