November 18, 1941, the operation "Crusader" begins. The strike of the XXX Corps of the 8th British Army aims to break into the besieged Tobruk. By using the fact that the Italians sent a part of the troops from Tobruk to counter the attack, they tried to break the lap to merge with the 8th Army. Rommel throws Sidi Rezeigh 15th and 21st Panzer Divisions in the direction of Sidi Rezeigh. The Carpathian Rifle Brigade attacks the western sector of the lap towards Acroma.
