 On 16 November, the 2/48th Infantry Battalion, supported by the artillery of the 2/12th Field Regiment and the machine guns of the 2/2nd Machine Gun Battalion, captured Green Ridge overlooking the track, which was the designated forming-up point for the advance on Sattelberg, which began the following day.The advance got off to a bad start initially as it was hampered in the inland area by the prevalent rugged terrain which consisted largely of thick jungle and steep "razor-back" ridges.The ability of forces to manoeuvre in this environment was limited and Whitehead, the Australian brigade commander, determined to use infiltration tactics as a result.
