The German infantry managed to advance for about near the Menin road on the southern flank and on the northern flank beyond the Reutelbeek, close to Black Watch Corner. The attack was supported by artillery-observation aircraft, ground-attack aircraft and a box-barrage fired behind the British front-line, which isolated the British defenders from reinforcements and cut off the supply of ammunition. Return-fire from the 33rd Division south of Polygon Wood and the 15th Australian Brigade of the 5th Australian Division along the southern edge of the wood forced the attackers under cover. German parties re-captured several pillboxes of the near Black Watch Corner, which had fallen to the British during the Battle of the Menin Road Ridge (20 September) but attempts to reinforce the attackers failed.
