On the morning of 15 January, Japanese aircraft arrived and began dive-bombing the town of Gemas. Six hours after the ambush the Japanese had repaired the bridge and were moving on their way towards Galleghan's main position at the peg on the Gemas-Tampin road. The surviving members of Mukaide Force were now reinforced by the Japanese 11th Regiment. The 2/30th Battalion were positioned astride the road and railway line with two 2-Pounder Anti-Tank Guns facing the road. By 10:00 on 15 January, Japanese infantry clashed with the Allied defence lines, and as the day wore on they were supported by an increasing number of tanks. In a short but violent battle the Australian anti-tank guns, from the 2/4th Australian Anti-Tank Regiment, destroyed six of eight Japanese tanks and their supporting infantry inflicted heavy casualties on the Japanese infantry following the tanks.
