Delving into this new game I indulged in certain psychological conclusions which took my mind off of the thing that had been troubling me; namely, the unpeaceful condition of my mind. This was most interesting. They had fired about six or seven salvos and were coming very near to the target, which was a cross-road. I thought it must be a wonderful observer to guide the battery with such unfailing accuracy and I looked forward to the time when I too might be a genuine sky spy and with American batteries seek out the enemy and destroy him, for after all was not the position of the aerial observer one of the most dangerous of the army, the spy—for his greatest mission was to find out the intentions of the enemy and if he succeeded in bringing back the information without being seen all would be well, and if he was seen it meant he had to fight for his life. Like the spy he, too, lived within the lines of the enemy.
This was the gist of my thoughts when I suddenly looked down at the panels and saw a huge “Y” displayed. I did not pay much attention to the “Y” but I saw Jones’ plane taking a steep spiral toward the earth. I did not call the attention of my pilot to it because I thought “Y” was something usual, meaning, perhaps, that the signals were not understood so Jones was going down low to get closer to the battery in order that his wireless could be heard, but Jones kept going right on down near the battery and finally kept circling around close by at about three hundred feet altitude. I looked around and did not pay any great heed; I thought Jones would soon climb up again. In a few moments I saw the battery take in their “Y” and put it out again; take it in and put it out, as if to attract my attention. Then I saw them running back and forth with individual panels in different directions, which had a sort of cinema effect. Then they brought out double panels and made a great, huge “Y.” Then I thought “Y” must mean something if they were making all that fuss about it, so I thought “Y”—“Y”—“Y”—“Y.” It was a memory test for me. I felt I should remember some of those panels and here was the chance to think clear and quick. I went through the various fake memory courses I had taken and tried in every way to determine the meaning of “Y,” so after trying to figure it out by the law of association, the law of likeness of sound, the law of impress and five other such hopeless laws I began to regret that I had paid so much for that memory course. Then I casually took out my map chart to find out what “Y” meant. As I ran slowly down the list of signals I came to “Y” and looking across it I saw “Attention! Ennemi avion pres de vous,” which in English means “Look out! Enemy plane close to you.” I thought I did not know French but I certainly acquired it with the speed of lightning. I dropped my map board like a shot, jumped up in my cockpit, grabbed my machine guns, released the tourelle, and whether I knew anything about that tourelle or not, it followed me as I spun around three times in a complete circle of three hundred and sixty degrees with the speed of a ballet dancer—I was bent on getting anything near me. I stopped—looked frantically at the pilot, expecting to find him dead. He had turned around to find out what the rumpus was about. I did nothing but to give him a sickly smile for I had nothing else to give. They had a signal commonly used among observers to describe a cross with the forefinger and point when the observer saw a German plane, but this was among the thousand things I had not learned about aerial observation. So, he went on, straight flying, just aimlessly drifting on.
