At last, weakened by their losses and with failing stores of ammunition, these two battalions were given the order to retire to a trench farther back, and the survivors of the most desperate action in Canadian history withdrew, still fighting, and established blocks in the communication-trenches down which the enemy was bombing, so that they could not pass those points to the line upon which here on the north of Lens the Canadians had fallen back. Southward there had been no withdrawal, and other battalions had forced their way forward a good distance, shutting up that entrance to the city and getting down into the deep tunnels, over which there howled the unceasing fire of the German heavies. Our own guns were hard at work, and I have already told how the Prussians were destroyed in the square of Lens by 12-inch shells and shrapnel. I could write more, but I have written enough. The Canadians never had fighting so hard as this, but the losses they have inflicted upon the enemy have made Lens a Prussian tomb, so that its tunnels are death vaults. The heart of the city is still a fortress, and the new garrison is still strong there, so that, like Thiepval, which held out for many weeks after it was enclosed on three sides, Lens will not fall in a night. But as a dwelling-place for German troops it is a city of abomination and dreadfulness. XIV THE AGONY OF ARMENTIÈRES SEPTEMBER 15 The harvests of France and Flanders have been gathered in, and already the plough, driven by men too old to fight or boys too small and young, or by peasant women whose men are somewhere near St.-Quentin or Verdun, is turning up the stubble in the fields and making a brown landscape where three weeks ago it was all gold and bronze.
