Early on 31 August, the 2/12th Infantry Battalion began moving towards KB Mission, with 'D' Company leading the way and struggling through muddy conditions along the track, which had been turned into a quagmire due to the heavy rain and equally heavy traffic.
After passing through the 61st Infantry Battalion's position, at around 9:00 am they began their counterattack along the north coast of Milne Bay.
As the Australians went they were harassed by snipers and ambush parties.
They also encountered several Japanese soldiers who tried to lure the Australians in close for attack by pretending to be dead.
In response, some Australians systematically bayoneted and shot the bodies of Japanese soldiers.
At noon, the 9th Infantry Battalion, a Militia unit from the 7th Infantry Brigade, dispatched two companies to occupy some of the ground that the 2/12th had regained around No.
3 Airstrip and the mission.

Making slow going amidst considerable resistance, the Australians nevertheless reached KB Mission late in the day.
A force of Japanese remained there, and the Australians attacked with bayonets fixed.
In the fighting that followed 60 Japanese were killed or wounded.
The Australians were then able to firmly establish themselves at the mission.
Meanwhile, the two companies from the 9th Battalion took up positions at Kilarbo and between the Gama River and Homo Creek with orders to establish blocking positions to allow the 2/12th to continue its advance the following morning.

That night, a force of around 300 Japanese who had been falling back since they had run into the 61st Infantry Battalion on Stephen's Ridge, encountered positions manned by the 2/12th and 9th Infantry Battalions around the Gama River.
In a surprise attack, the Australians inflicted heavy casualties on the Japanese.
After the battle the Australians estimated that up to 90 had been killed.
Following this the Japanese began to employ infiltration techniques in an attempt to pass through the numerous listening posts that had been set up along the side of the track which formed the front of one side of the 2/12th's position.
Elsewhere, at the mission, starting at around 8:00 pm, they carried out harassment operations in an effort to distract the Australians and assist their comrades to try to break through the Australian positions from the Gama River.
This lasted throughout the night.

The following morning, 1 September, the 2/12th Infantry Battalion went on the offensive again, while a force of seven Kittyhawks attacked the Japanese headquarters around Waga Waga.
By this time, the Japanese had abandoned the objective of reaching the airfields and instead sought only to hold off the Australians long enough to be evacuated.
This information was not known by the Allies, however, who were in fact expecting the Japanese to undertake further offensive action.
In this regard, the 2/9th, initially with orders to join the 2/12th's counterattack, was delayed an extra day after an erroneous intelligence report from MacArthur's headquarters warning Clowes of a renewed Japanese attack forced him to briefly adopt a more defensive posture.
The attack did not occur and, as a result, on 2 September the 2/9th was moved by barge up to the KB Mission.
The next day it took over from the 2/12th and led the Australian advance.
With the Japanese position at Milne Bay close to collapse, on 2 September Yano sent a radio message to the headquarters of the 8th Fleet which stated: "[w]e have reached the worst possible situation.
We will together calmly defend our position to the death.
We pray for absolute victory for the empire and for long-lasting fortune in battle for you all".

The terrain in this part of the bay offered significant advantage to defending forces, lined as it was with numerous creeks which slowed movement and obscured firing lanes.
Throughout 3 September, the 2/9th Infantry Battalion came up against significant resistance; in one engagement that took place around mid-morning along a stream to the west of Elevada Creek they lost 34 men killed or wounded as they attempted to f
