In 1756 she joined the Mediterranean fleet and was heavily damaged at the Battle of Minorca, one of the first naval battles of the Seven Years' War, where she suffered 45 casualties. After undergoing repairs and a further refit, during which she was reduced to a 60-gun fourth rate ship of the line, "Intrepid" rejoined the Seven Years' War, taking part in the Battle of Lagos and the Battle of Quiberon Bay in 1759. She crossed the Atlantic in 1761, and fought in the West Indies Campaign of the War, featuring in the Siege of Havana the following year. She was broken up at Chatham in 1765.
