"Sophronia" anchored some 3,000 yards from Fort Jackson and began lobbing mortar shells into the fort, at 1000, at the rate of six an hour. The bombardment continued intermittently until Admiral David Farragut had safely dashed past Forts Jackson and St. Philip on the morning of the 24th. New Orleans, Louisiana, fell to Admiral Farragut the next day, and the two forts surrendered on 28 April as they were cut off from their source of supplies and Union forces were prepared to attack them from three sides.
