In July 1779 he became commander, and was appointed to the " Rover " sloop ; in June of the following year he atttained the rank of post-captain. Soon afterwards he re-turned to England in charge of a convoy. The outbreak of the war with France gave him his first opportunity of obtaining marked distinction. Appointed first to the " Orion " and then to the " Queen " in the Channel Fleet, under the command of Lord Howe, he took part in the three days' naval engagement with the Brest fleet, which terminated in a glorious victory on the 1st June 1794.

In 1798 he commanded the " Leviathan " in the Mediterranean, and had charge of the naval detachment which, in conjunction with a military force, captured Minorca. Early in 1799 he was raised to the rank of rear-admiral, and sent to the West Indies to succeed Lord Hugh Seymour. During the voyage out he captured a valuablo Spanish convoy of eleven merchantmen. in March 1801 he was the naval connnander of the combined force which reduced the islancl5 of St Bartholomew and St 31artin, a service for which be WRS rewarded with the order of the Bath a,nd a pension of X1000 a year.

Two years later, while cruising off Cadiz with Lord Collingwood, he was detached with his squadron to pursue a French fleet that had been sent to the relief of St Doiningo. He came up with the enemy on the 6th February 1806, and, after two hours' fighting, inflicted a sismal defeat npon them, capturing three of their five ve,ssels and stranding the other two.
