of Davidson's paper) agreed with one another that opportunities for further advance should be taken, and blamed the failures at Arras after 11 April, on renewed attacks without adequate artillery preparation. By Davidson's later account, at a conference on 28 June, Plumer also favoured permitting local commanders to attempt a deeper advance. Gough would later claim (in the 1940s) that he had wanted a shallower advance but had been overruled by Haig and Plumer – this appears to be at best a false recollection, if not a lie. Simpson wrote that Gough's wish to allow infantry to push forward was "more cautious than is usually supposed". Rawlinson was not involved in these discussions and his view that Gough wanted to go forward at the "Hurroosh" may well be more a comment on his knowledge of Gough's temperament than a strictly accurate description of Gough's plans by this stage. Eve of the offensive Haig briefed Gough (diary 28 June) that "the main advance" should be limited until the Gheluveld Plateau had been secured as far as Broodseinde. Haig was principally concerned that Gough was not giving sufficient weight to the attack on Gheluveld Plateau. Prior & Wilson write: "It is not evident that Gough allowed these views greatly to influence the disposition of his forces". The boundary of Fifth Army was extended south, placing another of Plumer's divisions under II Corps, so that Sanctuary Wood could be assaulted, lest the Germans there subject the attackers of the Gheluveld Plateau to enfilade fire. A XIV Corps memorandum states that they had sufficient high-explosive shell but insufficient heavy guns to bombard as thoroughly as they would have liked. Prior & Wilson point out that, had Gough followed Haig's advice to concentrate more weight against the Gheluveld Plateau, that would have reduced the effectiveness of the attack on his left and centre, but also argue that more heavy guns could have been obtained from Rawlinson's forces (threatening a diversionary attack along the Belgian Coast) and Plumer's Second Army (some of which was attacking the Gheluveld Plateau, but some of which was mounting largely fruitless diversionary attacks further south). Rawlinson urged the CIGS Robertson (29 June) of "the desirability of holding on to Goughy's coat tails and ordering him only to undertake the limited objective and not going beyond the range of his guns". He repeated this advice to Haig over dinner (3 July) although
