On August 10 the Third Corps front was pushed forward in the morning by a system of infiltration, British and American patrols scouting and fighting through the eastern portion of Cressaire Wood. Before evening, without any serious fighting, they reached the old French Amiens defence line, which was the original full objective upon this front. Having entirely accomplished his arduous task General Butler, who had been handicapped by an illness which he disregarded while his work called for his presence, took a short spell of rest, his place being taken by General Godley. The Forty-seventh Division (Gorringe) came across to the right wing, relieving the Eighteenth Division, while shortly after the Thirty-third American Division, to the great regret of their British comrades, entrained for the south to join the main American army, but not before their 133rd Eegiment, acting with the 13th Australian Brigade, had taken Etinehem Spur, to the north of the River Somme. The action now died down in this quarter. In the three days of fighting General Butler's Corps had taken 90 guns and 3000 prisoners, while, in the words of General Rawlinson, "in protecting the left flank of the Fourth Army they were given a difficult task which was carried out with a determination and gallantry beyond all praise." The losses had been 6500, 500 of which were from the American Regiment. The general result of the battle {41} by the night of August 11 was that the French had taken 8000 and the British 21,000 prisoners with 400 guns, so that it was already clear that the greatest victory which the British Army had yet won was that which initiated the final advance. In spite of all this success it is to be borne in mind, however, that the Allies had only reached the old German front line trenches of 1916, which were now a valuable barrier for the rear of the retreating army. There was a pause now while the Fourth Army was waiting for their comrades of the Third Army on the left to develop their extension of the attack. Meanwhile many small actions and local advances on Rawlinson's front kept his opponents from having time to reorganise. On August 13, as already mentioned, Americans and Australians advanced the line to the north of the river along the strip which is bounded upon the left by the Bray-Corbie Road. On August 14 the Canadian 7th Brigade took Parvillers after some very stiff local fighting. They were driven out again that night by the heavy concentration of the German artillery, but next morning, with the co-operation upon their flank of their comrades of the 9th Brigade, they won it once more. In this operation the 52nd Battalion took Damery, while the French carried the wood to the south of the village. There was a strong counter-attack in the afternoon by the German One hundred and twenty-first Division, but it was beaten back, leaving a number of prisoners. About August 20 the Canadians began to slip quietly out
