Samuel Tilden Kingston, it was said, was not the same man after Confederates captured and imprisoned him in Richmond’s Libby Prison. The assistant surgeon of the Second New York Cavalry, he fell into enemy hands on March 1, 1864, during Union Col. Ulric Dahlgren’s failed raid on Richmond. Kingston was locked up in a basement dungeon of Libby and treated harshly by his captors. Conditions turned from bad to worse when papers ordering the assassination of Confederate President Jefferson Davis were reportedly discovered on the body of Dahlgren after he was killed.
Kingston was released after a short time in confinement, and he later returned to his regiment. He survived the war and became a physician and druggist in Oswego, N.Y. According to a document in his pension file, Kingston was “a very odd & peculiar person.” His wife also noted that he was peculiar with respect to arranging his financial affairs. Kingston died in 1889 at age 53.
