With the western flank threatened, the Australian force at Isurava withdrew to a position at the Isurava resthouse (between Isurava and Alola) during the late hours of 29 August. On 30 August, the 3/144th attacked from the western flank and cut the route rearward to Alola. The attack was preceded by intense fire from the Japanese mountain artillery. At 3:00 pm, Potts order a withdrawal to Eora Village. Many members of Maroubra Force became separated including Lieutenant Colonel Arthur Key, who was subsequently captured and killed. In his post-operation report, Potts noted: "At no time were 2/14th and 2/16th Australian infantry battalions ever intact and available for a concerted operation, wholly and solely due to the delays occasioned by supply."
