It has been, one sees, a great enterprise; and the men who have worked so hard and unremittingly may well feel a legitimate pride in what they have so successfully accomplished. Yet in this, as in other spheres of activity, work can never stop. Bad weather and bombardment alike inflict constant havoc; and in spite of the most ingenious precautions the enemy always succeeds eventually in spotting the emplacement of this or that battery or in marking off an area which conceals a group of batteries. A furious fire from heavy guns is then concentrated upon the point discovered, and by the time our artillery manages to silence it the damage done is sometimes of such a nature that works which represent long months of labour may have to be practically reconstructed. CONCLUSION. We have now described the most outstanding features of the remarkable feat which the Belgian Army has accomplished with the object of rendering impregnable the important sector of the western front entrusted to its watchful care. It may claim to have safely defended the vital route leading to Dunkirk and Calais. Mere written words can, however, but imperfectly convey a complete idea of the colossal work it did among most discouraging and desolate surroundings; and prudence forbids us to say anything at all about many, and those by no means the least considerable, of the operations. Moreover, the few data which we have been permitted to give are but a slight indication of the efforts unsparingly made by men and officers alike. The task was done in self-effacing silence; the world at large scarcely knows of it. But perhaps in these few pages we may have succeeded in making the merit of our fearless and tenacious troops better appreciated, and in showing how well they have earned the homage due to the determined energy which they have displayed for more than three years, with no thought but that of valiantly performing a duty of prime importance to the common cause, though it brings no glory with it.
