Battle of Drewry's Bluff

The Battle of Drewry's Bluff, also known as the Battle of Fort Darling, or Fort Drewry, took place on May 15, 1862, in Chesterfield County, Virginia, as part of the Peninsula Campaign of the American Civil War. Five Union Navy warships, including the ironclads USS Monitor and Galena, steamed up the James River to test the defenses of Richmond, Virginia, the Confederate capital. They encountered submerged obstacles and deadly accurate fire from the batteries of Fort Darling at Drewry's Bluff, which inflicted severe damage on Galena. The Union Navy was forced to turn back.
