The city would thus be cut off from all sources of reinforcement and supply, and, it was hoped, would capitulate without further bloodshed.
On the morning of the 18th the Australian Mounted Division found a force of the enemy entrenched on the hill of Amwas, which stands square in the middle of the pass, just where it debouches into the Vale of Ajalon. The artillery of the division, assisted by some of the guns of the 75th Division, opened a vigorous fire on the enemy on Amwas Hill, to which the Turks made but a feeble reply, while the 3rd A.L.H. Brigade endeavoured to pass through the hills to the north, round the enemy's right flank.
All day the regiments struggled on among the rocks, scrambling up and down the steep hills, and making very slow progress. By four o'clock in the afternoon they had advanced barely five miles, and the order was then given to return, and leave the task to the infantry the next day. The threat to their flank had, however, been enough for the Turks, who retired during the night, abandoning four guns, the teams of which had been killed by the fire of the R.H.A.
There had been no fighting to speak of, but the action was of great interest from the associations of the place. From its position in the mouth of the valley, Amwas is, and always has been, the key of the pass to Jerusalem. Who holds this hill holds the city. From the earliest ages, all the armies that have sought to take Jerusalem have passed this way, save only that of Joshua. Philistine and Hittite, Babylonian and Assyrian, Egyptian and Roman and Greek, Frankish Knights of the Cross, all have passed this way, and all have watered the hill of Amwas with their blood.
The Australian Mounted Division handed over the further advance to the 75th Division next day, and withdrew to the mouth of the Nahr Sukereir, to get grazing for its horses. Two days later the division marched back to El Mejdel, in order to relieve the supply situation. Our broad-gauge railway had now nearly reached this place, and it was possible to draw supplies direct from railhead with the divisional train.
The 8th and 22nd Brigades of the Yeomanry Division plunged into the hills on the morning of the 18th, and soon found themselves in difficulties. In this mountain country, in which there were no wheeled vehicles, and all goods were carried on the backs of donkeys, what was known to the natives as a good road was usually little more than a goat track, winding in and out among the boulders. As far as Beit Sira there was some semblance of a road, though, even on this portion of it, the gunners were at work all day removing the biggest of the boulders from the path, before their guns could pass. Beyond Beit Sira the road was nothing but the merest footpath, leading straight down and up the numerous deep and narrow ravines that intersect the country in all directions. Sometimes it required half an hour's reconnaissance to move forward half a mile.
