 Complete the following phrase:  The EEF launched its final offensive, the Battle of Megiddo, on 19 September 1918. The DMC was on the coast, massed behind the infantry to exploit the breakthrough. 4th Cavalry Division was launched four hours after Zero at 08.40 and advanced against slight resistance. The division paused after 12 hours, then overran the Turks primitive third line defences. It paused to water the horses in the evening, then moved off again an hour before midnight, riding into the GermanTurkish HQ at Afulah and then heading east to Beisan to cut off Turkish retreat. The division rode in 34 hours. There was still a gap through which the Turks could escape across the River Jordan, and on 23 September 11th Cavalry Brigade was ordered to ride south down both banks of the river to cut off this route. It encountered the HQ elements of the German Asia Corps at Makhadet abu Naji; after a fight the cavalry charged to seal off both sides of the ford, capturing 4000 prisoners. The following morning the brigade completed the closure of the net by seizing the fords at Makhadet el Masudi and gathering another 5000 prisoners. 4th Cavalry Division now turned north to cooperate with the Arab Northern Armys advance on Damascus. The men were beginning to suffer from malaria, influenza and hunger, and the advance slowed, but on 30 September 11th Brigade was pushed on ahead and caught up with Col T.E. Lawrence and the Arab irregulars attacking the Turkish rearguard. Lawrence asked for help, and was sent the Middlesex Yeomanry and the Hampshire Royal Horse Artillery. The gunners fired over open sights until darkness fell, then the Yeomanry and Arabs charged the Turks in the rear, forcing them into the Arab trap.
