The fate of the French fleet at the Siege of Toulon marked one of the earliest significant operations by the British Royal Navy during the French Revolutionary Wars. In August 1793, five months after the National Convention declared war on Great Britain, thus drawing Britain into the ongoing War of the First Coalition, the government of the French Mediterranean city of Toulon rose up against the Republican national government in favour of the Royalist faction. Toulon was the principal French naval port on the Mediterranean and almost the entirety of the French Mediterranean Fleet was anchored in the harbour. After negotiations the British commander in the Mediterranean, Admiral Lord Hood, the city's Royalists seized control and British forces, alongside allies from Spain, Naples and Sardinia entered the city, seizing the fleet and preparing defences against the inevitable Republican counterattack.
