 The squadron retrieved all of the remaining Tetrarchs and advanced to the south of the landing zone to link up with the rest of the regiment ; there , they received orders to support the 8th Parachute Battalion in the Bois de Bavent area and conduct reconnaissance duties . After linking with the battalion , the squadron began reconnoitring , and engaged German infantry and armour they encountered . By the end of 7 June , two Tetrarchs had been lost to enemy action , one destroyed by a German self @-@ propelled gun and the second by hitting a mine . The division was reinforced by British troops who were advancing from the invasion beaches and it began to push through Normandy , while the squadron continued its reconnaissance duties . At this time , Gale decided to avoid , when possible , engaging the Tetrarchs with German armour , as they proved to be completely outclassed by the German tanks and self @-@ propelled guns , such as the Panzer IV and the Sturmgeschütz III . Instead , when the division required armoured support , it summoned it from armoured units outside the division , and the Tetrarchs were used to support infantry patrols and provide fire support . By August , in the division 's preparation for the planned breakout from the Normandy bridgehead , the majority of Tetrarchs in ' A ' Squadron were replaced with Cromwell fast cruiser tanks ; only three Tetrarchs remained , assigned to the Headquarters troop of ' A ' Squadron .
