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.
What's new

Fact of the week [updated Sundays]

#516 Of the 19 letters from Andrew Brown (C) in his father's pension certificate file, four complain about not getting letters. On 29 March 1862, he complains that he has written a letter every week (presumably since arriving in DC), and received only two letters from his father and sister. On 26 August 1862, he complains that he wrote the day before they left Alexandria, and hadn't received an answer. On 3 April [1863], he asks how Thomas is, saying, 'I suppose he expects me to write to him[--]if so[,] he should have answered the last letter I sent to him'. And on 7 June 1864, he writes that he has written five or six letters and received only one, adding: '[T]his is the last I intend to write till I get an answer with writing paper, envelopes, + stamps'. Fortunately, the last letter from him, dated 17 June 1864, just two days before he died, doesn't include any complaints.

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.
