With the end of the rains and the rapid approach of summer came a period of sheer torment for our troops in the Jordan Valley. The mud changed to a fine, powdery dust, which rose in clouds at the slightest movement, myriads of flies awoke from their long winter sleep, and clouds of mosquitoes arrived for their annual feast. Drill shorts, which formerly had been the general summer wear, were now strictly forbidden to the mounted troops, who were forced to endure the sticky agony of riding-breeches every hour of the twenty-four in order to expose as little as possible of their persons to the unremitting attacks of these pestilential insects. Also, the bivouac areas were infested with small but poisonous snakes who had, like scorpions, a fondness for army blankets; and it is no exaggeration to say that a man went to sleep every night with the full consciousness that he might never wake again. Finally, as if these inflictions were not enough, droves of Turkish aeroplanes came over daily and scientifically bombed all the camps in the valley. The camels in particular made an excellent mark and suffered severely, though apart from this, they were the only living creatures appertaining to the army who flourished and waxed fat in that blistering lime-kiln.
Towards the end of April a heavy concentration of cavalry round Jericho made it evident that another attempt was to be made east of the Jordan, and on the night of the 28th-29th the 1st Australian Mounted Division crossed the river and advanced due north, between the east bank and the foothills, towards the Turkish road from Nablus to Es Salt and the ford known as Jisr ed Damieh, whence they were to march east for the purpose of cutting off the retreat of the garrison at Shunet Nimrin should the attack of the 60th Division on that place prevail. Soon after dawn the cavalry came under very heavy fire, but pushed forward and attained their objectives, where two brigades, without artillery, went off to help the Londoners. The latter marched all night, and, taking the Turks by surprise in the early hours, stormed part of the pass, but despite all their efforts could make no further headway.
Meanwhile the 4th Light Horse and a brigade of horse-artillery were heavily engaged till dusk in holding off reinforcements from Nablus who were attempting to cross by the Jisr ed Damieh ford. After nightfall this brigade and the batteries retired a short distance and took up a position commanding the road, in a deep wadi where the guns had to be man-handled into place, after which the waggons and limbers were let down the sides of the wadi by means of drag-ropes, and the horses scrambled down as best they could. Dawn brought the news that the Turks had successfully crossed the Jordan during the night, and had followed the river southwards in the direction of our second bridgehead at El Auja, intending to come at the left flank of the Light Horse, which was absolutely in the air.
At seven o'clock they attacked, and plastered the batteries in the wadi with shells till, at the end of two hours, the position became untenable, and an attempt was made to shift the guns. It was incomparably more difficult to get out of the wadi than it had been to get in, and moving was but out of the frying-pan into the fire, for one wadi led into another, and the sides were so precipitous that the horses were almost useless for dragging out the guns. Four teams were hooked into a gun, but the ground made it impossible for more than half a dozen horses at a time to be in draught, and when at last the position was cleared the horses slithered down the sides of the wadis, and guns and waggons overturned at the bottom in hopeless and inextricable confusion.
Frantically the gunners strove to get them out, some harnessing themselves to the drag-ropes and others shoving on the wheels; but every effort was to no purpose, and meanwhile horses and men were being shot down on all hands by the advancing Turks, whose cries of "Allah! Allah!" could now be plainly heard. At last the inevitable order was given to clear out with such horses as remained, for it was impossible to move, much less save the guns, and after these had been rendered useless to the enemy, the gallant gunners reluctantly withdrew.
The moment they were clear of the foothills they galloped into an inferno of machine-gun fire at close quarters from the Germans and Turks occupying wadis and shell-holes all over the plain. Horses were shot down right and left, and a team of eight which had not been unhooked were all hit, together with two of the drivers, who fortunately managed to get safely away. Finally the shattered remnants of the artillery brigade assembled at Ghoraniyeh bridgehead, while the Light Horse fell back towards Es Salt, which the other two brigades had succeeded in occupying. By their clever manœuvring, however, the Turks had rendered the position both of the Australians in Es Salt and the 60th Division in front of Nimrin so precarious that another withdrawal was urgently necessary, and after the Londoners had made a last desperate attempt to storm the pass, the retirement was carried out successfully and without loss, though in bitter disappointment at a second failure; that it was the only time in the whole campaign when British guns were captured by the Turks was remarkably poor consolation.
