April 2 and 3 were quiet days, but on the 4th there was a very violent and general attack along the line of the Nineteenth Corps, and of the Thirty-sixth French Corps (General Nollet) which lay to the immediate south. The main weight of the battle fell upon the Fourteenth Division in their new positions, and by nine o'clock in the morning the Germans had gained some success to the north of the main Amiens Road. The Australian 9th Brigade, which was south of the road, held their line, but had to fall back 500 yards in order to conform with the general position. At 11.30 the enemy was still making progress, mostly {153} on the front of the Fourteenth Division, and had reached the east edge of Hamel and of Bois de Vaire. The Third Cavalry Division, those indomitable troops, were thrown in to thicken the line of the Fourteenth, and the Canadian motor guns from Villers-Bretonneux were also brought into the battle. Later two battalions of the invaluable Australian infantry came up at the double from the 15th Australian Brigade. If ever the arrival of strong loyal men in a time of darkness brought joy and comfort with it, it was when the Australians relieved the British line in these later days of the second battle of the Somme. "God bless them!" was the silent prayer that went down the weary line. Ground had been lost south of Villers-Bretonneux, and the line was bent, but the whole of the Third and Fifth Australian Divisions were streaming down to their places in the defence. The end of the retreat was at hand. [Sidenote: Nineteenth Corps. April.] Upon the evening of April 4, the line which was to be permanent for many months to come began to define itself, and order gradually evolved out of ever-shifting chaos. Lee's Eighteenth Division was now in touch with the Thirty-sixth French Corps at Hangard. Then at the Bois l'Abbé lay the 9th Australian Brigade. North of this, at the Bois de Gentilles, was the Third Cavalry Division. Thence in succession came the 15th Australian Brigade, the 43rd Brigade, the remains of the Twenty-fourth Division, the 8th Australian Brigade, the other elements of the Fourteenth Division, the Fifth Australian Division near Aubigny, and the Fifty-eighth Division in the north. This summary will show how Australia had braced the line. Upon the next day, April 5, Butler's Third Corps took over {154} the whole area of the Nineteenth Corps, and the episode was at an end.
