Patrick Troy was an Irish immigrant and day laborer living in Cornwall Bridge with his mother and six younger siblings when the war began. He enlisted with Company G of the 19th C.V.I. (later the 2nd Heavy Artillery) on August 7, 1862, and was promoted to Corporal on March 3, 1864. Troy was wounded at the Battle of Winchester on September 19, 1864. As a result of his injury, his arm was amputated. After an initial recovery, Troy relapsed and died in transit to the hospital at Baltimore on October 20, 1864.

Troy was survived by his mother, Mary Troy of Warren, who was a destitute widow. Mary was illiterate and signed her name with an X on the pension documents. Mary’s application was supported by Edward F. Gold, Patrick Duggan, David Hollister, Miles Hoyt, Charlotte Hoyt, Frederick Butler, and Eliza Butler, all of Cornwall.
