Bio: Frederic W. Dorr was a U.S. Coast Survey Topographical Engineer sent by Superintindent Bache to assist Union field officers. Donn served with the Armies of the Potomac, Cumberland, and James, and also did work around the Virginia Peninsula where he contracted malaria while on a special reconnaissance mission at Harrison's Landing. He was assigned to General Sherman's command in 1864, marching from Savannah to Raleigh, where he saw General Joe Johnston's surrender on April 15, 1865, nearly a week after Appomattox. Dorr eventually succumbed to the malaria after the war.
