That early morning, was repeated in the neighbourhood of Shaiba the action which the Indian Expeditionary Force had fought on its way to Kurnah; for the troops advanced over the open, there being not a vestige of cover, while the cavalry manoeuvred towards the flank of the enemy; a guard of Arab horsemen, and amongst them the chief whose acquaintance we have already made, supporting the regular cavalry and making ready for a dash upon the enemy. To hardened campaigners, as Geoff and Philip had now become, the roar of guns, the splash of shells, and the detonations about them made hardly any difference; they were as cool as cucumbers, and went on with their work as though nothing were happening. And gradually, as the hours flew on, Indian and British--those gallant troops who had invaded Mesopotamia--advanced upon the Turks by little rushes, advanced, and then lay down, throwing up a parapet of sand in front of them to give them some protection, while British guns thundered in the rear and plumped shells into the Turkish trenches. And then that long blast was repeated, that shout down the line of attacking troops, the shrill shriek of officers' whistles, and the charge which was to carry our men into the enemy's position had begun. With those shouts there mingled the shrieks of hundreds of Arab horsemen--those excited individuals manoeuvring at that moment towards the flank of the Turkish trenches. Their shrill cries could be heard right across the field of battle, while their robed figures, their waving arms, and their gesticulations could be observed from the far distance. Waiting till the British troops had plunged into the Turkish trenches, and until the enemy were broken and were fleeing, the Arabs burst like a bolt towards the open, and, swinging in behind those trenches, went charging amongst the enemy, cutting them down, shouting as they rode, riding over the unfortunate subjects of the Sultan and those scheming German officers who had come to train the enemy. One moment there was Bedlam--shouts and shrieks, the rattle of rifles, the sharp splutter of machine-guns and the deeper roar of cannon--and the next there was almost complete silence, save for the distant calls of those fierce Arab horsemen wreaking vengeance upon the Turks. "And now commences the march on Amara," Geoff was able to tell his friend a few days later. "We've got the Turks running, and I expect the G.O.C. will make the most of it. A sharp and rapid advance might allow us to capture Amara with little opposition, and then we should be firmly posted on the river and able to take up a defensive position."
