be limited to the German first line. The plan was thus well known, even to "the Mademoiselles" behind the British lines, although in practice the Germans, holding the high ground, could see enough of the British lines to guess that an attack was coming. In the event the attack was postponed because of rain (which made it hard for artillery to register targets). Haking opened his advanced corps HQ at Sailly at 6am on 17 July – a sign that he did not expect the attack to be postponed for long, let alone cancelled. At 8.30am he sent a despatch in which, contradicting the assurances he had given, he admitted that many of the Australian gunners had never fired on the Western Front before, and that many of the infantry were "not fully trained" and "do not appear to be very anxious for the attack to be delivered". Eventually the start times (11am for artillery, 6pm for the infantry attack) were fixed for 19 July. Although only the German front line was the target, plans were being discussed for further advances, possibly by night, in the event of complete success being achieved. Initial attack A "surprise" attack was launched after an 11-hour bombardment, at 6pm on 19 July. Haking launched an attack by two divisions (61st British Division – which consisted of 182nd, 183rd and 184th Brigades under the command of Major-General Colin Mackenzie – and 5th Australian Division) which cost 7,000 casualties. 18th and 14th Australian brigades managed to cross No Mans Land, but then suffered greater casualties in the retreat than in the original attack. 15th and 184th Australian brigades suffered severe casualties crossing No Mans Land for no result. Controversy over plans to renew the attack A further attack at 9pm was cancelled by 61st Division, but one Australian battalion attacked alone and suffered severe casualties. This earned the undying disgust of the commander of the Australian 15th Brigade, Brigadier-General Harold 'Pompey' Elliott, who had seen 80% of his two assaulting battalions killed, wounded or captured by night-fall. The truth appears to be slightly more complicated. Haking, in possession of incomplete information, initially ordered a renewal of the attack the next day. Having received fresh information about the three brigades of 61st Div. at 8.20pm he ordered the 9pm attack to be abandoned and that 183 and 184 brigades return to or remain in their own front
