The battle which all the world has been expecting has begun. After weeks of intense bombardment, not on our side only, causing, as we know, grave alarm throughout Germany and anxiety in our enemy's command, we launched a great attack this morning on a front stretching, roughly, from the River Lys to Boesinghe. We have gained ground everywhere, and with the help of French troops, who are fighting shoulder to shoulder with our own men, in the northern part of the line above Boesinghe, we have captured the enemy's positions across the Yser Canal and thrust him back from a wide stretch of country between Pilkem and Hollebeke. He is fighting desperately at various points, with a great weight of artillery behind him, and has already made strong counter-attacks and flung up his reserves in order to check this sweeping advance. Many Tanks have gone forward with our infantry, sometimes in advance and sometimes behind, according to the plan of action mapped out for them, and have done better than well against several of the enemy's strong points, where, for a time, our men were held up by machine-gun fire. So far our losses are not heavy, and many of these are lightly wounded, but it is likely that the enemy's resistance will be stronger as the hours pass, because he realizes the greatness of our menace, and will, beyond doubt, bring up all the strength he has to save himself from a complete disaster. During the past few weeks the correspondents in the field have not even hinted at the approach of the battle that has opened to-day, though other people have not been so discreet, and the enemy himself has sounded the alarm. But we have seen many of the preparations for this terrific adventure in the north, and have counted the days when all these men we have seen passing along the roads, all these guns, and the tidal wave of ammunition which has flowed northwards should be ready for this new conflict, more formidable than any of the fighting which raged along the lines since April of this year. I am bound to say that as the days have drawn nearer some of us have shuddered at the frightful thing growing ripe for history as the harvests of France have ripened. Poring over maps of this northern front, and looking across the country from the coast-line and newly taken hills, like those of Wytschaete, the difficulty of the ground which our men have to attack has been horribly apparent. Those swamps in the north around Dixmude, the Yser Canal, which must be bridged under fire, the low flats of our lines around Ypres, like the well of an amphitheatre, with the enemy above on the Pilkem Ridge, were so full of peril for attacking troops that optimism itself might be frightened and downcast.
