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]

#549 John A Mootheart (B) deserted on 1 March 1864. (He had deserted once before, but returned when Lincoln proclaimed an amnesty for deserters who voluntarily returned.) Is he the John Moothart who was convicted of counterfeiting in August 1866? That John Moothart had a brother Charles, who was also tried but acquitted. And a Charles Moothart was a notorious horse thief, along with his brother William. Note that John claimed to be a chairmaker when he enlisted in the 91st, and in the 1863 Philadelphia directory, Charles, George, and William were chairmakers, and John was a chaircaner, with all of them living at 872 Darien Street.

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.
