Battle of Trafalgar
The Battle of Trafalgar (21 October 1805) was a naval engagement fought by the British Royal Navy against the combined fleets of the French and Spanish Navies, during the War of the Third Coalition (August–December 1805) of the Napoleonic Wars (1796–1815).

The Treaty of Amiens in 1802 provided for a temporary truce in hostilities, only to be broken in 1804 when the British captured a Spanish treasure fleet off Cadiz. The French planned an invasion of England in the coming year; the Spanish fleet was to be an integral part in assisting this invasion. At the Battle of Trafalgar in 1805, the Spanish navy and the French Mediterranean fleet, attempting to join forces with the French fleets in the north for the invasion, were attacked by Admiral Lord Nelson at the head of a British fleet in one of history's greatest naval engagements. The disastrous defeat that the Spanish and French suffered assured British dominance at sea and seriously shook the resolve of the Spanish who began to doubt the usefulness of their always mutually suspicious alliance with Napoleon's regime.
