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]

#540 If I've reconstructed Adam Guthrie's story correctly, he seems to have been unduly eager to join the army. He enlisted in the 91st on 24 November 1862, and was discharged on 16 March 1863, without being taken up on any of the 91st's muster rolls, because of organic heart disease contracted since enlistment. (I admit I'm a bit dubious. Did the examining board want to protect the examining surgeon from accusations of having missed the organic heart disease?) He had been unfit for duty for sixty days in the previous two months, and was rated two-thirds disabled. Nevertheless, just four months later, on 15 July 1863, he enlisted in the 26th Pennsylvania (from which he was transferred to the 99th Pennsylvania). (How did he pass the physical? And did he admit that he had been discharged on disability? Perhaps not, and that may be why he didn't mention his service in the 91st when he applied for a pension.) He served as 'a good and efficient soldier' until 8 March 1865, when he was 'taken with a fit', after developing a severe cold from exposure while on picket, which led to paralysis on his right side. He died of apoplexy, about a year later, on 21 May 1866.

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.
