 This did not change the situation around Sattelberg as by then the Australians had reached its southern slopes and the following day they began probing forward towards its summit.Throughout the day they launched a number of attacks, but heavy defensive fire pushed these back until a platoon under the command of Sergeant Tom Derrick fought its way almost to the top, with Derrick leading the way, destroying 10 Japanese positions with grenades as he went.With the Australians having secured a toehold just below the summit for the night, the Japanese withdrew under the cover of darkness and the following morning the advance to the mission was completed.
