Yet the persistence of the English was at length to have its way. In 1720 the walls of Quebec were enlarged and made mightier, and the citadel, largely in the form in which it exists to-day, was erected. Vaudreuil, the last governor of New France, loudly proclaimed that the city was impregnable. In 1759 came the expedition of Wolfe against Quebec, the final outcome of which and the method of attack, with Wolfe’s heroic death on the Plains of Abraham, is a story that every schoolboy knows. This conflict was the first in which the citadel took part. The mighty works in which Vaudreuil trusted so loudly had been overcome on their first trial, while the high-perched, precariously-placed little “Castle,” which Champlain had first built and which his successors had altered to suit their times, had withstood innumerable Indian attacks and had seen three assaults by Europeans fail against it. The spirit of the men who manned the forts had changed with their times. There is another tale of siege and Quebec which is not widely familiar and yet which all Americans should know. It is the story of Montgomery’s expedition during the Revolution--an expedition in which he lost his life and in which Benedict Arnold played a conspicuous part. Richard Montgomery was a lieutenant in Wolfe’s army and was thoroughly familiar with Quebec. At the outbreak of the War of Independence he was deputized to lead an army up the Hudson and by the familiar approach along the Richelieu River and the St. Lawrence to Quebec. Benedict Arnold led another force through the tangled forests of northern Maine and New Hampshire, reaching Quebec ahead, even, of Montgomery. The combined forces laid siege to the city through the winter, and in the most desperate assault of all, one in which Wolfe’s feat of scaling the cliff was attempted, Montgomery lost his life. After six months the United States troops departed, confessing failure. From that time to this the military history of Quebec has been uneventful. In the early part of the nineteenth century old Castle St. Louis, which had stood so many storms and assaults, succumbed to fire. The site is now an open square with some relics and a fine view over the river. The great citadel of Quebec rises three hundred and fifty feet above the river and covers nearly forty acres. The portion of the works overlooking the St. Lawrence is called the Grand Battery, while the surmounting pinnacle of the citadel is known as the King’s Bastion. From the King’s Bastion a most glorious panorama is spread out before one, embracing the city, the great river, hundreds of miles of forest and farm land, the Laurentian mountains in the distance in one direction and the green hills of Vermont far away in another. All of the old works of Quebec have been retired from active service in a military sense. The city is protected by modern fortifications in other quarters.
