The main attack went ahead, scheduled to start at 12:15 a.m. on 29 July but the Australian 7th Brigade was late in reaching its start line and its movement was detected by the German defenders; when the attack commenced, the Australians were met by a hail of machine gun fire. South of the road the 5th Brigade remained pinned down, unable to even get started. On their left, north of the road, the 7th Brigade encountered uncut wire. On the northern flank some minor progress was made by the 6th Brigade but everywhere else the attack was a failure. Including the attack and the preceding day of preparation the 2nd Division lost over 3,500 men; the 7th Brigade had to be withdrawn to reserve, so great were its losses.
