Whenever you passed from east to west across the British zone during the war you would find somebody saying with fervour that somebody else, a little more to the west and a little higher in rank, had not even learnt his job well enough to keep out of the way. Subalterns, who by some odd arrangement of flukes had come through our attacks on the Somme in 1916 and in Artois and Flanders next year, would hoot at the notion--it had a vogue with part of the Staff in a tranquil far west--that the way to get on with the war was to raise a more specific thirst for blood in the private. Battalion commanders did not soon tire of telling how in the busiest days of big battles the unseen powers would pester them for instant returns of the number of shovels they had, or of the number of men who in civil life had been fitters, or had been moulders. Brigadiers would savagely wonder aloud whether it ever occurred to a higher command that to make little attack after little attack, each on a narrow, one-brigade front, was merely to ask to have each attack squashed flat in its turn by a fan-like convergence of fire from the enemy's guns on both flanks, not to speak of supports. The day the bad turn came for us, in the two-chaptered battle of Cambrai, an officer on the Staff of one of the worst-hit divisions observed: "Our attitude is just 'we told you so'." When the good turn in the war had come the next summer there was a day, not so good as the rest, when two squadrons of horse were sent to charge, in column, up a straight, treeless rising road for half a mile and take a little wood at the top. There were many machine-guns in the wood--how could there not have been?--and the whole air sang with warnings of that. No horse or man either got to the wood or came back. They were all in a few seconds lying in the white dust, almost in the order they rode in, the officer in command a little ahead of the rest. It looked, in its formal completeness, like a thing acted, a cinema play showing a part of Sennacherib's army on which the angel had breathed. On the road back from the place I met a corps commander--a great man at his work. When he heard his face crumpled up for a moment--he was a soft-hearted man. "Another of those damned cavalry follies!" he growled. His voice had the scorn that the man who is versed in to-day's practice feels for the men who still move among yesterday's theories. So it was, from east to west, all the way.
