The army of the north was sent once more against Montreal and Quebec, this time in two divisions, the first of which was to march northward from Albany, and at Châteauguay to effect a junction with the second division, coming down the St. Lawrence in three hundred boats from Sackett's Harbor. The St. Lawrence army, commanded by General Wilkinson, was intercepted by a force of French Canadians, and sustained a memorable defeat at Chrystler's Farm, near Long Sault Rapids; and the force from Albany was now to meet a similar fate. Late in September this first division, under General Hampton, crossed the Canadian frontier south of the historical outpost of Isle-aux-Noix; but as De Salaberry was once more in command of the advanced line of defence, again holding a strong position at Blairfindie, the enemy, in order to effect the necessary junction with the other division, was compelled to make a long detour by way of the Châteauguay River. In spite of the difficulties of the route, they pressed forward towards the shore of Lake St. Louis. De Salaberry was not dismayed by this new movement, and hastening westward from Blairfindie, he ascended the Châteauguay and took up a strong position on ground intersected by deep ravines. The same tactics which had destroyed Braddock's legion at Monongahela in 1775, were now brought to bear with equal effect upon the Americans themselves. The Canadian general, having destroyed the bridges, erected a triple line of defence, under cover of which he held his force, consisting of only three hundred Canadians, a band of Indians, and a few companies of Highlanders. Early in the morning of October 26th, the American army advancing to the ford, the banks of the river suddenly blazed with musketry fire. For four hours the invaders strove in vain to force the passages of the river in the face of De Salaberry's death-dealing trenches, bravely attempting to outflank the Voltigeurs; but before those unyielding breastworks, numbers and impetuosity were both unavailing; and, at last, after heavy losses, Hampton was constrained to recall his men and retire from the field. This victory, nobly fought and won by the French Canadians, ranks with Carillon in the annals of the Lower Province, and the bullet-riven flags of both engagements are still shown among the trophies of Quebec. The loyalty and courage of the French population had decided the issue of another campaign in favour of Great Britain. [Illustration: A BEGGAR OF CÔTE BEAUPRÉ]
