Despite dismissing him from the White House, Grant did not desert his wartime comrade; in February 1877, he appointed Babcock Inspector of Lighthouses for the Federal Lighthouse Board's Fifth District, a low-profile post that did not attract undue public attention. In 1882, President Chester A. Arthur additionally appointed Babcock as Inspector of Lighthouses for the Sixth District. Babcock was the chief engineer overseeing plans for the construction of the Mosquito Inlet Lighthouse. He died on duty in 1884 when he drowned off Mosquito Inlet in Daytona Beach, Florida. Babcock's historical reputation is mixed; his technical engineering expertise, efficiency, bravery in battle, and Union loyalty were offset by his involvement in corruption, deception, and scandal. Contrary to most of his contemporaries, Babcock also held no racial animosity, which played a part in his advocacy of Grant's plan to annex Santo Domingo.
