The Japanese defenders at Buna are locked in a tight area around the old Buna Government Station, with the Americans crushing them from the west and the Australians from the east.
All the while the Australians are suffering casualties as the Japanese try to take as many with them as they can as they fight to their last breath.
During the day the Allies break in on both sides and overrun the last Japanese positions. The Jap HQ there is ordered to retreat to Giruwa River.
On New Year’s Eve, the Australians of 2/12th Battalion are poised to make a final thrust into the heavily-fortified Japanese defences at Giropa Plantation.
