criminal methods by which the war had been waged forbade every thought of an incomplete settlement. With stern and deliberate determination the French and British turned to their task, strengthened by the knowledge that the vanguard of America was already in the field, weak as yet in numbers, but the head of that long column which extended across the Atlantic and was based upon the virile nation of a hundred million souls beyond. {24} CHAPTER II ATTACK OF RAWLINSON's FOURTH ARMY The Battle of Amiens, August 8-22 Great British victory--Advance of the Canadians--Of the Australians--Of the Third Corps--Hard struggle at Chipilly--American assistance--Continuance of the operations--Great importance of the battle. [Sidenote: August 8.] In the tremendous and decisive operations which we are now about to examine, it is very necessary to have some fixed scheme in the method of description lest the reader be inextricably lost in the long line of advancing corps and armies. A chapter will be devoted, therefore, to the attack made by Rawlinson's Fourth Army whilst it was operating alone from August 8 to August 22. At that date Byng's Third Army joined in the fray, and subsequently, on August 28, Horne's First Army came into action. For the present, however, we can devote ourselves whole-heartedly to the record of Rawlinson's Army, all the rest being inactive. When the others come in, that is, after August 22, a definite system of narrative will be adopted. [Illustration: Advance of Fourth Army, August 8, showing Gains up to August 12, and Final Position after the Fall of Peronne] Before describing the great battle some reference should be made to the action of Le Hamel fought on July 4, noticeable as having been the first Allied offensive since the early spring. Its complete success, {25} after the long series of troubles which had plunged all friends of freedom into gloom, made it more important than the numbers engaged or the gain of ground would indicate. It was carried out by the Australian Corps, acting as part of the Fourth Army, and is noticeable because a unit from the Thirty-third American Division took part in the operations. Le Hamel was taken and the Vaire Wood to the immediate south of the Somme. The gain of ground was about a mile in depth on a front of several miles, and the advance was so swift that a considerable number of prisoners, 1500 in all, were taken, many of them still encumbered by their gas-masks. Some sixty tanks took part in the advance, and did splendid work in rolling out the machine-gun nests of the Germans. Sir John Monash has attributed some of the splendid efficiency of the Australian arrangements and their cunning in the mutual support of guns, tanks, and infantry, so often to be shown in the next four months, to the experience gained in this small battle.
