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).
Trafalgar Day
The village of Dervock in County Antrim (Northern Ireland) has the only known memorial which takes the form of a stained-glass window depicting Admiral Lord Nelson minutes before he was killed on board HMS "Victory" in 1805. It is believed that this is the only memorial on the island, Nelson's pillar in Dublin (the earliest memorial to Admiral Nelson) having been destroyed in 1966, and in 2015 residents organised their first ever "Trafalgar Day".
