When we got over our battery I began to call them on the radio and they put out their panels. We picked out the target which we had agreed upon and sent the signal to fire. I had promised to adjust two batteries. The plan was to finish the adjustment of the first battery and then begin the second. So, after an hour and a half I completed the first adjustment after about fifteen salvos, which, I admit, was rather rotten work, then I started on the second. The name of my second target was “Travail Blanc” which consisted of a section of the trench which was especially heavily fortified with machine guns, having a sweep on our lines in the ravine beneath. I had just given them their first signal to fire, and of course, these batteries not having had a great deal of experience in adjusting artillery fire by airplane, were very, very slow in firing. Ordinarily the observer can time the firing, as a prompt battery fires immediately upon getting the signal from the airplane, and the observer can see the burst almost immediately thereafter. It is extremely important to get the first salvo bursts, for from this the observer knows approximately where to look for the next. So, having pressed the key, I was oblivious to all else in the world except the area immediately surrounding Travail Blanc. I must have eyed it for fully thirty seconds, which is an unusually long time to watch one particular spot on the earth, for with the speed of a modern German airplane against my antique A.R., in thirty seconds the Hun could get in a very advantageous place from out of a cloud or the sun. I was still straining my eyes on Travail Blanc when I heard the rat-a-tat-tat of something. It was the first time I had heard machine guns firing in the air while in the air myself, so I felt that we had probably lost altitude and that they were firing at us from the ground. I knew that I could not remedy the situation now, so I again turned my eyes toward Travail Blanc, when I saw the four bursts of the salvo strike about two hundred yards from the target. I had just started to reach for my key to send the correction to the battery when again I heard the long, continuous rata-tat-tat of a machine gun getting louder and louder. I leaned over the fuselage to take a look at the ground beneath me. I thought we should be high enough so that they could not possibly be firing at me and I could not figure what it was. I wondered where Schnurr and Thompson, my protectors, were, so I began to scan the air directly above me. As I threw my head backwards a streak of fire crossed my face barely missing me. I realized that “White Work” (Travail Blanc) was all wrong; my immediate target was “Dirty Work,” for instead of seeing my protecting plane above me there was bearing down upon us, with a speed that was indescribable, and spitting a thousand balls of deadly fire at me every minute, a German Albatros Scout Fighter, and directly behind it were two others of the same type. The Hun was already
