To make matters still more undramatic there was no battle going on at the precise moment when we shot downward out of the clouds, but only a rather languid artillery exchange. Even a regulating aeroplane which was sailing around directly below us and about half-way down between us and the earth, correcting the fire of some batteries, was having an exceptionally peaceful time of it. We could look down and see plainly the red, white and blue circles of France painted on the tops of its planes, but there were none of the customary woolly little white clouds of German shrapnel bursting round it during the few seconds that it remained in sight. Furthermore, the guns right below it and us were so cleverly concealed that they were quite invisible. The only signs of its being a front at all were the bursting shells from the French batteries. These little puffs of smoke in the hazy distance the pilot spotted unerringly, but he had a discouraging time pointing them out to my unaccustomed eyes as we raced along. So this, I fear, is all that any one visiting the front by aeroplane would have seen this afternoon. Possibly had we hung around longer we might have seen more, but the pilot and I both had important dinner engagements in Paris, and the sun was getting very low. We therefore reluctantly swept around and, leaving the silver band of the Aisne behind us, started for home. We kept low, not over 1,000 metres, so that the landscape was very clear and interesting. First we passed over the city of Compiègne, where I had lunched with Dr. Carrel only three days before to the accompaniment of an artillery obligato. Then right over the big, dark green Forest of Compiègne where I tried but failed to locate a château I had visited with Mme. Carrel. Then on and on over a further entrancing exhibit of parti-colored carpet fitting together at the edges as snugly as any completed picture-puzzle. Before long we reached Senlis, where I had stopped on my way to Compiègne the other day to take snap-shots of the streets of houses gutted by the Germans during their brief occupation before the battle of the Marne. Passing over Senlis, we dropped lower, so that I could get a clear bird's-eye view of the havoc. Then on and on, without incident, till the smoke of Paris came in sight, and on and on again, till I looked down through a thousand yards or so of space on the aviation field from which I had started just one hour and twenty-five minutes earlier.
