7 September 1942

At first light the Japanese main force attacks 2/27 Bn position on the forward slopes at Brigade Hill, bombarding them with mortar and mountain gunfire and trying to outflank them. For the first time in the campaign the Australians received brief air support when eight Boston bombers and four Kittyhawks bombed and strafed the Japanese position.

But the jungle protected the Japanese and they resumed their attacks immediately. The Australians fought back grimly as the enemy numbers began to take a heavy toll.

By evening all Australian positions are under heavy pressure as more than 2000 Japanese troops attack relentlessly.
