 The following morning , at first light , spurred on by the example provided by 11 Platoon , reinforcements from the 2 / 48th came up to complete the capture of Sattelberg . Just after dawn , a heavy artillery barrage was brought down on the summit by Australian artillery in preparation for the final attack . At 8 : 25 am patrols were sent out from ' B ' Company , 2 / 48th Battalion , and they subsequently reported that the Japanese had abandoned the position sometime during the night . Indeed , it was later established that Miyake , who had been in command of the troops gathered around the mission and had been given permission to abandon Sattelberg if the situation became untenable , had decided to withdraw from the position soon after Derrick 's attack .
