Wilder-Neligan returned to duty on 7 July. On 22–23 July, the 10th Battalion was back in the line opposite Merris. Characteristically, on his own initiative, Wilder-Neligan pushed strong patrols forward on his flanks in an effort to envelop the village. He had achieved some success, and believed that the capture of the village was imminent when a heavy German barrage descended on the battalion outpost line. The new divisional commander, Major General William Glasgow, now became aware of Wilder-Neligan's operation, and, as Wilder-Neligan could not guarantee communication with his flanking patrols due to the barrage, Glasgow ordered the 10th Battalion to withdraw. In his report on the operation, Wilder-Neligan noted that between 60 and 70 Germans had been killed and four prisoners taken, for the loss of two killed and seven wounded. Regarding this operation, he reported that, "the ultimate withdrawal in obedience to the order of the Divisional Commander in no way mitigated its success".
