In adding the following memoir of this distinguished officer, who is a younger brother of the late noble Lord, we feel confident that it will be read with interest, his services having been in some degree mixed up with those of his illustrious brother, in the prosecution of the American and the late Continental war. The author having been intimately acquainted with Sir Thomas, and having for many years kept up a constant correspondence with him, has peculiar satisfaction in discharging this duty of gratitude to a friend for whom he had always the highest regard and respect, and to whom he materially owes his advancement in the profession to which he has the honour to belong. Lieutenant General Sir Thomas Saumarez entered the army in January 1776, at the early age of 15 years, when he purchased a second lieutenancy in the 23rd regiment or Royal Welsh Fusiliers. He was at the taking of New York Island, and assisted at the storming of Fort Washington and in capturing 3300 men. In April 1777, he embarked on board transports with the regiment, and proceeded to destroy all the military stores and provisions the enemy had collected at Danburg in the province of Connecticut. He first distinguished himself in the action fought at this place, and in the actions of Ridgefield and Compo Point. Having obtained a lieutenancy in 1778 without purchase at Philadelphia, he soon after was selected to serve in the company of grenadiers which was then attached to the brigade, composed of more than fifty companies of grenadiers. He was in the severe action fought at Monmouth, in the Jerseys, when the captain, and more than one-third of the company to which he belonged, were killed or wounded. His services were volunteered with the regiment to serve as marines on board Lord Howe's fleet, destined to attack the French fleet, under Count D'Estaing, at Rhode Island, very superior in size and weight of metal to the British: a dreadful storm arose when the two fleets were within gun-shot of each other, which prevented the engagement. In 1779, he embarked and went up Hudson's River to East Chester, and Ver Plank's Point, and was at the attack of Fort La Fayette and other fortified places, which surrendered.
