The new
French Republic had declared war on the
Kingdom of Great Britain on 1 February 1793, following years of rising tension. The British immediately laid preparations for the deployment of a large fleet to the
Mediterranean Sea, in order to enact a
blockade on the French Mediterranean Fleet based at
Toulon. The British Mediterranean fleet was dispatched in a series of divisions during the spring, led by
Vice-Admiral Lord Hood, and numbered 21
ships of the line and associated
frigates. Among this force was the 64-gun small
ship of the line HMS Agamemnon, under the command of Captain
Horatio Nelson. Hood's fleet entered the Mediterranean at the end of June 1793, and on arriving off Toulon found the French naval base in open revolt against the
Jacobin National Convention. Hood negotiated the surrender of the port and the French fleet, landing substantial troops and stores to defend it from French Republican counterattack. Hood was aware of the vulnerability of his position and sought a nearby safe harbour, settling on the island of
Corsica. Corsica had been invaded and annexed by the French in 1768 and its inhabitants were still rebellious; shortly before Hood's arrival an attempt by the French to arrest the island's leader
Pasquale Paoli had led to an uprising which had driven the French garrison into a three fortified towns on the northern coast. Hood sent a squadron under
Commodore Robert Linzee to attempt to negotiate the surrender of these strategically important positions, with orders that if these overtures failed, Linzee was to attack the port of
San Fiorenzo. The attack failed, and Linzee withdrew to
Cagliari on the allied island of
Sardinia. In early October,
Agamemnon was sent to join Linzee for an operation against a French convoy anchored in the neutral port of
Tunis; ==Battle==
