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. 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 again 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; was employed as Envoy and Ambassador to the courts of Portugal and Russia; and died at Twickenham on the 13th of July, 1773. JOHN BROWN. _Appointed 1st April, 1743._ This officer entered the army as Cornet of horse on the 5th of August, 1704, and served several campaigns on the continent in the army commanded by John Duke of Marlborough.
