Since my return I have been able to see the Tank at home, through the courtesy of the Ministry of Munitions. They have progressed far beyond any recognisable resemblance to the initiatives of Mr. Diplock; they have approximated rather to the American caterpillar. As I suspected when first I heard of these devices, the War Office and the old army people had practically nothing to do with their development. They took to it very reluctantly--as they have taken to every novelty in this war. One brilliant general scrawled over an early proposal the entirely characteristic comment that it was a pity the inventor could not use his imagination to better purpose. (That foolish British trick of sneering at “imagination” has cost us hundreds of thousands of useless casualties and may yet lose us the war.) Tanks were first mooted at the front about a year and a half ago; Mr. Winston Churchill was then asking questions about their practicability; he filled many simple souls with terror; they thought him a most dangerous lunatic. The actual making of the Tanks arose as an irregular side development of the armoured-car branch of the Royal Naval Air Service work. The names most closely associated with the work are (I quote a reply of Dr. Macnamara's in the House of Commons) Mr. d'Eyncourt, the Director of Naval Construction, Mr. W. O. Tritton, Lieut. Wilson, R.N.A.S., Mr. Bussell, Lieut. Stern, R.N.A.S., who is now Colonel Stern, Captain Symes, and Mr. F. Skeens. There are many other claims too numerous to mention in detail.
