Letters from Second Cavalry and Brevet Brigadier-General

This is a list of American Civil brevet generals that served the Union Army. This list of brevet major generals or brevet brigadier generals currently contains a section which gives the names of officers who held lower actual or substantive grades in the Union Army, were not promoted to full actual or substantive grade generals during or immediately after the war, but were awarded the grade of brevet major general or brevet brigadier general, almost always in recognition of service, not as any form of promotion. The first section shows these officers' actual grades and regiments or assignments. Dates in the list are explained below.
