Union Brigades (and larger units)Union Brigade (and larger unit) Histories


The brigade was the common tactical unit for both cavalry and infantry in the Civil War. It consisted, usually, of 4-6 regiments and would have a strength of, say, 4,000-5,000 men, all of whom were commanded by a brigadier general.

The division was the next largest unit in the Civil War armies and consisted normally of three brigades of 12,000-15,000 men, all of whom were commanded by a major general (although brigadier generals occasionally were in command).

The corps was generally composed of two or more divisions, and except for a corps of cavalry, consisted of all branches of service. There were 43 corps, designated by Roman numerals, established in the Union army prior to the end of the Civil War, all commanded by a major general.
