They did good work, and this Tank at Huns' Walk crawled along the hedge of wire and laid it flat, as its tracks there still show. Another Tank was slouching about under heavy shelling in search of strong posts, with the Australian boys close up to its flanks with their bayonets fixed. Suddenly, a burst of flame came from it, and it seemed a doomed thing. But out of the body of the beast came a very cool young man, who mounted high with bits of shell whistling by his head. He stamped out the fire, and did not hear the comments of the Australian lads, who said, "Gosh, that fellow is pretty game. He's all right." Much farther north another Tank came into action, with the Australians near. A few old remnants of charred wall and timber, where there was a strong post of Germans in concrete chambers, were causing our troops loss and worry. "Anything I can do to help you?" asked a Tank officer very politely through the steel trap-door. "Your machine-guns would be jolly useful in our trench," said an Australian officer. "We are a bit under strength here." The Tank officer was a friend in distress. He dismantled his machine-guns, took them into the trench and fought alongside the Australians until they were relieved. Just west of Van Hove Farm, in a gap between the Australians and the English, the Germans got into a place called Polka Estaminet--don't imagine it as a neat little inn with a penny-in-the-slot piano in the front parlour--and they had to be driven out by sharp rifle-fire. Next morning one of our men walked into a pocket of a hundred Germans, and a young Australian officer was told off with twenty men to bomb them out. There was a battle of bombs, which was very hot while it lasted, and then the Germans bolted off under machine-gun and rifle fire. Australian patrols went out and brought in forty wounded Germans and counted sixty to eighty dead. VII A BATTLE IN A THUNDER-STORM JUNE 29 In a violent thunder-storm whose noise and lightning mingled in an awesome way with the tumult and flame of the great artillery a minor battle broke out last evening round Lens and southwards beyond Oppy. The Canadians fought their way into Avion, a southern suburb of Lens, to a line giving them the larger half of the village, and driving the enemy back across the swamps to the outer defences of Lens city. Outside Oppy and south of it troops of old English county regiments seized the front-line system of German trenches and captured about 200 prisoners and several guns. West of Lens some Midland troops stormed and gained a line of trenches which belong to the main defences of the city, and north of it there was a big raid which caused great loss of life to the enemy. It was a heavy series of blows falling suddenly upon him, and giving him no time for a leisurely retirement to his inner line of defence in Lens.
