In the meantime the infantry, driving before them the demoralised remnants of the Turkish 8th Army, captured Tul Keram, Turkish G.H.Q., together with a host of prisoners, and then continued east to help the Welsh and Irish divisions in their assault on Nablus. The Turks here had no information of the débâcle on their right, for the R.A.F. had started out at dawn and had destroyed every means of communication, except the roads, between the two armies. They therefore fought with the utmost determination, and aided by their well-chosen and well-fortified positions, held off our attacks all that day and the next, though the Irishmen by extraordinary exertions crumpled up one flank. Then the last message ever sent from the north informed them that the British cavalry had overrun the whole country in their rear, so far as they knew the only line of retreat left open to them was eastward across the Jordan, and this loophole, too, was soon to be closed. Panic reigned; the roads leading east were black with long columns of guns and transport and men mingled in hopeless confusion, fleeing with no thought of anything but their own safety; a routed, utterly demoralised rabble.
Nablus was occupied without difficulty on the 21st, but the infantry, who had been scrambling about the hills of Samaria for three days, could not run fast enough to catch the Turks, who were making their way through the Wadi Farah towards the Jisr ed Damieh ford. Half-way through the wadi the road has on one side a deep, gloomy gorge, while on the other stretch gaunt hills terrible in their desolation and stony barrenness. The whole aspect of the place is sinister and forbidding in the extreme, and one can imagine the panic-stricken Turks hurrying through yet a little faster, eager to sight the yellow waters of the Jordan. But they never reached the goal, for the Royal Air Force found the column half-way through the gorge. Relays of machines joined in the attack, first dropping bombs and then flying low and spraying the column with bullets. In five minutes the road eastwards was blocked, and driven by the slow but remorseless advance of our infantry far in the rear, with impassable hills on the one hand, and a precipice on the other, the column was caught in a trap.
