Following the outbreak of the
American Revolutionary War, Berkeley served on
HMS Victory, in which he commanded a gundeck at the
First Battle of Ushant. Berkeley became a prominent opponent of
Sir Hugh Palliser after the battle, at which Palliser was
accused of refusing to obey the orders of his commanding officer, Admiral
Augustus Keppel. This opposition did not prevent Berkeley gaining his first independent command the same year, when he took over the 8-gun HMS
Pluto. The next year he moved to the similarly tiny HMS
Firebrand and impressed his commanding officer
Lord Shuldham. Shuldham's recommendation for promotion was turned down however due to his previous involvement in the Palliser affair. In 1780, Berkeley was appointed to HMS
Fairy, a 14-gun
brig under his cousin
George Keppel and together they captured the American ship
Mercury, taking prisoner
Henry Laurens who was on a secret mission to loan money from the Dutch government. The information procured from Laurens led to a British declaration of war against the
Netherlands. As another consequence, Berkeley was promoted to captain by Admiral
Richard Edwards and commanded
Fairy during the relief of the
Great Siege of Gibraltar and further operations against American shipping from Newfoundland. In 1781, Berkeley was given command of the frigate
HMS Recovery which was placed in the squadron of
Samuel Barrington. At the
Second Battle of Ushant in 1782, Berkeley's ship was engaged in the decimation of a French convoy and its escorts. As a reward, Berkeley was given the captured
ship of the line HMS Pegase. Whilst aboard her he was approached by a young
William Cobbett who wanted to volunteer for the navy. Berkeley dissuaded Cobbett, who later credited Berkeley with saving him from "most toilsome and perilous profession in the world". In April 1783, Berkeley finally gained a seat in parliament, at the constituency of
Gloucestershire. Berkeley would remain MP for the town for the next 27 years and took the position seriously, becoming a very important independent MP. He even attempted to bring
William Pitt the Younger and
Charles James Fox into an alliance, although the collapse of the scheme ended with a feud between him and Fox. ) The following year, 1784 after the peace, Berkeley married Emilia Charlotte Lennox, daughter of
Lord George Lennox. The marriage was a love match and Berkeley's sister commented that they were "a pattern of domestic happiness scarcely to be equaled". The couple had three daughters and two sons and remained an unusually tight-knit family, Berkeley using his extensive personal wealth to bring his family with him on long voyages and overseas postings. In 1786 Berkeley commanded
HMS Magnificent and remained with her for three years until 1789 when he became surveyor-general of the ordnance. He left the post after the
French Revolutionary Wars broke out in 1793, taking over
HMS Marlborough. ==French Revolutionary Wars==
