 The Allies formulated a plan to achieve this that would see the 9th Division conduct an amphibious landing east of Lae, while the 7th Division would move by air to Nadzab in the Markham Valley, which had been secured by parachute troops from the US 503rd Parachute Infantry Regiment and the 2/4th Field Regiment.From Nadzab, the 7th Division would advance on Lae from the south to support the 9th Division's drive towards Lae.At the same time, the Australian 3rd Division and the US 162nd Infantry Regiment would fight a diversionary action around Salamaua.
