The Australians begin their attack against the Japanese defenders at Gona. The Diggers had suffered badly from the gruelling months of jungle warfare that each of the attacking units had endured. Each was about one third of its normal fighting strength.
The Diggers leading the advance run into Jap snipers about 1.5km south of Gona Mission, losing six killed in the initial clashes. They settle down to lay siege to the well-concealed Jap defences, forced the endure the pestilent swamp conditions.
