Archie now seemed to treat the deliberation of the solitary machine's movements as a challenge to his ability, and he determined to make us pay for our seeming contempt. An ugly barrage of A.-A. shell-bursts separated us from friendly air, the discs of black smoke expanding as they hung in little clusters. Into this barrier of hate we went unwillingly, like children sent to church as a duty.
Scores of staccato war-whoops reminded us that the Boche gunners wanted our scalp. I don't know how V. felt about it, but I well know that I was in a state of acute fear. Half-way to Pozières I abandoned checking the ground by the map, and judged the final photographs by counting the seconds between each—"one, two, three, four (wouff! wouff! wouff! wouff!)"; pull the string, press forward the loading-handle, bring it back; "one, two, three, four (wouff! wouff! wouff! wouff!)," et-cetera. Just as the final plate-number showed on the indicator a mighty report from underneath startled us, and the machine was pressed upward, left wing down.
This was terrifying enough but not harmful, for not one of the fragments from the near burst touched us, strange to say. The pilot righted the bus, and I made the last exposure, without, I am afraid, caring what patch of earth was shuttered on to the plate.
Nose down and engine full out, we hared over the trenches. Archie's hate followed for some distance, but to no purpose; and at last we were at liberty to fly home, at peace with the wind and the world. We landed less than three-quarters of an hour after we had left the aerodrome in a hurry.
"Good boys," said the Squadron Commander; "now see that lightning is used in developing your prints."
The camera was rushed to the photographic lorry, the plates were unloaded in the dark hut, the negatives were developed. Half an hour later I received the first proofs, and, with them, some degree of disappointment. Those covering the first outward and return journey between Pozières and Le Sars were good, as were the next three, at the beginning of the second journey. Then came a confused blur of superimposed ground-patterns, and at the last five results blank as the brain of a flapper. A jamb in the upper changing-box had led to five exposures on the one plate.
As you know, mon amie, I am a fool. But I do not like to be reminded of the self-evident fact. The photographic officer said I must have made some silly mistake with the loading handle, and he remarked sadly that the camera was supposed to be foolproof. I said he must have made some silly mistake when inspecting the camera before it left his workshop, and I remarked viciously that the camera was foolproof against a careless operator, but by no means foolproof against the careless expert. There we left the subject and the spoiled plates, as the evening was too far advanced for the trip to be repeated. As the photoman has a pleasant job at wing headquarters, whereas I am but an observer—that is to say, an R.F.C. doormat—the blame was laid on me as a matter of course. However, the information supplied by the successful exposures pleased the staff people at whose instigation the deed was done, and this was all that really mattered.
I have already told you that our main work in umpty squadron is long reconnaissance for G.H.Q. and offensive patrol. Special photographic stunts such as happened to-day are rare, thank the Lord. But our cameras often prepare the way for a bombing expedition. An observer returns from a reconnaissance flight with snapshots of a railhead, a busy factory, or an army headquarters. Prints are sent to the "I" people, who, at their leisure, map out in detail the point of interest. No fear of doubtful reports from the glossed surface of geometrical reproduction, for the camera, our most trusted spy, cannot distort the truth. Next a complete plan of the chosen objective, with its surroundings, is given to a bombing squadron; and finally, the pilots concerned, well primed with knowledge of exactly where to align their bomb-sights, fly off to destroy.
For the corps and army squadrons of the R.F.C. photography has a prominent place in the daily round. To them falls the duty of providing survey-maps of the complete system of enemy defences. Their all-seeing lenses penetrate through camouflage to new trenches and emplacements, while exposing fake fortifications. The broken or unbroken German line is fully revealed, even to such details as the barbed wire in front and the approaches in rear.
For clues to battery positions and the like, the gun country behind the frontier of the trenches is likewise searched by camera. One day a certain square on the artillery map seems lifeless. The following afternoon an overhead snapshot reveals a new clump of trees or a curious mark not to be found on earlier photographs. On the third day the mark has disappeared, or the trees are clustered in a slightly different shape. But meanwhile an exact position has been pin-pointed, so that certain heavy guns busy themselves with concentrated fire. By the fourth day the new gun-pits, or whatever it was that the Hun tried to smuggle into place unnoticed, have been demolished and is replaced by a wide rash of shell-holes.
