The Battle of Trafalgar was a naval engagement between the British Royal Navy and the combined fleets of the French and Spanish Navies during the War of the Third Coalition of the Napoleonic Wars (1803–1815).
A ship of the line was a type of naval warship constructed during the Age of Sail from the 17th century to the mid-19th century. The ship of the line was designed for the naval tactic known as the line of battle, which depended on the two columns of opposing warships maneuvering to volley fire with the cannons along their broadsides. In conflicts where opposing ships were both able to fire from their broadsides, the opponent with more cannons firing – and therefore more firepower – typically had an advantage. Since these engagements were almost invariably won by the heaviest ships carrying more of the most powerful guns, the natural progression was to build sailing vessels that were the largest and most powerful of their time.
HMS Bellerophon, known to sailors as the "Billy Ruffian", was a ship of the line of the Royal Navy. A third-rate of 74 guns, she was launched in 1786. Bellerophon served during the French Revolutionary and Napoleonic Wars, mostly on blockades or convoy escort duties. She fought in three fleet actions: the Glorious First of June (1794), the Battle of the Nile (1798) and the Battle of Trafalgar (1805). While the ship was on blockade duty in 1815, Napoleon boarded Bellerophon so he could surrender to the ship's captain, ending 22 years of almost continuous war between Britain and France.

HMS Superb was a 74-gun third-rate ship of the line of the Royal Navy, and the fourth vessel to bear the name. She was launched on 19 March 1798 from Northfleet, and was eventually broken up in 1826.

Keats famously spent only one night out of the ship during four and a half years out of a home port. She also served as his flagship from early 1808 until she was paid off in 1809.

Berwick sank shortly thereafter in a storm.
HMS Swiftsure was a 74-gun third rate ship of the line of the British Royal Navy. She spent most of her career serving with the British, except for a brief period when she was captured by the French during the Napoleonic Wars in the action of 24 June 1801.

Vice Admiral Sir Richard Grindall KCB was an officer in the British Royal Navy whose distinguished career during the American War of Independence, the French Revolutionary War and the Napoleonic Wars was highlighted by his presence at the battle of Trafalgar in 1805, Despite being slow and ungainly, his 98-gun ship Prince was instrumental in the final stages of the battle and especially in the chaotic storm which followed, when many of the British fleet would have been lost but for the efforts of Grindall and other captains of largely undamaged ships.
HMS Edgar was a 74-gun third-rate ship of the line of the Royal Navy, that saw service in the American Revolutionary, French Revolutionary and Napoleonic Wars. Launched in 1779, she fought in the battles of Cape St Vincent and Copenhagen, two of the major naval engagements of the wars.
