In the meantime, the Fourth Australian Division had been released by the fact that the remains of the Fifty-eighth Division and the 131st American Infantry Eegiment had, as will be told, cleared the Chipilly Ridge north of the river. Part of the Fourth Australians had crossed the river, fraternising greatly with the Americans, so that the officers on both sides had some trouble in sorting out their men--the more so as the comradeship had often taken the form of an exchange of hats and coats. On the night of August 10 the whole of the Fourth Australians had crossed to the north bank of the Somme near Sailly-le-Sec, and their commander, General Maclagan, had taken under him the Americans and also the 173rd and 174th Brigades of the British Fifty-eighth Division, much the worse for wear. [Sidenote: August 11.] The Third Australian Division had taken the place south of the Somme vacated by their {38} fellow-countrymen, and on the morning of August 11 they continued the attack in the direction of Proyart, that village being eventually carried by the 10th Brigade. It is needless to say that books might, and probably will, be written as to individual adventures and deeds of heroism, which in their aggregate supplied the driving force which carried the line ever more and more to the eastward. In giving a condensed account of the effects one can hardly get down to the more human story of the causes. Yet few greater deeds of valour can have been anywhere done than that of Sergeant Statton of the 40th Battalion, who in this engagement of Proyart seeing a neighbouring battalion, the 37th, held up by a nest of machine-guns, ran across to their aid, shot all the gunners at one gun, captured three guns single-handed, and chased the crews from two others. Many a battalion has spent itself in doing less. We shall now turn to the British Third Corps on the north of the Somme and so complete the account of the attack of the Fourth Army. It will be remembered that on the evening of August 8 they had made headway along the whole line but had been held up on the Chipilly Spur. [Sidenote: August 9.]
