Under mounting pressure from Allen and Rowell to make a stand, Potts determined to do so at Mission Ridge, which ran northward from Brigade Hill toward the village of Efogi. Lieutenant Colonel Geoffrey Cooper, commanding the 2/27th Battalion had reached as far as Kagi with the leading companies on 4 September. Cooper then concentrated his battalion in position just south of Efogi, where he could screen the brigade before he was recalled back to the position of the main force during the afternoon of 6 September. The 2/27th occupied a forward position astride the track. The 2/14th Battalion was to its immediate rear and slightly to the east. Brigade headquarters was approximately to the rear. The main force of the 2/16 Battalion was between brigade headquarters and the forward battalions, while its D Company was located with brigade headquarters as rear protection.
