The weather has changed again since yesterday, and there is no blue in the sky to-day and no sunshine, but cold rain-storms, cloaking all the line of battle in shrouds of mist. Fires are still burning in Lens, the grey smoke is drifting across the mine-fields, and every hour there are big explosions, showing that the German pioneers are still busy destroying all the wealth of machinery in the city and blowing up the roads before leaving. New prisoners describe all this frankly enough. Down one mine-shaft they flung 20,000 hand-grenades. They have enormous stores of explosives of every kind for this purpose, because this mining district was crammed with German stores. They had to leave Liévin in such haste that they could neither carry away this ammunition nor destroy all of it, and vast quantities of bombs, trench-mortars and shells have fallen into our hands.
Yesterday the English and Irish troops who had taken Bois-en-Hache with such fine courage, in spite of the most severe conditions of weather and ground, worked farther forward through Liévin. Explosions from concealed charges burst around them, and machine-gun fire from many redoubts swept down the long, straight streets of miners' cottages; but they worked their way up under cover, rushed several of the concrete emplacements, and took heroic risks with a most grim spirit. During the evening the enemy recovered from his first panic and sent supporting troops back into Lens to hold the line of trenches and machine-gun forts on the western side in order to delay our advance on to Lens until he has had more time to make ready his positions in the Drocourt-Quéant line, the Wotan end of the Hindenburg line, upon which we are forcing him to withdraw. It makes a difference to a number of poor souls expecting deliverance. According to prisoners there are about 2000 people, mostly women, old men, and children, living in the district of Lens, and waiting to break their way through to our side of the lines.
I set out to find them this morning, as there were reported rumours that they had escaped through Liévin. But this is untrue. Owing to the German rally they are still hemmed in by the enemy's machine-gun redoubts, and I am told that they are down in the cellars of a neighbouring village, taking cover from the shell-fire which we are pouring on the hostile strong points located in their cités.
