We did not reach the railway till after ten o’clock at night, in conditions of invisibility which made it futile to choose a machine-gun position. At random I pitched upon kilometre 1,121 from Damascus for the mine. It was a complicated mine, with a central trigger to fire simultaneous charges thirty yards apart: and we hoped in this way to get the locomotive whether it was going north or south. Burying the mine took four hours, for the rain had caked the surface and rotted it. Our feet made huge tracks on the flat and on the bank, as though a school of elephants had been dancing there. To hide these marks was out of the question, so we did the other thing, trampling about for hundreds of yards, even bringing up our camels to help, until it looked as though half an army had crossed the valley, and the mine-place was no better and no worse than the rest. Then we went back a safe distance, behind some miserable mounds, and cowered down in the open, waiting for day. The cold was intense. Our teeth chattered, and we trembled and hissed involuntarily, while our hands drew in like claws.
