"We move off at a quarter to four," he said, "up Fountain Alley and Scottish Trench, into Central Boyau"--"boyau" is the name which is given to a communication-trench in trenches which, like those in front of us, are of French extraction--"and so over the parapet. There we extend, as arranged, into lines of half-companies, and go at 'em, making Douvrin our objective, and keeping the Hohenzollern and Fosse Eight upon our left." Fosse Eight is a mighty waste-heap, such as you may behold anywhere along the railway in the colliery districts between Glasgow and Edinburgh. The official map calls such an eminence a Fosse; the Royal Engineers call it a Dump; Operation Orders call it a Slag-Heap; experts like Ogg and Hogg (who ought to know if any one does) call it a Bing. From this distance, two miles away, the Fosse looks as big as North Berwick Law. It is one of the many scattered about this district, all carefully numbered by the Ordnance. There are others, again, towards Hulluch and Loos. Number Eight has been the object of pressing attentions on the part of our big guns ever since the bombardment began, three weeks ago; but it still stands up--gaunt, grim, and defiant--against the eastern sky. Whether any one is left alive upon it, or in it, is another question. We shall have cause to remember Fosse Eight before this fight is over. The Hohenzollern Redoubt, on the other hand, is a most inconspicuous object, but a very important factor in the present situation. It has been thrust forward from the Bosche lines to within a hundred yards of our own--a great promontory, a maze of trenches, machine-gun emplacements, and barbed wire, all flush with or under the ground, and terribly difficult to cripple by shell fire. It has been a source of great exasperation to us--a starting-point for saps, mines, and bombing parties. As already stated, this mighty fortress has been christened by its constructors, the Hohenzollern. It is attached to its parent trench-line by two communicating trenches, which the British Army, not to be outdone in reverence to the most august of dynasties, have named Big and Little Willie respectively. A struggling dawn breaks, bringing with it promise of rain, and the regiment begins to marshal in the trench called Fountain Alley, along which it is to wind, snake-like, in the wake of the preceding troops, until it debouches over the parapet, a full mile away, and extends into line. Presently the order is given to move off, and the snake begins to writhe. Progress is steady, but not exhilarating. We have several battalions of the Division in front of us (which Bobby Little resents as a personal affront), but have been assured that we shall see all the fighting we want. The situation appears to be that owing to the terrific artillery bombardment the attacking force will meet with little or no opposition in the German front-line trenches; or second line, for that matter.
