On 11 February, Tomforce, having moved to reinforce the Australians, launched a counter-attack on the captured village of Bukit Timah. The reconnaissance battalion was ordered to advance up the main road to the village, with 4RNR to their right and the 1/5SF (reinforced with elements of the 2/29th Australian Battalion, who had been temporarily attached to Tomforce) to their left. The reconnaissance battalion encountered strong Japanese resistance as they tried to enter the village near the railway station and could proceed no further. On their flank, the 1/5SF and the Australians advanced to within of the village, before being forced back. 4RNR took control of an area of high ground overlooking the village, but could advance no further due to a strong Japanese presence in the area. Meanwhile, Massy Force had assembled on the eastern side of MacRitchie Reservoir and was ordered to defend Bukit Tinggi, west of the reservoir, but Japanese forces arrived first. During the afternoon, Massy Force moved to the northern end of Bukit Timah Race Course and linked up with Tomforce who had pulled back following their failed attack on Bukit Timah. Late in the day, Massy Force absorbed Tomforce and the latter ceased to exist. It was later established that the Japanese 5th and 18th Divisions had occupied the area.
