The 91st Pennsylvania Volunteer Infantry

Dedicated to the memory of Carol Ide (1958-2012)

Origins The 91st was formed from volunteers in Philadelphia, and most of its men were born in Pennsylvania.

Endings Almost 10% of the regiment died in service. 654 men mustered out with the regiment at the end; 128 of them were original members.

Washington The 91st guarded several famous Confederate female spies, and also shot a prisoner who was a boyhood friend of John Wilkes Booth.

Life Most of the regiment's time was taken up, not with battles, but with training and other duties.


After the war Colonel (Brevet Major General) Gregory was the only Assistant Commissioner of the post-war Freedman's Bureau who could be called an abolitionist.

Fact of the week [updated Sundays]

#499 James Banni (B) is an example of a difficulty in deciding who served in the regiment. According to his compiled service record, he enlisted on 3 May 1862, and deserted on 8 May 1862. The record also claims: 'This name should not have appeared on this Roll' (sc. the May-June 1862 muster roll). Why? Perhaps because there was '[n]o evidence of muster in'. I've added him to my statistics, because he is on one of the muster rolls--but whether he should be included isn't at all obvious.

Battles and casualties Because of poor generalship, the 91st had no spectacular successes on the battlefield. But they paid a heavy price: 114 of them were killed or mortally wounded in battle.

After the war Many men received pensions, and joined veterans' associations. The last death I known of occurred in 1940.
