Answer:
The Union Navy's attack on the city of New Orleans and the capture of the Mississippi River during the American Civil War were led by Admiral David Farragut. In April 1862, Farragut commanded a fleet of ships, including ironclads and mortar boats, and successfully bypassed the Confederate defenses at Forts Jackson and St. Philip. His fleet then sailed up the river, engaging and defeating the Confederate naval force near New Orleans. Farragut's victory was a significant strategic achievement for the Union, as it opened up the Mississippi River, effectively cutting the Confederacy in half and facilitating further Union military operations.
