Seven Pillars of Wisdom by T.E. Lawrence — Read

Quietly we regained our camels and slept. Next morning we returned on our tracks to let a fold of the plain hide us from the railway, and then marched south across the sandy flat; seeing tracks of gazelle, oryx and ostrich; with, in one spot, stale padmarks of leopard. We were making for the low hills bounding the far side, intending to blow up a train; for Zaal said that where these touched the railway was such a curve as we needed for mine-laying, and that the spurs commanding it would give us ambush and a field of fire for our machine-guns.

So we turned east in the southern ridges till within half a mile of the line. There the party halted in a thirty-foot valley, while a few of us walked down to the line, which bent a little eastward to avoid the point of higher ground under our feet. The point ended in a flat table fifty feet above the track, facing north across the valley.
