The Burning of the USS Philadelphia Historical Battle - Determined to put an end to predatory raids on merchant vessels, the United States has declared war on the Barbary pirates in North Africa. An auspicious start to the conflict quickly turned into disaster and disgrace when the frigate USS Philadelphia was captured intact by Barbary pirates. However, one brave young American lieutenant was unwilling to let the vessel remain in enemy hands. Assembling a group of volunteers, Stephen Decatur set sail to destroy the frigate and salvage the US Navy's reputation.
