Fester beat me to it: so I'll go for the extra point:
Admiral Jervis with Commodore Nelson defeated the Spanish fleet in 1797 at a second Battle of Cape St. Vincent on 14 February 1797.
A bit more detail on the actual painting:

The naval Battle of Cape St. Vincent took place on February 14, 1797, near Cape St. Vincent, Portugal, between a British fleet and a Spanish fleet and was an important battle during the Wars of the French Revolution.
