On the day before the main attack, a small advance was carried out by the right wing just west of the Jordan, occupying El Mugheir. This place is the junction of several roads leading from the west to the east of the Jordan. The object of this preliminary move was to prevent the Turks west of the river escaping by this route to the east, and also to draw the attention of the enemy towards the Jordan Valley and distract it from the coastal sector.
By the night of the 18th/19th September, our troops were in position. The Divisions occupying the line from the sea on the left were the 60th, the 7th and the 75th on the Plain, the 3rd where Plain and hills meet about Mejdel Yaba, the 54th and the French at Rafat. Thence the line was held by the 10th Division, assisted by a composite force, and, on the extreme right, about the recently captured Mugheir, by the 53rd. Cavalry were concentrated behind the 60th Division ready to dash forward directly the line should be broken.
At 4.30 on the morning of the 19th September, there suddenly opened an intensive bombardment of the enemy's coastal positions, carried out by all the artillery, trench-mortars and machine-guns that could be concentrated in this small sector, the navy also co-operating. After ten minutes' bombardment, the infantry moved forward and assaulted the enemy's front line positions, which were carried with but little opposition. Thereafter the barrage lifted and crept, being supplemented in places by smoke barrages dropped from aeroplanes. The infantry pushed forward and captured the enemy's second and third lines and strong points in rear. Shortly before seven o'clock, the 60th Division had broken right through the enemy defences by the sea, and had reached, and established a bridge-head at the Wadi Nahr el Falyk, a mile or so behind the enemy line. Engineers and pioneers got to work at once, and in a very short space of time had made roads and bridges through the enemy trench system, and over the Nahr el Falyk, by which cavalry and guns could be pushed forward. At 7.30, the cavalry passed through on their dash for the tactical points behind the enemy's lines.
Meanwhile, all along the line our infantry had taken their first objectives with little opposition, the enemy having been taken completely by surprise. The whole line advanced to a maximum depth of 5 miles, and then swung to the right, pivoting on Rafat. Such opposition as was encountered was met with at the strong points well behind the front line, where the enemy had had the time and opportunity to man his defences. For example, both at El Tireh and at Kalkilieh, stubborn resistance was encountered. Thus the line swung right-handed into the hills, crumpling up the whole enemy line west of Rafat. The 60th Division, after their break through, marched for the greater part of the day, and, by 5.30 in the afternoon, had reached Tul Keram. Our line, that evening, ran approximately south and north from Rafat to Tul Keram.
The cavalry passing through the gaps broken at the sea and close to Tabsor, pushed rapidly northward along the Coastal Plain. Some of them made for Tul Keram, and, passing thence up the Valley towards Nablus, had already reached Anebta before dark, cutting off large bodies of the retreating enemy with guns and transport between Tul Keram and the railway junction at Messudieh. Another strong cavalry force moved farther north. They passed through the mountains east of Mount Carmel that night, by the Musmus Pass (Megiddo), and, early on the following morning, the 20th, they charged the enemy holding the northern exit of the Pass and debouched on to the Plain of Esdraelon (Armageddon).
These seized the railway junction at El Afule. Some pushed on eastwards towards the Jordan and captured Beisan (Bethshan), some northwards and captured Nazareth, while some, turning southwards, took Jenin in reverse. By nightfall on the 20th all these tactical points were in our possession.
Yet another exploit remains to be chronicled. Far away across the eastern desert, but beautifully co-ordinated, and working as part of one great machine, moved a raiding force of the Arab troops of Hussein, King of the Hejaz. At the critical moment these swooped down upon the junction at Deraa, where they destroyed the railway in all directions, completely depriving the enemy of their main line of retirement.
Throughout the operations our airmen had the time of their lives. Some hovered all day over the enemy aerodrome at Jenin, and effectually prevented enemy machines from leaving the ground. Some maintained contact between the infantry and the higher command. Some, flying low, bombed and machine-gunned the retreating Turks, and completed their confusion.
The advance was continued on the 20th. On this day, the 10th Division, which had hitherto remained stationary to the right of Rafat, moved forward in a north-easterly direction, taking in rear the strong enemy position at Furkha. The whole line was now advancing and driving the retreating Turks towards Samaria and Nablus, and down the roads leading northwards and eastwards from these points. By the evening of the 20th, the Turkish resistance had collapsed everywhere on the west of the Jordan, except on the Turkish left in the Jordan Valley. Our right wing had advanced slightly, and occupied a line from near El Mugheir to Es Sawieh, while our left wing had swung round and reached the line Bidich-Baka-Messudieh Junction—that is to say, we were gradually closing in on Nablus from the south, south-west, and west. Owing to the tactical positions behind the enemy lines having been seized by our cavalry, all avenues of escape which might have been open to the enemy had been closed, except the fords across the Jordan between Beisan and Jisr-ed-Damieh.
By the 21st, the retreating Turks had become a demoralized rabble, fleeing to the fords of the Jordan, like the discomfited Midianites, under Oreb and Zeeb, had fled more than three thousand years before from the pursuit of Gideon. Those who fled down the northward road were captured and collected by our cavalry at Jenin. Those who fled down the eastward road by the Wadi Fara, hoping to reach the still open ford at Jisr-ed-Damieh, met with a more cruel fate. This road led down a steep and narrow gorge, dominated by the heights east of Nablus. A brigade of the 10th Division was rushed forward by a forced march, and seized these heights, effectually closing the trap. Our airmen had already got the situation well in hand here, and the road soon became a veritable shambles. The enemy had been forced or shepherded by our infantry into this bottle-neck, and our airmen, swooping down to 200 feet and bombing the head of the column, soon made the road impassable. That accomplished, they flew up and down the struggling column, bombing and machine-gunning without let or hindrance. It seemed as though the unspeakable Turk had at last been delivered over to vengeance in this Valley of Death. An eye-witness[11] describes the scene.
