The final stage of the attack of the troops on the right was now made. They passed through the wide belts of enemy wire which fringed the plateau by way of wide gaps torn by our heavy artillery at fixed intervals. So they issued on the eastern slopes of Vimy Ridge--the first Allied troops to look down upon the level plain of Douai since the German occupation in 1914. They saw the villages of Farbus, Vimy, and Petit Vimy at their feet, and beyond these the hamlets of Willerval, Bailleul, Oppy, and Mericourt. They pressed on to Farbus Wood and Goulot Wood, and possessed themselves of several hostile batteries and much ammunition. By an early hour of the afternoon all the Canadian objectives save those of the left of the attack had been gained and the task of consolidating and strengthening these gains was well in hand. Throughout the day the most courageous and devoted cooperation was rendered to the Canadian corps by a brigade and a squadron of the Royal Flying Corps. The night saw all of Vimy Ridge, with the exception of a few trenches on Hill 145, secure in Canadian hands. During the next two days the Canadians, greatly hampered by dreadful weather, consolidated their new positions. When this had been accomplished, operations were again resumed. Attacks were delivered simultaneously at 5 A. M. on April 12, 1917, by English and Canadian troops against the two small hills known as "The Pimple," and the Bois-en-Hache, situated on either side of the Souchez River. Both of these positions were captured, with a number of prisoners and machine guns. Steps were at once taken to consolidate these gains and patrols were pushed forward to maintain touch with the enemy. The results of this last success at once declared themselves. Prior to its accomplishment there had been many signs that the enemy was preparing to make strong counterattacks from the direction of Givenchy and Hirondelle Woods to recover the Vimy Ridge. The positions captured on April 12, 1917, commanded both these localities, and he was therefore compelled to abandon the undertaking. His attitude in this neighborhood forthwith ceased to be aggressive, and indications of an immediate withdrawal from the areas commanded by the Vimy Ridge multiplied rapidly. The withdrawal commenced on the morning of April 13, 1917. Before noon on that day Canadian patrols had succeeded in occupying the southern portion of Givenchy-en-Gohelle, had pushed through Petit Vimy, and had reached the crossroads 500 yards northeast of the village. That afternoon English patrols north of the Souchez River crossed no-man's-land and entered Angres, while Canadian troops completed the occupation of Givenchy-en-Gohelle and the German trench system east of it. Farther south other troops seized Petit Vimy and Vimy, and Willerval and Bailleul were occupied in turn. For the next two weeks these gains were maintained without any further attempt to extend them.
