2 January 1943

Buna falls as the final Japanese resistance is crushed and the position overrun, by the Americans from the west and the Australians from the east.

During the final hours of the fighting, the Japanese try to reinforce the Buna position by bringing a battalion by barge from Sanananda to the north. But seeing the position has already fallen, they withdraw.

Both sides suffer heavy losses at Buna but, for the Japanese, the result is disastrous. About 2700 Japanese troops with 11 pieces of artillery had held the position. Perhaps 400 of them escape to Sanananda. The rest perish at Buna.

The Allies had 2870 casualties, of whom 913 were Australian. Many more struck down by illness and tropical diseases.
