Admiral Dahlgren appointed to replace the ailing Admiral Foote as South Atlantic Squadron commander
Rear Admiral Andrew Hull Foote had been named commander of the South Atlantic blockading squadron to succeed Admiral Alfred DuPont. En route to join his command, however, he fell seriously ill in New York City. As his condition deteriorated, the Navy Department relieved him of his assignment and named Admiral John Dahlgren in his place. Foote died the next evening at his hotel in Manhattan.
