 In anticipation of the start of Britain 's involvement in the French Revolutionary War after the execution of King Louis XVI , Agamemnon was recommissioned on 31 January 1793 . She was placed under the command of Captain Horatio Nelson , and after provisioning joined the fleet lying at anchor at the Nore . She subsequently sailed to join the Mediterranean fleet under Vice @-@ Admiral Hood , which was blockading the French port of Toulon . On 27 August the town of Toulon declared its allegiance to the Royalist Bourbon cause , and Hood 's fleet moved in to take control of the naval dockyard and the 30 French ships of the line that were in the harbour . After capturing 19 of the ships , Agamemnon was sent to Naples to ask King Ferdinand IV for reinforcements with which to secure the town ; he agreed to provide 4 @,@ 000 men . When the revolutionary army , commanded by Napoleon Buonaparte , launched its assault against Toulon , the troops proved insufficient to hold it , and they were forced to abandon the town .
