The task of the two relieving divisions, the Fourth on the left and the Fifth on the right, was rather more difficult, as the Germans had begun to rally and the fog to lift. The Fourth Australians on the south bank of the Somme were especially troubled, as it soon became evident that the British attack on the north bank had been held up, with the result that the German guns on Chipilly Spur were all free to fire across from their high position upon the Australians in the plain to the south. Tank after tank and gun after gun were knocked out by direct hits, but the infantry was not to be stopped and continued to skirmish forward as best they might under so deadly a fire, finishing by the capture of Cerisy and of Morcourt. The Fifth Division on the right, with the 8th and 15th Brigades in front, made an equally fine advance, covering a good stretch of ground. Having considered the Canadians and the Australians, we turn now to the Third Corps on the north of the line. They were extended from Morlancourt to the north bank of the Somme, which is a broad canalised river over all this portion of its course. On the right was the Fifty-eighth London Division (Ramsay), with Lee's Eighteenth Division to the north of it, extending close to the Ancre, where Higginson's {32} Twelfth Division lay astride of that marshy stream. North of this again was the Forty-seventh Division (Gorringe), together with a brigade of the Thirty-third American Division. Two days before the great advance, on August 6, the Twenty-seventh Wurtemburg Division had made a sudden strong local attack astride of the Bray-Corbie Road, and had driven in the Eighteenth Divisional front, taking some hundreds of prisoners, though the British counter-attack regained most of the lost ground on the same and the following days. This unexpected episode somewhat deranged the details of the great attack, but the Eighteenth played its part manfully none the less, substituting the 36th Brigade of the Twelfth Division for the 54th Brigade, which had been considerably knocked about. None of the British prisoners taken seem to have given away the news of the coming advance, but it is probable that the sudden attack of the Wurtemburgers showed that it was suspected, and was intended to anticipate and to derange it.
