At dawn on 19th August, Currie’s force attacked St. Lambert without artillery support. The village was about 1000 yards long from north to south along the road D13 with houses lining its sides. The village comprised several clusters of buildings. One was at the north end where Currie placed his headquarters. The main intersection near the town hall saw heavy fighting. The church and other buildings near the two bridges over the Dives was where the Germans concentrated.
The initial advance into St. Lambert was met with fire and the lead tank was hit causing the crew to bail out. Shortly after, the crew of Currie’s tank took out a German Panzer Mk IV tank while Currie was scouting the town on foot. Infantry from the Argyll’s moved down D13 clearing the houses along the road. After six hours the force fought halfway through the village and the attack stalled. The force dug in to prepare for German counterattacks.

Some point in the afternoon a message was sent from the SAR saying “Tired and must have relief in form of inf[antry], slight enemy resistance. P[O]W still surrendering. Unless relief comes, Germans will move back in.” No relief was forthcoming, and the fighting continued. Infantry attacks continued through the rest of the day and night. Currie later recalled that at “one point late in the afternoon, the tanks were running around in circles firing at one another, to keep the Germans from climbing on top of them.” It was estimated that hundreds, possibly thousands, of Germans moved into the village during the afternoon.

Around 1800 hours, ‘C’ Company of the Argyll’s and a composite company of The Lincoln and Welland Regiment reinforced Currie’s force in St. Lambert. Arthur Bridge of the Argyll’s described the devastation in the Falaise Pocket, “Such a mess cannot be described: smashed cars, trucks, guns, tanks, wagons, horses, men in every road and field.” Currie personally led forty men of ‘C’ Company of the Argyll’s to their positions. An artillery officer was also sent to St. Lambert to direct fire on the Germans. Despite Canadian artillery rounds falling within mere yards of his own tank, Currie ordered the firing to continue due to its effectiveness on the enemy.

Currie recalled that the “Pressure from the Germans mounted again near dark, and as we were pretty well spread out, I was afraid that we might be chopped up piecemeal. I decided to draw the force in tighter for the night, so we gave up a part of the village.” Positions were taken up near the bridge, the main intersection, and by Currie’s headquarters in the north end of the village. Overnight, German troops continued to infiltrate the Canadian positions and more fighting took place. With little infantry support, the tank crews were effectively blind and fired into the darkness at any noise they heard.
