After a military education, Cole first saw active service at Martinique, where he was aide-de-camp to Sir Charles Grey. He was deputy adjutant-general and aide-de-camp to the commander-in-chief in Ireland in 1797, when he was returned for the family borough of Enniskillen. In May 1799 he attempted to vacate his seat in favour of his brother-in-law Balfour who, however, opposed the Union: Lord Cornwallis was prepared to resist, but was persuaded by the Duke of Portland to accept the resignation, though it was conveniently postponed until 18 Jan. 1800.
In December 1804 Cole was absent from Parliament and due shortly to proceed to Malta, to assume the command there, though he was in the House on 18 Feb. 1805. From Malta he proceeded to Sicily, distinguishing himself in action at Maida. In his absence and on the understanding that Lord Enniskillen was friendly to them, government supported him in the contest for Fermanagh in 1806, though if unsuccessful he would have fallen back on the borough of Enniskillen.
The House’s acknowledgment of his gallant services on four occasions was delayed: in July 1814 he presented himself to the Speaker ‘on the very day of the prorogation, which was an impossible time’. Despite a reminder from the Speaker, Sir Lowry neglected to present himself again for so long that Castlereagh’s intervention was at length necessary to secure the vote of thanks to him, 20 May 1816.
At the time when he received the House’s thanks for his services, Cole appeared in the government divisions on the civil list, 6 May, and on public revenue, 14 and 17 June 1816, as well as in the majority against Catholic relief, 21 May. He was again in a government majority on 7 Feb. 1817, but he seems to have been on duty in France thereafter until the dissolution. He reappeared in the ensuing Parliament, voting against Catholic relief, 3 May 1819, and with ministers on Tierney’s censure motion, 18 May, as well as speaking for the retention of corporal punishment in the army, 15 Mar. Meanwhile he had accepted a military government at home. In 1820 he was reported to have forfeited another (that of Sheerness) by taking the Queen’s part in the division lobby.
Cole was commended while in the Peninsula for his ‘very polished manners and great charm’. He was ‘very warm hearted and sincere’ and ‘a keen soldier and would go to the end of the world in pursuit of his profession. He is also an excellent mechanic, has very good taste and understands better than anyone how to keep a comfortable ménage.’ Of himself he admitted in 1814, ‘I am convinced nature never intended me for a public character’.
