In the Seven Years' War Hood fought at the Battle of Quiberon Bay on 20 November 1759, and in 1761 Minerva recaptured after a long struggle, the 60-gun of equal force, which had been captured by the French in 1756. For the remainder of the war, from 1761 to 1763, he was captain of in the Mediterranean.
From this time forward Hood was in continuous employment afloat and ashore. In 1778 he was appointed to and fought at the First Battle of Ushant on 22 July. In the court-martial of Admiral Augustus Keppel that followed the battle, although adverse popular feeling was aroused by the course which Hood took in Keppel's defence, his conduct does not seem to have injured his professional career. In 1780 Hood was promoted to Rear Admiral of the White, and succeeded Kempenfeldt as one of Howe's flag officers. In the American Revolutionary War, in, he took part in Howe's relief of Gibraltar in 1782.
Hood served in the House of Commons for a time. Promoted vice-admiral in 1787, he became Knight Companion of the Bath in the following year, and on the occasion of the Spanish Armament in 1790 flew his flag again for a short time. On 22 October 1790 he was a member of the court that acquitted William Bligh of losing his ship. On the outbreak of war with France in 1793 he went to sea again. In the War of the First Coalition, on 1 June 1794, in , he was third in command to Admiral Lord Howe at the battle of the Glorious First of June. For his exploits in this battle he was elevated to the Irishpeerage as Baron Bridport and received the large Naval Gold Medal and chain. Henceforth Hood was practically in independent command. On 23 June 1795, with his flag in Royal George, he fought the inconclusive Battle of Groix against the French under Rear Admiral Louis Thomas Villaret de Joyeuse off the Île de Groix and captured three ships. He was much criticized in the navy for his failure to win a more decisive victory. However the British public considered the battle a great victory and his peerage was made English and he was promoted to Vice-Admiral of Great Britain. From 1795 until Hood's retirement in 1800, he was commander of the Channel Fleet. In 1796 and 1797 he directed the war from, rarely hoisting his flag afloat save at such critical times as that of the Irish expedition in 1797. He was about to put to sea when the Spithead fleet mutinied. He succeeded at first in pacifying the crew of his flagship, who had no personal grudge against their admiral, but a few days later the mutiny broke out afresh, and this time was uncontrollable. For a whole week the mutineers were supreme, and it was only by the greatest exertions of the old Lord Howe that order was then restored and the men returned to duty. After the mutiny had been suppressed, Hood took the fleet to sea as commander-in-chief in name as well as in fact, and from 1798 he personally directed the blockade of Brest, which grew stricter and stricter as time went on. In 1800 he was relieved by John Jervis, 1st Earl of St Vincent.
Retirement & death
In reward for Hood's fine record his peerage was made a viscounty. He spent the remaining years of his life in retirement and died on 2 May 1814. The viscountcy in the English peerage died with him; the Irish barony passed to the younger branch of his brother's family, for whom the viscountcy was re-created in 1868.
Marriages
He married twice, but failed to produce any issue:
