On 5 October, Blamey wrote to MacArthur in "hard terms" of the logistical difficulties faced by NGF and specifically, Allen. Despite this, Blamey and MacArthur pressured Allen to increase his rate of advance and Blamey forced the issue by only arranging for supplies to be dropped at Myola—effectively forcing Allen to advance to meet his point of supply. Anderson discusses this and identifies it as an "extremely risky" strategy. Blamey (and Herring) wanted Allen to maintain pressure on the retreating Japanese and push home the advantage. Dropping supplies forward maintains the momentum of advance but this quickly breaks down if the advance is stalled and there are limited reserves. The position of Blamey was premised on the proposition that the Japanese were an enemy in retreat. In fact, they had made a clean break from Ioriabiawa and had established defences that were blocking Allen's advance on both routes to Templeton's Crossing. With supplies dropped at Myola, Allen could not easily support the advance being made along the Mount Bellamy track and, until the position forward of Templeton' Crossing was secured, there was the risk of Myola being compromised.
