destroyed, but none actually fell into the German hands. Enough was done to show their possibilities, and also to prove that the Navy and the Flying Service had not sufficed to exhaust our amazing supply of high-spirited youths ready to undertake the most nerve-shaking tasks so long as a touch of sport gave them a flavour. The very names of these land cruisers, Crême de Menthe and the like, showed the joyous, debonair spirit in which their crews faced the unknown dangers of their new calling. Summing up the events of September 15, it was without any doubt the greatest British victory, though not the most important, which had been gained up to date in the War. July 1 was the most important, and all subsequent ones arose from it, since it was then that the Chinese Wall of Germany was breached. July 14 was also a considerable victory, but it was only a {262} portion of the line which was attacked, and that portion was partly regained for a time by the German counter-attacks. The battle of September 15, however, was on as huge a scale as that of July 1, but was devoid of those long stretches of untaken trench which made us pay so heavy a price for our victory. From the Pozières Ridge upon the left to Bouleaux Wood upon the right twelve divisions moved forward to victory, and, save in the small section of the Quadrilateral, everything gave way at once to that majestic advance. The ultimate objectives had been carefully defined, for the Battle of Loos had taught us that the infantry must not outrun the guns, but this pre-ordained limit was attained at almost every spot. Martinpuich, High Wood, Flers, Delville, and Leuze Wood, all passed permanently within the British lines, and the trophies of victory amounted to 5000 prisoners and a dozen guns. At this stage no less than 21,000 prisoners had been taken by the British and 34,000 by the French since the great series of battles was commenced upon July 1. {263} CHAPTER XI THE GAINING OF THE THIEPVAL RIDGE Assault on Thiepval by Eighteenth Division--Heavy fighting--Co-operation of Eleventh Division--Fall of Thiepval--Fall of Schwaben Redoubt--Taking of Stuff Redoubt--Important gains on the Ridge. Having treated the successful advance made by Rawlinson's Fourth Army upon September 15, it would be well before continuing the narrative of their further efforts to return to Gough's Army upon the north, the right Canadian wing of which had captured Courcelette, but which was occupied in the main with the advance upon the Thiepval Ridge.
