Lieutenant General Sir Richard Haking, whose British XI Corps would attack a strong part of the line with inexperienced 5th Division and British 61st (2nd South Midland) Division. The resulting Battle of Fromelles was an unmitigated disaster. In one night, the 5th Division sustained 5,533 casualties, while the 61st Division lost 1,547. Haking was principally responsible but McCay bore some of the blame. He made tactical errors; his order to vacate the first trench after it was cleared "undoubtedly contributed to the causes of failure". His refusal to permit a truce to recover wounded further damaged his popularity. For his part, McCay was mentioned in despatches a second time.
