As always, when one saw these things, one longed for more eyes, better eyes, an abler pencil, to record them for our staff. An observer has great responsibilities at times: one cannot help remembering that a missed obstruction, a forgotten emplacement may mean a terrible toll of suffering. Our men would soon attack these trenches, relying largely on our photographs and information. . . . When, a week later, there rose above the battle the souls of all the brave men dead at Ctesiphon, seeing then with clearer eyes than mine, I pray they forgave our shortcomings and remembered we did our best. We could not circle over Ctesiphon, in spite of the interest we saw there, until our duty was performed, and had to fly on, leaving it to eastward. On the return journey, however, we promised ourselves as full an investigation as our petrol supply allowed, and had we returned with our report on what we had seen and done that day, things might have been very different. But what's the use of might-have-beens? After an hour's flying we sighted the telegraph line that was our objective, but when we approached it more closely a sad surprise awaited us, for instead of the blank surface which the map portrayed, we found that the line ran along a busy thoroughfare leading to Baghdad. Some ten thousand camels, it seemed to my disappointed eyes, were swaying and slouching towards the markets of the capital. We came low to observe the traffic better, and the camels craned their long necks upwards, burbling with surprise at this great new bird they had never seen. The ships of the desert, it seemed to me, disliked the ship of the air as much as we disapproved of them. Besides the camels, there were ammunition carts and armed soldiers along the road, making a landing impossible. Our demolition would only take three minutes under favourable conditions, but in three minutes even an Arab soldier can be trusted to hit an aeroplane and two airmen at point-blank range. So we flew westward down the road, looking for a landing ground. Baghdad was behind us now. On our right lay a great lake, and ahead we got an occasional glimpse of the Euphrates in the morning sun. At last--near a mound, which we afterwards heard was Nimrod's tomb--we saw that the telegraph line took a turn to northward, leaving the road by a mile or more. Here we decided to land. Nimrod's tomb was to be the tomb of our activities. While we were circling down I felt exactly as one feels at the start of a race, watching for the starting gate to rise. It was a tense but delightful moment.
