Battle of Trafalgar

The Battle of Trafalgar was a decisive English victory in the Napoleonic Wars. On 21 October 1805, the Royal Navy, led by Lord Admiral Horatio Nelson, defeated a French and Spanish fleet. However, Nelson was killed in the fighting.

The Second Doctor, Ben Jackson and Polly Wright visited Nelson's ship during the battle. The Doctor tried to change history by preventing Nelson's death, but was unsuccessful. (PROSE: H.M.S. TARDIS) On later occasions, the Doctor mentioned his involvement in the battle. (PROSE: Eye of Heaven, PROSE: The Scarlet Empress)

The Eleventh Doctor and Amy Pond visited a different ship during the battle. It was fleeing from what they believed to be a Kraken. It was actually a 21st century aircraft carrier brought back in time by an infestation of Time Roaches. The Doctor sent it back into the Time Vortex, causing the carrier to return to its own time.

The Tenth Doctor mentioned to Rose Tyler that he could take her to witness the battle. (TV: Tooth and Claw)

The First Doctor's companion Vicki Pallister, a native of the 25th century, was unfamiliar with history of the battle and the history of Trafalgar Square. On a visit to London in November 1605, she expressed an interest in visiting the square. When the Doctor told her that the Battle of Trafalgar would not occur for another 200 years, she assumed that he meant that a battle had been fought in Trafalgar Square in 1805. (PROSE: The Plotters)
