After a thirty-six hour bombardment, Major Anderson accepted a ceasefire in the early afternoon and, after an agreement was made largely on Anderson's earlier terms, made preparations to evacuate Fort Sumter the following day. His garrison had suffered no fatalities during the shelling, though an estimated 3000 rounds had been fired at the fort and it was essentially in ruins. The evacuation proceeded as planned, the next day. (By John Osborne)
