Potts' two battalions commenced their advance along the track on the basis that 40,000 rations plus ammunition and other supplies had been stockpiled at Myola and additional supplies existed at staging points along the route. Potts arrived at Myola on 21 August to find only 8,000 rations (five days' reserve) and a further two days' reserve forward. Potts was forced to hold his force at Myola until a sufficient reserve could be accumulated—which impacted his conduct of the battle at Isurava (commencing 26 August).
