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]

#536 Isaachar Morgan (G) applied for a pension on 21 February 1909, without success. Under the Act of 27 June 1890, anyone who (a) served ninety days or more, (b) was honorably discharged, and (c) couldn't make a living from manual labor, was eligible for a pension. Since Morgan was 81 years old, he probably met condition (c), and the regimental records I've seen do not suggest his discharge was in any way dishonorable. That suggests he failed condition (a). He enlisted and was mustered in on 2 March 1865, and was discharged on 30 May 1865. If the first and last days are included, that's 90 days. Perhaps dates were calculated as intervals, so that he served only 89 days.

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.
