But however much the Tanks may disconcert the gallant Colonel Newcomes who throw an air of restraint over our victorious front, there can be no doubt that they are an important as well as a novel development of the modern offensive. Of course neither the Tanks nor their very obvious next developments going to wrest the decisive pre-eminence from the aeroplane. The aeroplane remains now more than ever the instrument of victory upon the western front. Aerial ascendancy, properly utilised, is victory. But the mobile armoured big gun and the Tank as a machine-gun silencer must enormously facilitate an advance against the blinded enemy. Neither of them can advance against properly aimed big gun fire. That has to be disposed of before they make their entrance. It remains the function of the aeroplane to locate the hostile big guns and to direct the tir de demolition upon them before the advance begins—possibly even to bomb them out. But hitherto, after the destruction of driving back of the defender's big guns has been effected, the dug-out and the machine gun have still inflicted heavy losses upon the advancing infantry until the fight is won. So soon as the big guns are out, the tanks will advance, destroying machine guns, completing the destruction of the wire, and holding prisoners immobile. Then the infantry will follow to gather in the sheaves. Multitudinously produced and—I write it with a defiant eye on Colonel Newcome—properly handled, these land ironclads are going to do very great things in shortening the war, in pursuit, in breaking up the retreating enemy. Given the air ascendancy, and I am utterly unable to imagine any way of conclusively stopping or even greatly delaying an offensive thus equipped.

The young of even the most horrible beasts have something piquant and engaging about them, and so I suppose it is in the way of things that the land ironclad which opens a new and more dreadful and destructive phase in the human folly of warfare, should appear first as if it were a joke. Never has any such thing so completely masked its wickedness under an appearance of genial silliness. The Tank is a creature to which one naturally flings a pet name; the five or six I was shown wandering, rooting and climbing over obstacles, round a large field near X, were as amusing and disarming as a little of lively young pigs.

At first the War Office prevented the publication of any pictures or descriptions of these contrivances except abroad; then abruptly the embargo was relaxed, and the press was flooded with photographs. The reader will be familiar now with their appearance. They resemble large slugs with an underside a little like the flattened rockers of a rocking-horse, slugs between 20 and 40 feet long. They are like flat-sided slugs, slugs of spirit, who raise an enquiring snout, like the snout of a dogfish, into the air. They crawl upon their bellies in a way that would be tedious to describe to the general reader and unnecessary to describe to the enquiring specialists. They go over the ground with the sliding speed of active snails. Behind them trail two wheels, supporting a flimsy tail, wheels that strike one as incongruous as if a monster began kangaroo and ended doll's perambulator. (These wheels annoy me.) They are not steely monsters; they are painted with drab and unassuming colours that are fashionable in modern warfare, so that the armour seems rather like the integument of a rhinoceros. At the sides of the head project armoured checks, and from above these stick out guns that look like stalked eyes. That is the general appearance of the contemporary tank.

It slides on the ground; the silly little wheels that so detract from the genial bestiality of its appearance dandle and bump behind it. It swings about its axis. It comes to an obstacle, a low wall let us say, or a heap of bricks, and sets to work to climb it with its snout. It rears over the obstacle, it raises its straining belly, it overhangs more and more, and at last topples forward; it sways upon the heap and then goes plunging downwards, sticking out the weak counterpoise of its wheeled tail. If it comes to a house or a tree or a wall or such-like obstruction it rams against it so as to bring all its weight to bear upon it—it weighs some tons—and then climbs over the debris. I saw it, and incredulous soldiers of experience watched it at the same time, cross trenches and wallow amazingly through muddy exaggerations of small holes. Then I repeated the tour inside.

Again the Tank is like a slug. The slug, as every biological student knows, is unexpectedly complicated inside. The Tank is as crowded with inward parts as a battleship. It is filled with engines, guns and ammunition, and in the interstices men.

“You will smash your hat,” said Colonel Stern. “No; keep it on, or else you will smash your head.”

Only Mr. C. R. W. Nevinson could do justice to the interior of a Tank. You see a hand gripping something; you see the eyes and forehead of an engineer's face; you perceive that an overall bluishness beyond the engine is the back of another man. “Don't hold that,” says someone; “it is too hot. Hold on to that.” The engines roar, so loudly that I doubt whether one could hear guns without; the floor begins to slope and slopes until one seems to be at forty-five degrees or thereabouts; then the whole concern swings up and sways and slants the other way. You have crossed a bank. You heel sideways. Through the door which has been left open you see the little group of engineers, staff officers and naval men receding and falling away behind you. You straighten up and go up hill. You halt and begin to rotate. Through the open door, the green field, with its red walls, rows of worksheds and forests of chimneys in the background, begins a steady processional movement. The group of engineers and officers and naval men appears at the other side of the door and farther off. Then comes a sprint down hill. You descend and stretch your legs.

About the field other Tanks are doing their stunts. One is struggling in an apoplectic way in the mud pit with a cheek half buried. It noses its way out and on with an air of animal relief.

They are like jokes by Heath Robinson. One forgets that these things have already saved the lives of many hundreds of our soldiers and smashed and defeated thousands of Germans.
