"Zero is at four; come at two," Howell said when I was going.

At two the next afternoon I found him occupied less with final details than with the routine business of one who is clearing his desk preparatory to a week-end holiday. Against the wall of what had been once a bedroom in the house of the leading citizen of the town, which was his office, he had an improvised bookkeeper's desk and on it were the mapped plans of the afternoon's operation, which he had worked over with the diligence and professional earnestness of an architect over his blue prints. He had been over the ground and studied it with the care of a landscape gardener who is going to make improvements.

"A smoke barrage screen along there," he explained, indicating the line of a German trench, "but a real attack along here"—which sounded familiar from staff officers in chateaux.

Every detail of the German positions was accurately outlined, yard by yard, their machine guns definitely located.

"We're uncertain about that one," he remarked, laying his pencil on the map symbol for an M.G.

Trench mortars had another symbol, deep dugouts another. It was the business of somebody to get all this information without being communicative about his methods. Referring to a section of a hundred yards or more he remarked that an eager company commander had thought that he could take a bit of German trench there and had taken it, which meant that the gunners had to be informed so as to rearrange the barrage or curtain of fire with the resulting necessity of fresh observations and fresh registry of practice shots. I judged that Howell did not want the men to be too eager; he wanted them just eager enough.

This game being played along the whole front has, of course, been likened to chess, with guns and men as pieces. I had in mind the dummy actors and dummy scenery with which stage managers try out their acts, only in this instance there was never any rehearsal on the actual stage with the actual scenery unless a first attack had failed, as the Germans will not permit such liberties except under machine gun fire. A call or two came over the telephone about some minor details, the principal ones being already settled.

"It's time to go," he said finally.

The corps commander was downstairs in the dining-room comfortably smoking his pipe after tea. There would be nothing for him to do until news of the attack had been received. "I hope you will see a good show," he remarked, by way of au revoir.

How earnestly he hoped it there is no use of mentioning here. It is taken for granted. Carefully thought out plans backed by hundreds of guns and the lives of men at stake—and against the Thiepval fortifications!
