This corps of observation proceeded under the escort of a small division of gun-boats, commanded by Captain Mulcaster, R.N., in pursuit of the enemy; and on the 8th came up with them at Point Iroquois. General Wilkinson had on the preceding day directed Colonel Macomb to land on the British shore with 1,200 men, in order to clear the coast to the head of the Long Sault, of the militia along the shore, from various parts of the country. On the 18th this division was reinforced by Brigadier-General Brown's Brigade, with a body of dragoons from the American shore. On arriving at the head of the Long Sault, the whole of the effective men, except such as were required to navigate the boats down the Rapids, were landed under the orders of Brigadier-General Boyd, who was to proceed down the land in the rear of General Brown's division to the foot of the Long Sault.
On the 10th Lieutenant-Colonel Morrison, with his gun-boats, visited the American post at Hamilton, where he landed and took possession of a considerable quantity of provisions and stores belonging to the American army, with two pieces of ordnance. Lieutenant-Colonel Harvey, in the meantime, followed up the enemy, who in the evening were observed advancing from the woods in considerable numbers, with a body of cavalry; but upon receiving a few rounds from three field-pieces fell back for the night. (Some smart cannonading took place in the meantime between the British and American gun-boats.)
Battle of Chrystler's Farm.—On the ensuing day, Lieutenant-Colonel Morrison pressed so closely upon the rear of General Boyd's division as to compel him to concentrate his forces and give battle. The enemy's force, consisting of two brigades of infantry and a regiment of cavalry, amounting to between three and four thousand men, moved forward about two o'clock in the afternoon from Chrystler's Point, and attacked the British advance, which gradually fell back to the position which had been selected for the detachment to occupy—the right resting on the river, and the left on a pine wood, between which there were about 700 yards of open ground, the troops on which were thus disposed:
The flank companies of the 49th Regiment, the detachment from the Canadian regiment, with one field-piece, under Lieutenant-Colonel Pearson, on the right, a little advanced on the road. Three companies of the 89th Regiment, under Captain Barnes, with a gun, formed in echelon, with the advance on its left supporting it. The 49th and the 89th, thrown more to the rear, with a gun, formed the main body and reserve, extending to the woods on the left, which were occupied by the Voltigeurs under Major Herriot, and the Indians under Lieutenant Anderson.
At about half past two the action became general, and the enemy endeavoured, by moving forward a brigade from his right, to turn the British left, but was repulsed by the 89th Regiment forming en potence with the 49th Regiment, and moving forward in that direction, in echelon, followed by the 89th. When within half musket shot, the line was formed under a heavy but irregular fire from the enemy. The 49th was directed to charge the American guns, posted opposite the Canadian guns, but it became necessary, when within a short distance of them, to check this forward movement in consequence of a charge from the American cavalry on the right, lest they should wheel about and fall upon the rear; but they were received in so gallant a manner by the companies of the 89th under Captain Barnes, and the well-directed fire of the artillery, that they quickly retreated; and by a charge from those companies one gun was gained. The enemy immediately concentrated their force to check the British advance, but such was the steady continuance and well-directed fire of the troops and artillery that about half-past four they gave way at all points from an exceeding strong position, endeavouring by their light infantry to cover their retreat, who were soon driven away by a judicious movement made by Lieutenant-Colonel Pearson.
The British detachment for the night occupied the ground from which the enemy had been driven.
This (called the Battle of Chrystler's Farm, from the ground on which it occurred) is, in the estimation of military men, considered the handsomest affair during the war, from the professional skill displayed in the course of the action by the adverse commanders; and when we consider the prodigious preparations of the American Government for that expedition, with the failure of which their hopes of conquest banished, the battle of Chrystler's Farm may be classed as an event of the first importance in the defence of the Canadas.
The American division, after leaving the field, re-embarked in haste, while the dragoons, with five field-pieces of light artillery, proceeded down towards Cornwall, in the rear of General Brown's division, who, unaware of the battle of Chrystler's Farm, had continued his march for that place.
The loss of the enemy, by their own statements, amounted to three officers and ninety-nine men killed, and sixteen officers and one hundred and twenty-one men wounded. The loss of the British amounted to three officers (Captain Nairne of the 49th Regiment, and Lieutenants Lorimier and Armstrong), and twenty-one men killed, and one hundred and thirty-seven wounded, and twelve missing.
General Wilkinson, who, during the action, lay confined to his barge from a protracted illness, in his official despatch to his Government, bears strong testimony to the loyalty of the inhabitants on the Canada side of the St. Lawrence, and to the bravery and discipline of the troops he had to contend with at Chrystler's Farm.
