The arch was solid masonry, of four metres span, and stood over a shingle water-bed which took its rise on our hill-top. The winter rains had cut this into a channel four feet deep, narrow and winding, which served us as an admirable approach till within three hundred yards of the line. There the gully widened out and ran straight towards the culvert, open to the sight of anyone upon the rails.
We hid the explosive carefully on the crown of the arch, deeper than usual, beneath a tie, so that the patrols would not feel its jelly softness under their feet. The wires were taken down the bank into the shingle bed of the watercourse, where concealment was quick; and up it as far as they would reach. Unfortunately, this was only sixty yards, for there had been difficulty in Egypt over insulated cable and no more had been available when our expedition started.
Sixty yards was plenty for the bridge, but little for a train: however, the ends happened to coincide with a little bush about ten inches high, on the edge of the watercourse, and we buried them beside this very convenient mark. It was impossible to leave them joined up to the exploder in the proper way, since the spot was evident to the permanent-way patrols as they made their rounds.
Owing to the mud the job took longer than usual, and it was very nearly dawn before we finished. I waited under the draughty arch till day broke, wet and dismal, and then I went over the whole area of disturbance, spending another half-hour in effacing its every mark, scattering leaves and dead grass over it, and watering down the broken mud from a shallow rain-pool near. Then they waved to me that the first patrol was coming, and I went up to join the others.
Before I had reached them they came tearing down into their prearranged places, lining the watercourse and spurs each side. A train was coming from the north. Hamud, Feisal's long slave, had the exploder; but before he reached me a short train of closed box-waggons rushed by at speed. The rainstorms on the plain and the thick morning had hidden it from the eyes of our watchman until too late. This second failure saddened us further and Ali began to say that nothing would come right this trip. Such a statement held risk as prelude of the discovery of an evil eye present; so, to divert attention, I suggested new watching posts be sent far out, one to the ruins on the north, one to the great cairn of the southern crest.
The rest, having no breakfast, were to pretend not to be hungry. They all enjoyed doing this, and for a while we sat cheerfully in the rain, huddling against one another for warmth behind a breastwork of our streaming camels. The moisture made the animals' hair curl up like a fleece, so that they looked queerly dishevelled. When the rain paused, which it did frequently, a cold moaning wind searched out the unprotected parts of us very thoroughly. After a time we found our wetted shirts clammy and comfortless things. We had nothing to eat, nothing to do and nowhere to sit except on wet rock, wet grass or mud. However, this persistent weather kept reminding me that it would delay Allenby's advance on Jerusalem, and rob him of his great possibility. So large a misfortune to our lion was a half-encouragement for the mice. We would be partners into next year.
In the best circumstances, waiting for action was hard. To-day it was beastly. Even enemy patrols stumbled along without care, perfunctorily, against the rain. At last, near noon, in a snatch of fine weather, the watchmen on the south peak flagged their cloaks wildly in signal of a train. We reached our positions in an instant, for we had squatted the late hours on our heels in a streaming ditch near the line, so as not to miss another chance. The Arabs took cover properly. I looked back at their ambush from my firing point, and saw nothing but the grey hillsides.
I could not hear the train coming, but trusted, and knelt ready for perhaps half an hour, when the suspense became intolerable, and I signalled to know what was up. They sent down to say it was coming very slowly, and was an enormously long train. Our appetites stiffened. The longer it was the more would be the loot. Then came word that it had stopped. It moved again.
Finally, near one o'clock, I heard it panting. The locomotive was evidently defective (all these wood-fired trains were bad), and the heavy load on the up-gradient was proving too much for its capacity. I crouched behind my bush, while it crawled slowly into view past the south cutting, and along the bank above my head towards the culvert. The first ten trucks were open trucks, crowded with troops. However, once again it was too late to choose, so when the engine was squarely over the mine I pushed down the handle of the exploder. Nothing happened. I sawed it up and down four times.
Still nothing happened; and I realized that it had gone out of order, and that I was kneeling on a naked bank, with a Turkish troop train crawling past fifty yards away. The bush, which had seemed a foot high, shrank smaller than a fig-leaf; and I felt myself the most distinct object in the country-side. Behind me was an open valley for two hundred yards to the cover where my Arabs were waiting and wondering what I was at. It was impossible to make a bolt for it, or the Turks would step off the train and finish us. If I sat still, there might be just a hope of my being ignored as a casual Bedouin.
So there I sat, counting for sheer life, while eighteen open trucks, three box-waggons, and three officers' coaches dragged by. The engine panted slower and slower, and I thought every moment that it would break down. The troops took no great notice of me, but the officers were interested, and came out to the little platforms at the ends of their carriages, pointing and staring. I waved back at them, grinning nervously, and feeling an improbable shepherd in my Meccan dress, with its twisted golden circlet about my head. Perhaps the mud-stains, the wet and their ignorance made me accepted. The end of the brake van slowly disappeared into the cutting on the north.
As it went, I jumped up, buried my wires, snatched hold of the wretched exploder, and went like a rabbit uphill into safety. There I took breath and looked back to see that the train had finally stuck. It waited, about five hundred yards beyond the mine, for nearly an hour to get up a head of steam, while an officers' patrol came back and searched, very carefully, the ground where I had been seen sitting. However the wires were properly bidden: they found nothing: the engine plucked up heart again, and away they went.
CHAPTER LXXVIII
Mifleh was past tears, thinking I had intentionally let the train through; and when the Serahin had been told the real cause they said 'Bad luck is with us'. Historically they were right; but they meant it for a prophecy, so I made sarcastic reference to their courage at the bridge the week before, hinting that it might be a tribal preference to sit on camel-guard. At once there was uproar, the Serahin attacking me furiously, the Beni Sakhr defending. Ali heard the trouble, and came running.
When we had made it up the original despondency was half forgotten. Ali backed me nobly, though the wretched boy was blue with cold and shivering in an attack of fever. He gasped that their ancestor the Prophet had given to Sherifs the faculty of 'sight', and by it he knew that our luck was turning. This was comfort for them: my first instalment of good fortune came when in the wet, without other tool than my dagger, I got the box of the exploder open and persuaded its electrical gear to work properly once more.
