500 Dollars - Elizabeth II HMS Shannon and USS Chesapeake

The engagement between HMS Shannon and USS Chesapeake on June 1, 1813, lasted exactly eleven minutes — one of the most lopsided frigate actions of the War of 1812. The Chesapeake's crew was largely green and had never worked together as a unit; Shannon's captain, Philip Broke, had spent years drilling his men in gunnery at a time when the Royal Navy considered such training largely unnecessary. The result was a British broadside so disciplined it effectively ended the battle before boarding parties were needed.

Broke was severely wounded in the melee, never fully recovered, yet was knighted for the action.
