In the year 1809 Colonel Murray was appointed Quarter-Master General to the army under Lieut.-General Sir Arthur Wellesley, but returned home in 1811, and in May of the following year was appointed Quarter-Master General in Ireland, where he remained until September, 1813, when he again proceeded to the Peninsula, and served there at the head of the Quarter-Master General's department until the close of the war, participating in all the important operations of that eventful period, and evincing all the talents which are indispensable in a staff officer with an army employed in such arduous and trying circumstances: he received a Cross and five Clasps for his services in the field. In June, 1814, Major-General Sir George Murray was appointed Adjutant-General to the army in Ireland, a situation which he vacated in December following for the purpose of undertaking the governorship of the Canadas; but on the resumption of hostilities in the spring of 1815, he quitted America for the purpose of joining his former companions in arms. He did not, however, succeed in reaching the army until the allies had entered Paris; but he continued to serve on the Continent, with the local rank of Lieut.-General, until the return of the Army of Occupation to England, in 1818. In August, 1819, Lieut.-General Sir George Murray was appointed Governor of the Royal Military College; in March, 1824, he was nominated Lieut.-General of the Ordnance, and in March, 1825, he proceeded to Dublin as Lieut.-General, commanding the forces in Ireland, where he remained till the year 1828, and in September, 1829, he received the appointment of Governor of Fort George in North Britain. Sir George Murray's career was not, however, limited to his military employments. Having sat in two successive Parliaments as member for his native county of Perth, he was offered the seals of office as Secretary of State for the Colonial Department, which he accepted, and held from 1828 to 1830. His merits and talents, whether in a military or political point of view, were thus kept in view by the Duke of Wellington, then Prime Minister. In 1834 and 1835 he filled the situation of Master-General of the Ordnance, and in 1841 that appointment was again conferred upon him, and he continued to hold it till within a short period of his decease, which occurred on the 28th July, 1846. Sir George Murray was successively Colonel commandant of a battalion of the 60th Regiment, Colonel of the 72nd Regiment, and of the 42nd Royal Highlanders, which he held upwards of twenty years, when he was removed to the Colonelcy of the FIRST, OR ROYAL REGIMENT, in December, 1843.
