This distinguished officer was the son of General the first Lord Harris, and entered the army as an ensign in the seventy-sixth regiment of infantry, on the 24th of May, 1795; was promoted lieutenant in the thirty-sixth regiment on the 3rd of January, 1796, from which he was removed to the seventy-fourth Highlanders on the 4th of September following, and joined in India in 1797. Lieutenant Harris served at the battle of Mallavelly on the 27th of March, 1799, and during the campaign under his father, Lord Harris, which led to the capture of Seringapatam, and was in nearly all the affairs, out-posts, and in the storming party on the 4th of May, 1799, which carried that fortress, where Lieutenant Harris was one of the first to enter the breach, for which he was commended on the spot by Major-General (afterwards Sir David) Baird. Being sent home with the captured standards, Lieutenant Harris had the honor of presenting them to His Majesty King George III., and was promoted to a company in the forty-ninth regiment, on the 16th of October, 1800, which he joined at Jersey, and embarking with it towards the end of the year for England, was wrecked on the passage off Guernsey. Captain Harris afterwards accompanied his regiment in the expedition to the Baltic under the command of Admiral Parker and Vice-Admiral Nelson, and was present in the “Glatton” frigate in the desperate action off Copenhagen on the 2nd of April, 1801.
