In the spring of 1755 the regiment embarked from Dublin, and, having landed at Liverpool, occupied quarters in England until the breaking out of the Seven Years' War, when it was embarked on board the fleet commanded by Admiral Byng, in March, 1756, to serve as marines, and sent to the Mediterranean to endeavour to preserve Minorca from the power of the French. It served at the engagement with the French fleet off Minorca on the 20th of May; but the enemy had previously landed an army, and captured the whole island excepting Fort St. Philip, and the relief of this fort was not attempted. The admiral was afterwards brought to trial and shot.
