General Prideaux proceeded in the expedition against Niagara with his provincials and a body of warriors of the Six Nations, who, in spite of their treaty of neutrality, had been induced to join in this enterprise. Prideaux advanced by way of Schenectady and Oswego, and on the 6th of July effected a landing near Fort Niagara without opposition. The bursting of a gun, however, killed General Prideaux, when the command devolved on Sir William Johnson. Twelve hundred French, and an equal number of Indian auxiliaries, advancing to the relief of the garrison, gave battle to the English, and were routed with great loss, leaving a considerable number prisoners; on which the dispirited garrison capitulated. The surrender of this post cut off all communication between Canada and the south-west. Sir William Johnson having so far accomplished his object, should, according to pre-arrangement, have descended Lake Ontario, to co-operate with Wolfe on the St. Lawrence; but again the want of shipping, shortness of provisions and the incumbrance of his French prisoners, prevented his doing so. Thus disappointed in receiving these important reinforcements, Wolfe was compelled to commence the siege of Quebec alone. The presence of Wolfe had already inspired the most unbounded confidence. His army consisted of 8,000 men; his fleet, commanded by Admirals Saunders and Holmes, consisted of twenty-two ships of the line, and the same number of frigates and armed vessels. On board of one ship was Jervis, afterwards Earl St. Vincent; another had for master, James Cooke, the afterwards celebrated navigator. The brigades were commanded by Robert Moncton, afterwards governor of New York, and the conqueror of Martinique. Wolfe selected as his adjutant-general Isaac Barre, his old associate at Louisburg, an Irishman of humble birth, but brave, eloquent, and ambitious. On the 27th of June, the whole armament disembarked on the island of Orleans, just below the city. We will give a rapid account of the events of this important siege from Mrs. Willard’s excellent history.
