HMS Neptune (1797)

HMS Neptune (1797 at Deptford) was a 98-gun 2nd rate ship of the line which fought at the Battle of Trafalgar. After the battle, it was the Neptune that towed the crippled Victory, bearing Nelson's body, back to Gibraltar.

Combatants at Trafalgar also included the French ship Neptune and the Spanish ship Neptuno.

Neptune served as the flag ship for Rear Admiral Sir Alexander Cochrane leading the fleet that captured the French colony of Martinique in the West Indies in 1809.

This was the second of nine ships to bear the name Neptune. She was laid up in ordinary in 1810 and broken up 1818.
