After the Malayan campaign, the 27th Brigade initially took part in the defence of Singapore by defending the Causeway area. The Japanese assault began on the night of 8/9 February, and fell largely on the 22nd Brigade's sector, where two Japanese divisions landed during the Battle of Sarimbun Beach. The brigade's troops managed to hold their area, fending off some flanking efforts by the Japanese along the Kranji River, and the &lt;a href="2/29th%20Battalion%20%28Australia%29"&gt;2/29th Battalion&lt;/a&gt; was sent south to help bolster the 22nd Brigade. The following night, another Japanese landing fell in the 27th Brigade's area, and heavy fighting took place during the Battle of Kranji. The Japanese suffered heavy casualties from the defenders' machine guns and mortars, as well as burning oil that had been sluiced across the water. The attacking troops managed to establish a beachhead and the 27th Brigade's headquarters was subsequently cut off from its battalions, as the Allies were pushed back towards the centre of the island. As the Allied perimeter continued to shrink around the town, the 8th Division units were brought together around Tanglin Barracks, where they remained until the garrison surrendered on 15 February.
