Japanese at Buna are now cornered in a small area around their headquarters at Buna Government Station with their backs to the sea.
The Australians and the Americans attack from the east and the south. In Rabaul, Gen Adachi, whose only son is one of the Buna defenders, orders his navy to try to get supplies through to the doomed defenders at Buna by submarine. The attempt fails. Adachi’s son dies.
