It was a genial atmosphere in more ways than one. Always on coming in one's spectacles turned to ground-glass and one's out-door harness to melting lead. The heat came up an open stairway from the bowels of the earth, as did the chimney which I painfully mistook for a hand-rail the first night, when the Colonel was kind enough to take me down below. It was the first deep dug-out I had seen in working order, and it seemed to me deliciously safe and snug; the officers' berths in fascinating tiers, again as on shipboard, all but the Colonel's own, by itself at one end. It made me very jealous, yet rather proud, when I thought of our freezing lair upon the sunken road. Then, before we went, he took me up to an O.P. on top of all. I think we climbed up to it out of the _cul-de-sac_, and I know I cowered behind a chunk of parapet; but what I remember best is the zig-zag labyrinth in the foreground, that unending open grave with upturned earth complete, yet quiet as any that ever was filled in; and then the wide sweep of moonlit snow, enemy country nearly all, but at the moment still and peaceful as an arctic floe. Our own trenches the only solid signs of war, like the properties in front of a panorama; not a shot or a sound to give the rest more substance than a painted back-cloth. It was one of those dead pauses that occur on all but the noisiest nights, and make the whole war nowhere more unreal than on the battle-field. But when the very next day was at its quietest we had just the opposite experience. We were sitting at luncheon in this friendly mess, and the guns might have been a thousand miles away until they struck up all at once, like a musical-box in the middle of a tune. Their guns, this time; but you would not have thought it from the faces round the table. One or two exchanged glances; a lifted eyebrow was answered by a smile; but the conversation went on just the same until the officer nearest the door withdrew detachedly. New subject no longer avoidable, but treated with becoming levity. Not a bombardment, just a Strafe, we gathered; it might have been with blank shell, had we not heard them bursting. Exit another officer; enter man from below. Something like telegram in his hand: retaliation requested by front line. 'Put it through to Brigade.' Further retirements from board; less noise for moment. New sound: enemy 'plane over us, seeing what they've done. New row next door: our machine-guns on enemy 'plane! New note in distance: retaliation to esteemed order.... Other man and I alone at table, dying to go out and see fun, but obviously not our place. And then in a minute it is all over, not quite as quickly as it began, but getting on that way. Strafe stopped: 'plane buzzing away again: machine-guns giving it up as a bad job: cheery return of Belisarii, in the order of their going, Colonel last and cheeriest of all. 'Had my hair parted by a whizz-bang,' says he, 'up in that O.P. we were in last night.'
