 Fifty minutes later , the lead elements of the 2 / 48th Battalion entered the main mission complex , which was found to be quite badly damaged . Finally , at 10 : 00 am , upon the insistence of the 2 / 48th Battalion 's commanding officer , Lieutenant Colonel Robert Ainslie , Derrick was given the honour of raising the Australian flag over the mission , signifying that the battle had come to an end . Shortly after this , the tanks finally reached the 2 / 24th Battalion , and the 2 @,@ 200 feature was also captured . Upon completion of the flag @-@ raising ceremony , a company from the 2 / 48th moved on to the 3 @,@ 200 feature , which had also been abandoned , while further to the west , the 2 / 23rd , along with the 2 / 4th Commando Squadron cleared Mararuo and in the process found evidence that the Japanese had withdrawn towards Wareo .
