After I had been at my new post an hour, it then being near three o'clock in the morning, a motor car came swiftly toward me. I had been warned that I might expect staff officers to pass, and this, I thought, was undoubtedly some of them--otherwise the car would have advanced slowly. I stepped into the road and awaited its approach. As it neared me I saw that the two officers it contained wore the uniforms of the British staff. I could see the red tabs on their collars. There were two telegraph poles across the road near my post. Remembering this, I showed myself and called for the chauffeur to halt. He checked the car's speed but brought it ahead slowly. I shouted for the countersign. I was waiting for the occupants of the car to give it, intending to explain to them that they would have to stop until I called some one to help me remove the telegraph poles, when there was a sudden grinding of gears and the car shot ahead, full speed. I yelled a warning about the poles but the words left my lips at about the moment when the car bounced over them. Until that time I had no suspicion that the occupants of the car were not what they seemed. Even then, the manner in which they "rushed" my post seemed to me only due to some inexplicable misunderstanding. But I had marched, and fought, and gone sleepless and hungry until I was little more than a mechanical soldier. I was able to realize only that somebody, for some reason, had ignored my challenge and rushed a sentry post. I swung my rifle in the direction of the car, aimed accurately (in an automatic way), and pulled the trigger. The noise of an exploding tire followed the crack of my weapon. The car skidded, twisted for a moment, and then went on--faster than ever. My shot aroused our outpost. The alarm was given to the first of the connecting sentries and passed along quickly until it reached our company headquarters, on the roadside opposite to a chateau in which Brigade Staff headquarters had been established. Men half awake, tumbled into the roadway preparing to fire on something or somebody--they didn't know what. It was useless for the car to attempt to rush the crowd. Again the chauffeur checked it, this time bringing it to a full stop. One of the occupants (who, it will be remembered, were in staff uniform) demanded sharply of the sentry in front of the chateau: "What is the meaning of this? Are there nothing but blockheads about here? We have been fired on while looking for Brigade headquarters. Somebody should be court-martialled for this." The sentry saluted them and admitted them to the grounds of the chateau.
