After days of probing reconnaissance, a Brigade assault took place on the night of 11/12 June in which the Commando's task was to secure Mount Harriet on the Brigade right flank. By moonlight and in freezing temperatures, 42 Commando moved undetected through enemy minefields in a right-flanking movement to surprise the enemy in their rear. Consecutive assaults by "K" and "L" Companies followed, up steep slopes onto company positions. Against strong resistance and continuous artillery bombardment, the Marines prevailed. By first light more than 30 enemy had been killed and over 300 prisoners taken as 42 Commando consolidated on Mount Harriet. 42 Commando suffered two fatalities themselves – one on Mount Harriet and one on Wall Mountain.
