led to the operations that resulted in the surrender of the place without a shot being fired. For this service he received the warm thanks of Lieut.-General Hutchinson, who assumed the command upon the death of General Abercromby, and also the approbation of His Royal Highness the Duke of York, Commander-in-Chief. In 1803 Captain Doyle returned from the Mediterranean, was appointed Major of Brigade under Lieut.-General Sir James Henry Craig, K.B., by whom he was employed, with other staff officers, to make separate reports of the best mode of defence of Hosely Bay; his plan was highly approved by Sir James Craig, who recommended him to the Commander-in-Chief, and he was promoted to the rank of Major of the second battalion of the Sixty-first regiment, on the 9th of July 1803. In the following year Major Doyle commanded a corps composed of light infantry companies, and of regiments of volunteers, formed for the defence of the northern coasts of England by Lieut.-General Sir Hew Dalrymple, whose warm thanks he received. At the close of 1804 he was appointed by General Sir David Dundas, K.B., to command a corps of light infantry at Barham Downs, where he received the thanks of the Adjutant-General for his system of light infantry practice, and about the same time his Military Catechism was published. He was appointed Assistant Quartermaster-General at Guernsey, and on the 22nd of August 1805 was promoted to the rank of Lieut.-Colonel of the EIGHTY-SEVENTH regiment. He received the thanks of the Governor of Plymouth, of the Royal Court of Guernsey, and of the Commander-in-Chief, for the exemplary conduct of both battalions of the EIGHTY-SEVENTH, each having been under his command. In 1808 he was sent into Spain by His Majesty’s Government as a Military Commissioner.
