French boatmen, when Sir George Prevost asked him how soon he could have his men ready to go down to Châteauguay. "As soon as they have done their dinner!" he responded. Within a few hours he had provided them with batteaux, and they were off down the rapids. When Sir George himself, who was on the way, got there, he, to his great surprise found McDonell before him. "Where are your men?" said he. "There," said the Highland Colonel, pointing to his force resting on the ground—"not a man absent."[21]

For nearly three weeks the parties of Canadian workers worked continually upon the plan of De Salaberry, while Hampton was considering, preparing, reviewing his troops, and arranging for a communication with Wilkinson so soon as the latter should have passed Ogdensburg on his way down the St. Lawrence.

On the 21st of October the advance down the Châteauguay commenced. The first move was a rapid march by General Izard with the light-equipped troops and a regiment of the line, who surprised a party of about ten[22] Indians sitting late in the afternoon at their evening meal at the junction of the Outarde and Châteauguay Rivers, and killed one of them. There Izard encamped and proceeded to establish a road of communication with Hampton. Word was soon brought to Major Henry, of the Beauharnois' Militia, commanding on the English River. Henry sent word to General De Watteville at La Fourche, and had Captains Levesque and Debartzch advance immediately with the flank companies of the 5th Battalion of embodied militia and about 200 men of the Beauharnois' division. This was the preliminary move towards the battle.

They advanced about six miles that night up the Châteauguay from La Fourche, when they came to a wood which it would not have been prudent to enter in the dark. Next morning early they were joined by De Salaberry with his Voltigeurs and the light company of Captain Ferguson, an officer who took a front place in the affair. De Salaberry brought all these companies about a league up the bank to the place he had fortified, and there stopped. An American patrol party being observed in front, General De Watteville came over himself, visited the outposts, approved of them, and the work proceeded.[23] That evening the main body of the Americans encamped at Sear's, about twenty-five miles above the Châteauguay's mouth. The engineers had cut a road for the ten cannon, and with great labor and difficulty had dragged them thus far.[24]

Within two days more Hampton's men had opened and completed a large and practicable road, which is still traceable, from his position at Four Corners twenty-four miles through the woods and morasses, and brought up his guns and stores to his new position, about seven miles from De Salaberry's. (About Dewittville?)

From this point he despatched Colonel Purdy with about 1,500 men, composed of a light brigade (the 1st Brigade of the American Army[25]) and a strong body of the infantry of the line, at an early hour in the night of the 25th, across the Châteauguay and down its right bank[26] at a bend adjoining what is now known as the Cross Farm, with orders to gain the ford and fall on the rear of Lieut.-Colonel De Salaberry's position, while the main body, under General Izard, were to commence the attack in front. Purdy's brigade crossed not far above De Salaberry, and proceeded into the woods of the opposite side. A cedar swamp, an unexpected stream in which they floundered, and the ignorance of their guides misled and bewildered them. This was the fault of Hampton, and due to his headstrongness, for the guides had protested that they did not know that side of the Châteauguay; but he had ordered them to proceed. Purdy's command became scattered, were forced to halt in confusion, and had to sleep in the open woods, cold, wet, exhausted, and apprehensive.[27] General Hampton, however, in the morning, fully expected to hear them attacking the ford, advanced, and at ten o'clock his troops appeared in sight of the party of busy woodchoppers, about 3,500 men, with three squadrons of cavalry, marching in column along the high road, commanded by General Izard. Lieut. Guy's picket fired, the workmen dropped work and ran, Guy retired upon Johnson, and both Lieutenants retreated with their men to the completed abattis, where they formed up again and began to fire smartly.

De Salaberry, on hearing the firing, promptly advanced with the light company of the Canadian Fencibles, commanded by Captain Ferguson, "flanked by twenty-two Indians on the right and centre,"[28] and two companies of his Voltigeurs, commanded by Captains Chevalier and Louis Juchereau Duchesnay. Ferguson's companies he posted on the right, in front of the abattis, in extended order, its right skirting on the adjoining woods and abattis, among which were distributed a few Abenaquis Indians. The three officers, Ferguson and the two Duchesnays, executed the movements required of them with the coolness of a day of parade. The Voltigeur company of the oldest of the Duchesnays, known as "the Chevalier," occupied, in extended order, the ground from the left of Ferguson's Company to the Châteauguay, and the company under Captain Louis Juchereau Duchesnay, with about thirty-five[29] Sedentary Militia under Captain Longtin, were thrown back along the margin of the river, hidden among the trees and bushes, so as to flank Colonel Purdy's men, or prevent him from flanking the Canadian position. Between the abattis and the front line were a company of Voltigeurs, Captain Lecuyer commanding, and beyond them on the right a light company (that of the 5th Battalion) of embodied militia with their side pickets, under Captain Debartzch; then, to the right of them, in the woods, the Indians under Captain La Mothe. There were thus in
