German forces reached the regimental positions on 12 April; the following day, their attempts to cross the river in assault boats were repulsed. During the evening, the regiment disengaged and fell back to Kolindros; it was attacked by German tanks and infantry on 14 April. Boys anti-tank rifles were useless against the German tanks, although Bren gun fire was effective against the German infantry. When its positions were flanked by tanks, the regiment retreated to Olympus Pass and was ordered to take up positions at Deskati Pass as a rearguard. The pass, a possible withdrawal route for the 1st Armoured Brigade, was reached on 15 April. On the 17th, division commander Major General Bernard Freyberg dispersed the regiment to screen the rear of his retreating troops. The next day, A and C Squadrons withdrew from Olympus Pass and Eleftherochorion after a German tank attack. B Squadron fought a rearguard action at Tempe, retreating down the Volos road and losing several carriers.
