ARCHIBALD HAMILTON entered the army in November, 1688, and at the Revolution he adhered to the Prince of Orange, afterwards King William III, under whose command he served in Flanders. In the reign of Queen Anne, he served in Portugal and Spain, and his regiment (Montjoy's foot), was nearly annihilated at the battle of Almanza in 1707, where he was taken prisoner. This corps was subsequently incorporated into other regiments, and the officers sent home to recruit, and at the peace of Utrecht it was disbanded. In the summer of 1715, he was appointed Lieut.-Colonel of the eleventh dragoons, and in May, 1732, he was promoted to the colonelcy of the twenty-seventh foot: from which he was removed, in 1737, to the FOURTEENTH dragoons. He died in 1749. JAMES LORD TYRAWLEY. _Appointed 24th July, 1749._ THE HON. JAMES O'HARA was appointed lieutenant in the royal regiment of fusiliers, commanded by his father, on the 15th of March, 1703, and in 1706 he proceeded with his regiment to the relief of Barcelona. In the following year he served on the staff of the army in Spain, and was wounded at the battle of Almanza, where, it is said, he was instrumental in saving the Earl of Galway's life. He served several years at Minorca, and, in 1713, obtained the colonelcy of the royal fusiliers in succession to his father, at whose decease, in 1733, he succeeded to the dignity of BARON TYRAWLEY. The rank of brigadier-general was conferred on his lordship on the 23rd of November, 1735; that of major-general on the 2nd of July, 1739; and in August of the latter year, he was removed from the royal fusiliers to the fifth horse, now fourth dragoon guards. In March, 1743, he was promoted to the rank of lieutenant-general, and in the following month obtained the colonelcy of the second troop of horse grenadier guards, from which he was removed, in 1745, to the third troop of life guards, which gave him the privilege of taking the court duty of Gold Stick. In 1746, when King George II. had resolved to disband the third and fourth troops of life guards, his lordship was removed to the tenth foot; he was removed, in 1749, to the FOURTEENTH dragoons; in 1752, to the third dragoons; and in 1755, to the second, or Coldstream regiment of foot guards. He was appointed Governor of Portsmouth on the 1st of May, 1759, and was promoted to the rank of General on the 7th of March, 1761. He held the appointment of Governor of Minorca for several years, and was employed as envoy and ambassador to the courts of Portugal and Russia. He died at Twickenham on the 13th of July, 1773.
