After the Battle of Hampton Roads, USS Monitor —“little ship that saved the nation” — seemed perfect. But this illusion was shattered after the James River Flotilla's defeat at Drewry's Bluff. Lt. William Jeffers wrote a detailed report lodging his complaints about the vessel, from intolerable ventilation to questionable design choices, leading to a harsh rebuke from inventor John Ericsson. 

The Battle of Drewry’s Bluff was a dramatic Confederate victory. Richmond was under immediate threat of being captured or at least shelled and destroyed by the Union flotilla, but the cannoneers at Drewry’s Bluff prevented the capital from capture.
