20 July 1942

Transport ship Gili Gili reaches Buna and immediately begins unloading supplies for carriers to take to B Coy, now at Kokoda.

They don’t know it but the carriers leave with the much-needed supplies less that 24 hours ahead of the advance party of the Japanese invasion force headed for the same coastal village.

3 transport ships carrying Japanese 5th Sasebo Special Naval Landing Forces and Yokoyama Detachment (17th Army) depart Rabaul, headed for the North coast of Papua. 40 Japanese aircraft raid Port Moresby on the South coast.
