 The arrival of this unit meant that the 2/17th, deadlocked around Jivevaneng, could be freed for the advance on Finschhafen, thus enabling the entire 20th Brigade to concentrate on that objective.After an attack across the Ilebbe Creek by the 2/13th Infantry Battalion, which cost the Australians 80 casualties on 1 October, the Japanese naval troops which were holding Finschhafen began to withdraw.On 2 October, the town fell to the Australians and the Japanese abandoned the Kakakog Ridge amidst heavy Australian air and artillery attacks.
