The Fourth Army attacks on 7, 12 and 18 October had captured little ground at great cost, against far less formidable defences than earlier in the battle. By the middle of the month, Haig and Rawlinson agreed that the army could not remain in its positions on such low ground through the winter but that the attacks of 23, 28 and 29 October were costly failures, in an even worse morass than earlier in the month. Fresh troops became exhausted just moving up to the front line and in most of the Fourth Army divisions battalion strengths had fallen from to knee deep in mud, eating cold food and soaking wet. Despite reports of the conditions and Cavan's objections, attacks in support of the Sixth Army continued. The British lost another for no gain of ground and the French also had meagre results, which led Foch to accept that little more could be achieved on the Fourth and Sixth army fronts.
