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. 2 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.
