The siege of Louisbourg, in 1758, has a threefold interest to the military reader; in connection with the conspicuous services of the Royal Artillery on the occasion; in relation to the story of the gallant Wolfe, who acted as one of the Brigadiers; and in the fact that this was the last place held by the French against England, on the east coast of America. Ghastly for France as the results of the Seven Years' War were, perhaps none were felt more acutely than this loss of Canada, with its episodes of Louisbourg and Quebec. Louis the Well-beloved was sinking into a decrepit debauchee; and in the East and in the West his kingdom was crumbling away. The distinctive characteristics, even at this day, of the French population of Canada, which have survived more than a century of English rule, give an idea of the firm hold France had obtained on the country; and the strength of that hold must have made the pang of defeat proportionately bitter. Lord Loudon was to have commanded the expedition; and in 1757 the necessary troops and ships were concentrated at Halifax, now the capital of Nova Scotia. But on learning that there were 10,300 of a garrison in Louisbourg, besides fifteen men-of-war and three frigates, he abandoned the idea of an attack, and sailed for New York, leaving garrisons in Halifax and Annapolis. In the following year, the idea was revived; and General Amherst left Halifax for Louisbourg with a force of 12,260 men, of whom 324 belonged to the Royal Artillery. The naval force consisted of 23 ships of the line and 18 frigates; and the number of vessels employed as transports was 144. The Artillery train included 2 Captain-Lieutenants, 6 First Lieutenants, 5 Second Lieutenants, and 4 Lieutenant-Fireworkers; besides a staff consisting of a Colonel, an Adjutant, a Quartermaster, and two medical officers. There were no less than 53 non-commissioned officers, to a total rank and file of 63 gunners and 163 matrosses. The Regiments engaged were as follows:—the 1st Royals, 15th, 17th, 22nd, 28th, 35th, 40th, 45th, 47th, 48th, 58th, two battalions of the 60th Royal Americans, and Frazer's Highlanders. There were eleven officers of miners and engineers, and they were assisted during the siege, and at the demolition of the fortifications, by selected officers from the Infantry Regiments. General Amherst was assisted by the following Brigadiers:—Whitmore, Lawrance, and James Wolfe. The following guns were taken with the Artillery:— Brass. 26 24-prs. guns. 18 12-prs. guns. 6 6-prs. guns. 1 3-pr. gun (sent by mistake). 2 13-inch mortars. 2 10-inch mortars. 7 8-inch mortars. 10 5½-inch mortars. 30 4⅖-inch mortars.
