After his return to England, he was re-appointed an Assistant Adjutant-General on the Staff of Great Britain, and subsequently to be Assistant Military Secretary to His Royal Highness the Duke of York, as Commander-in-Chief. In the month of July, 1808, he embarked with the expedition for Portugal, under the orders of Lieutenant-General Sir Arthur Wellesley, and was present at the battles of _Roleia_ on the 17th of August, and of _Vimiera_ on the 21st of August, 1808, for which he received a medal struck for the purpose of commemorating those victories, and of distinguishing the officers engaged in them: he received also from the Portuguese Regency the Chivalric Order of the Tower and Sword. These victories led to the Convention of Cintra, and to the consequent evacuation of Portugal by the French army under Marshal Junot, Duke of Abrantes. Lieutenant-Colonel Torrens returned to England with Sir Arthur Wellesley about the end of the year 1808, and resumed his former situation as Assistant Military Secretary to His Royal Highness the Duke of York; he was promoted to be his Military Secretary on the 2d of October, 1809. He was appointed from the Eighty-ninth Regiment to a company in the Third Foot Guards on the 13th of June, 1811, and Aide-de-camp to the Prince Regent, with the rank of Colonel, on the 20th of February, 1812. He was promoted to the rank of Major-General on the 4th of June, 1814, and in the new arrangement and extension of the Military Order of the Bath in 1815, he was enrolled in the honourable list of Knights Commanders: he was appointed to the Colonelcy of the Second Garrison Battalion on the 5th of April, 1815; removed to the Royal African Colonial corps on the 27th of November, 1815, removed to the Second West India Regiment on the 21st of September, 1818, and on the 26th of July, 1822, he was promoted to the SECOND, or QUEEN'S ROYAL; on the 25th of March, 1820, he was appointed from the situation of Military Secretary to that of _Adjutant-General to the Forces_. During the period of his employment as Military Secretary, in which the most active operations of the late war took place, the labours of his office were excessive, and his health became affected; yet his exertions were never lessened, and after his appointment as Adjutant-General, he undertook, with considerable labour and zeal, the revision of the '_Regulations for the Exercise and Field Movements of the Infantry of the Army_,' and, with the authority of His Majesty King George IV., engrafted in them the alterations and improvements which had been introduced and practised by different Commanders during the late war. The death of Sir Henry Torrens took place suddenly, on the 22d of August, 1828, while on a visit to his friend Mr. Johnes Knight, at Welwyn, Herts., where his remains were consigned privately to a grave in the church of that parish.
