To execute the planned complete naval blockade of the Confederacy, the Southern Blockading Squadron sailed from Hampton Roads off Norfolk, Virginia under Samuel Francis DuPont. With almost fifty ships and around fifteen thousand troops under General W.T. Sherman, this was easily the largest U.S. naval force gathered under one command up to that time. The force's first objective was the securing of a land base for its blockading operations and Port Royal, South Carolina was captured just over a week later. (By John Osborne)
