The main German attack upon the extreme south of the corps line on March 27 fell upon the Thirty-sixth Division in the direction of Erches, with the result that the Ulster men fell slowly back upon Arvillers, the 60th Brigade throwing back a defensive flank to correspond. By 12.30 Bouchoir, held by the 90th Brigade, was gained by the Germans, but the British formed a new line to the immediate westward of the village. An attack upon Folies was thrown back by the 59th Brigade. Towards evening some order came out of a rather tangled position, which may well be obscure both to writer and reader, since soldiers upon the spot found the greatest difficulty in separating the various confused elements. As night fell upon March 27 after much desultory and inconclusive local fighting, there was no great change in the British line which ran from Warvillers, still held by the Twenty-fourth Division, to the west of Bouchoir, where the Thirtieth held the line, and down to Arvillers held by the 60th Brigade of the Twentieth Division, which was temporarily out of touch with the Thirty-sixth Division. Hangest was held by the Sixty-first Division, and Le Quesnel by the Sixty-first and the French. That night the Twentieth Division was ordered to join the Nineteenth {174} Corps, and their record under this new command will be found in the preceding chapter. One would have thought that they had reached the limits of human endurance, and their total numbers were not more than a thousand, and yet they were but at the beginning of a new chapter in their glorious history. The same words apply to their comrades of the Sixty-first Division, who were also ordered north. They were relieved by the French at Arvillers, and this portion of the line was on March 28 pressed back to the west of Hangest. [Sidenote: March 28.]
