During the past fortnight we have been learning the difference between Warfare of Position and Warfare of Movement, and we are very, very tired. Moreover, the end of our labour is not yet. But we have made good. The Divisional General himself has informed us of the fact, in an official Order. So has the enemy, in an even more flattering fashion. He has fallen back—steadily and stubbornly—but back. The fighting began more than a fortnight ago. But first of all we had to get to the scene of action. That involved endless marches, through undulating, heavily wooded, exhausting country. It is the fall of the year. Rain is abundant, roads are not too numerous, and these are packed from end to end with traffic so close that it is sometimes impossible for a vehicle to find turning-space in ten miles. These roads, though well constructed and constantly reënforced, are none too good. They were never built to carry such traffic as this, and since the inevitable ditch on either side deprives them of lateral support, the effect of a constant stream of monstrously heavy vehicles upon the surface of one of them is that of a rolling-pin upon a strip of dough—it makes it wider. Not only wider, but thinner; for the edges of the road are squeezed out into the ditch, and the whole fabric loses cohesion. Almost anywhere, but in particular near the sides, a wheel is apt suddenly to find a soft spot and sink up to the axle, with consequent congestion and tumult. It is a double tide of traffic. Both streams are made up of similar constituents, with certain necessary contrasts. There are bodies of infantry, either going up into action or else coming out. There is no mistaking the latter. Their uniforms are splashed, their faces are caked, and their eyes are red for lack of sleep. They are obviously “all in,” but they hobble manfully along, with the comfortable satisfaction of men who have left behind them a task well and truly performed. They exchange ironic greetings with the full-fed, boisterous bands of adventurers whom they encounter hastening in the opposite direction.
