of fancy timberings to hold up sliding trenches. In due course, when a few set battles, which sometimes gained several hundred yards, had wasted their many thousand lives, infallible forms of attack and defence developed themselves, were tried and generally found wanting, while scientific raids, the evolution of specialists, and the mass of regulated detail that more and more surrounded the life of the trenches, occupied their leisure between actions. Our battalions played themselves into the game at the awful price that must be paid for improvisation, however cheery; enduring with a philosophy that may have saved the war, the deviations and delays made necessary by the demands of the various political and other organisations at home.
In the same spirit they accepted the inevitable breakdowns in the business of war-by-experiment; for it is safe to say that there was hardly an operation in which platoons, companies, regiments, brigades, or divisions were not left with one or both flanks in the air. Among themselves, officers and men discussing such matters make it quite clear how and why such and such units broke, were misled, or delayed on their way into the line. But when a civilian presumes to assist, all ranks unite against his uninformed criticisms. He is warned that, once over the top, no plans hold, for the machine-*gun and the lie of the ground dictate the situation to the platoon-commander on whom all things depend and who sees, perhaps, fifty yards about him. There are limits, too, of shock and exhaustion beyond which humanity cannot be pressed without paying toll later. For which cause it may happen that a Division that has borne long agony unflinching, and sincerely believes itself capable of yet more, will, for no reason then apparent (at almost the mere rumour of noises in the night) collapse ignominiously on the same ground where, a month later, with two thirds of its strength casualties, it cuts coolly and cleanly to its goal. And its fellows, who have borne the same yoke, allow for this.
The compiler of these records, therefore, has made
