Detailed Strength and Casualty Numbers
for the Army of the Potomac in the Battle of Gettysburg

These numbers are rounded approximations rather than a precise count. Most of the information comes from the Official Records, but it is often in disagreement between regimental and brigade records or with information from unitmonuments or postwar writing by veterans.

“Strength” is the number of men “present for duty equipped,” those actually ready for combat on the battlefield. This does not count units that were not on the Gettysburg battlefield on July 1-3, such as Huey’s Cavalry Brigade and the two Vermont regiments guarding trains in the army’s rear. They also do not count men who were on sick call or in the hospital, or were detailed to supply or other duties which took them out of the battle lines.

“Killed” counts men who were killed or who died soon after a mortal wound. “Wounded” counts anyone who was injured, from lightly hit men who did not leave the ranks to men who died of their wounds days or months after the battle. “Missing” also covered a wide category, basically anyone who did not answer roll call but whose fate was not known. These might be men who were captured, or ran away, whose body could not be identified, or who crawled into the woods to die and whose body was never found. If the fate of these men became known at a later date the numbers of killed and wounded might be adjusted in regimental histories and veteran’s memoirs, but were almost never corrected in the official reports – one cause of the lack of precision in tracking Civil War battlefield casualties.
