This officer entered the army in the reign of King James II., and at the Revolution in 1688 he joined the Prince of Orange, who promoted him to the lieut.-colonelcy of the Sixteenth regiment, with which corps he served in the Netherlands, and acquired the reputation of a brave and skilful officer. He served at the battles of Steenkirk and Landen, and at the siege of Namur; and was rewarded, in 1697, with the colonelcy of the TWENTY-FIRST FUSILIERS. He served under the great Duke of Marlborough in 1703, and in 1704 he commanded a brigade at the battles of Schellenberg and Blenheim; on the last-mentioned occasion his brigade led the attack on the village of Blenheim, and he headed his own regiment with distinguished gallantry, advancing up to the enemy's palisades before he gave the word "fire." In a moment afterwards he was shot, and thus closed a life of honor with a death of glory. His valour has rendered his name immortal in the history of his country. JOHN, VISCOUNT MORDAUNT. _Appointed 25th August, 1704._ JOHN, VISCOUNT MORDAUNT, son of Charles, Earl of Peterborough, was an officer in the first regiment of Foot Guards, in which corps he rose to the rank of captain and lieut.-colonel. He evinced great gallantry at the battle of Schellenberg, where he headed fifty grenadiers, at the storm of the enemy's works, and of that number, only himself and ten grenadiers escaped. At the memorable battle of Blenheim, he lost his left arm. His services were rewarded with the colonelcy of the TWENTY-FIRST FUSILIERS, from which he exchanged to the Twenty-eighth regiment; but on the death of Major-General de Lalo, who was killed at the battle of Malplaquet, in 1709, Viscount Mordaunt was re-appointed to the TWENTY-FIRST regiment. He was promoted to the rank of brigadier-general on the 1st of January, 1710; and died of the small-pox in April following. SAMPSON DE LALO. _Appointed 26th June, 1706._ SAMPSON DE LALO was a French gentleman of the Protestant religion, whom the Edict of Nantes forced to quit his native country. He found an asylum from persecution in England, and entering the British army, proved an efficient and meritorious officer. After a distinguished career of service in the subordinate commissions, he was appointed lieut.-colonel of the Twenty-eighth regiment, and was promoted to the colonelcy of the same corps, in February, 1704; in June, 1706, he exchanged to the TWENTY-FIRST FUSILIERS. He commanded a brigade under the great Duke of Marlborough, served at several battles and sieges, and was promoted to the rank of major-general in January, 1709. During the siege of the castle of Tournay, he was nominated by the Duke of Marlborough to negotiate the terms of capitulation with the governor. He evinced great gallantry at the battle of Malplaquet, where he was mortally wounded. In the Annals of Queen Anne it is stated, that "he was in great favor and esteem in the British army."
