He rang off, but I knew by his expression that the matter was not yet settled. He got through to the --th Divisional Artillery and told the brigade-major that it was now 11.20 P.M., that no officer with a synchronised watch had arrived, and that the other brigade were now asking us to send an officer to them for orders for the coming battle. "I have no one who knows where they are," he went on. "They must know our location--we relieved one of their brigades. Why can't they send to us as arranged? I may have some one wandering about half the night trying to find them." In a little while the telephone bell tinkled again. "I'll answer them," said the colonel abruptly. "All right, I'll send to them," he replied stonily. "Where are we to find them, since they won't give us co-ordinates over the telephone?... A house with a red roof!... You can't tell us anything more definite?... Very well.... Good-bye." He put down the telephone with a little "Tchat!" that meant all forms of protest, annoyance, and sense of grievance. But now that no possible concession was to be gained, and certain precise work had to be done by us, he became the inexorable matter-of-fact executive leader again. "There's nothing for it," he said, looking at me. "You will have to go." Buildings with red roofs are not marked as such on military maps, and I bent glumly over the map board. However, houses were exceedingly few in this neighbourhood, and the chateau on the other side of the railway could be ruled out immediately. It was known as "The White Chateau," and I had noticed it in daytime. Besides, it had been so heavily shelled that our companion brigade had evacuated it two days before. "It's pretty certain to be somewhere in this area," observed the colonel, bending over me, and indicating a particular three thousand square yards on the map. "I expect that's the place--on the other side of the railway," and he pointed to a tiny oblong patch. I estimated that the house was three miles from where we were. It wanted but five minutes to midnight. I went outside, and flickering my electric torch stumbled across ruts and past occasional shell-holes to the copse, three hundred yards away, that sheltered the officers' chargers. I crackled a way among twigs and undergrowth until the piquet called out, "Who goes there?" "I think your groom's here, sir," he said, and the trees were so close set that my shoulder brushed the hindquarters of a row of mules as he piloted me along. "Are you there, Morgan?" he shouted, pulling open a waterproof ground-sheet that was fastened over a hole in the ground. "No--go away," called a voice angrily. "Where's Morgan sleep? Mr ---- wants him," persevered the piquet. We found my groom in another hole in the ground about thirty yards away. He listened sleepily while I told him to get my horses ready immediately. "Do you want feeds on, sir?" he asked, with visions apparently of an all-night ride.
