The operations in which the expenditure of ammunition took place--alluded to by Colonel Harding--were prior to the investment of Copenhagen, and were conducted by Sir A. Wellesley with complete success. During their progress, a very gallant Artillery officer, Lieutenant Lyons, was killed by a 3-pounder shot, from a gun which had been placed by the enemy on the Copenhagen road. On account of the facilities offered by the coast, and a continuance of fine weather, the Danish gun-boats took part in these operations. The conduct of the Royal Artillery was thus mentioned by [Sidenote: Sir A. Wellesley to Lord Cathcart, Kioge, 29 Aug. 1807.] Sir Arthur Wellesley:--“I cannot close this letter without expressing to your Lordship my sense of the good conduct of the troops. All conducted themselves with the utmost steadiness; but I cannot avoid to mention particularly the British Artillery under the command of Captain Newhouse.” From the 21st August to the 1st September, the Artillerymen were employed in making and arming the batteries necessary for the bombardment. The distribution of these batteries when the bombardment commenced, on the 2nd September, was as follows:-- [Sidenote: MS. Official Returns, and Gen. Blomefield’s Diary.] No. of Guns. Nature.
