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.
