Lt. Rockefeller was awarded a Medal of Honor for his actions at Fort Blakely, Alabama, in 1865. He stayed in the Regular Army after the war. He was sent to the Philippines during the Spanish-American War, and shortly after arriving there in April, 1899, he "went to inspect outposts, and was never again seen by his comrades. For some time it was supposed that he had been assassinated and his body thrown into one of the wells or pits in the vicinity of his camp. Every effort was made to discover his whereabouts or to recover his body in case he had been killed, but to no avail." (From New York Times, May 27, 1900)
