​​​This area was within the German Atlantic wall defences of Stutzpunkt 82, one of many similar locations along this stretch of coastline. Further to the east of this position was Fort Lapin and the Widerstandnest (WN) 80 and 92. These German fortified strongpoints were later encountered by the Canadian forces as they pushed in towards the town of Calais.

​On 27 September the CSR observed the British Royal Air Force (RAF) targeting Cap Gris-Nez to the west, as they waited before any collective advance on Calais could be made. At 16:40 they observed the RAF drop leaflets onto Calais, but it was stated they missed their intended target due to the winds.

​At 16:00, A Company CSR, attacked Fort Lapin, located 1km east of this position. They had difficulty in removing the German defenders, so Churchill Crocodile (Flame Thrower) tanks were sent in to support them. The advance moved slowly toward Fort Lapin under machine gun and mortar fire. A Company began to clear the machine gun positions and pillboxes, one of which waving a white flag. It was deemed necessary to fight on and the white flag was not acknowledged.

​At 20:45 the position was finally secured and taken, with the German garrison surrendering to the Canadian troops. In total around 150 prisoners of war were taken. To the surprise of the Canadian troops who searched the German positions for any intelligence, they found an ample amount of food. The German troops had canned peaches and cherries, and the Canadian troops noted this was far better than their ‘Compo Stew’.

​On 28 September, the CSR continued to engage with German defenders on the edge of Calais. Within Fort Lapin there was a small German hospital in which the wounded, now prisoners of war, were being evacuated away from the fighting. The CSR pressed on right into the heart of the German defences close to WN80. At 20:00 an unofficial truce was called, however the men stated that if they were fired upon, they would immediately return fire.

​The following day at around 09:00, Canadian Major General Spry and the Commander of the German garrison, Colonel Schroeder, requested a cessation of hostilities. The German officer requested a truce to allow civilians to evacuate from Calais. This was agreed and put in place from 12:00 on 29 September to 12:00 on 30 September.​
