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).
HMS Thunderer (1783)
Later that year she fought at the Battle of Trafalgar under the command of her First Lieutenant, John Stockham. The surgeon on board was Scotsman James Marr Brydone, who was the first of the main British battle fleet to sight the Franco-Spanish fleet. "Thunderer" signalled the "Victory" and three minutes later battle orders were signalled to the British fleet beginning the Battle of Trafalgar.
