In the attack upon Canada there were two principal lines to be chosen,--that by the way of Lake Champlain, and that by the way of the St. Lawrence. The former was entirely inland, and as such does not concern our subject, beyond noting that not till after the fall of Quebec, in 1759, was it fairly opened to the English. In 1757 the attempt against Louisburg failed; the English admiral being unwilling to engage sixteen ships-of-the-line he found there, with the fifteen under his own command, which were also, he said, of inferior metal. Whether he was right in his decision or not, the indignation felt in England clearly shows the difference of policy underlying the action of the French and English governments. The following year an admiral of a higher spirit, Boscawen, was sent out accompanied with twelve thousand troops, and, it must in fairness be said, found only five ships in the port. The troops were landed, while the fleet covered the siege from the only molestation it could fear, and cut off from the besieged the only line by which they could look for supplies. The island fell in 1758, opening the way by the St. Lawrence to the heart of Canada, and giving the English a new base both for the fleet and army. The next year the expedition under Wolfe was sent against Quebec. All his operations were based upon the fleet, which not only carried his army to the spot, but moved up and down the river as the various feints required. The landing which led to the decisive action was made directly from the ships. Montcalm, whose skill and determination had blocked the attacks by way of Lake Champlain the two previous years, had written urgently for reinforcements; but they were refused by the minister of war, who replied that in addition to other reasons it was too probable that the English would intercept them on the way, and that the more France sent, the more England would be moved to send. In a word, the possession of Canada depended upon sea power. Montcalm, therefore, in view of the certain attack upon Quebec by the river, was compelled to weaken his resistance on the Champlain route; nevertheless, the English did not get farther than the foot of the lake that year, and their operations, though creditable, had no effect upon the result at Quebec.
