SPRING AND SUMMER TRENCH WAR ON THE TIGRIS
After the surrender of Kut-el-Amara a lull of a few weeks occurred. The Turkish forces seemed to be satisfied for the time being with their victory over their English opponents for which they had striven so long. The English forces below Kut-el-Amara likewise seemed to have ceased their activities as soon as the fall of Kut had become an established fact.
Almost for three weeks this inactivity was maintained. On May 19, 1916, however, both sides resumed military operations. The Turks on that day vacated an advanced position on the south bank of the Tigris at Beit Eissa, which formed the southern prolongation of the Sanna-i-Yat position. On the north bank the latter was still held strongly by the Sultan's forces.
Immediately following this move the English troops, who under General Sir Gorringe had attempted the relief of Kut-el-Amara, attacked. Advancing about three miles south of the Tigris and south of the Umm-el-Brahm marshes, they threw themselves against the southern end of the Turkish position at Es-Sinn. The latter is about seven miles west of the former and about the same distance east of Kut-el-Amara. It began on the north bank of the Tigris, a few miles north of the Suwatcha marshes, continued between these and the Tigris and for almost five miles in a southeasterly direction. On its southern end the Turks had erected a strong redoubt, known under the name Dujailar Redoubt, from which a strong line of six lesser redoubts run in a southwesterly direction to the Shatt-al-hai. This body of water is the ancient bed of the Tigris. In the first half of the year it is a navigable stream, carrying the waters of the Tigris across the desert to the Euphrates near Nasiriyeh, a town which British forces have held since the spring of 1915. It was against the key of this very strong line of defense, the Dujailar Redoubt, which General Gorringe's battalions attacked. At various other times before English troops had attempted to carry this point, but had never succeeded. This time, however, they did meet with success. In spite of strong resistance they stormed and carried the position.
On the same day, May 19, 1916, it was officially announced that a force of Russian cavalry had joined General Gorringe's troops. This cavalry detachment, of course, was part of the Russian forces operating in the region of Kermanshah in Persia. Inasmuch as these troops were then all of 200 miles from Kut-el-Amara and had to pass through a rough and mountainous country, entirely lacking in roads and inhabited by hostile and extremely ferocious Kurdish hillmen, the successful dash of this cavalry detachment was little short of marvelous. The difficulties which had to be faced and the valor which was exhibited is interestingly described by the official British press representative with the Mesopotamian forces:
"The Cossacks' ride across country was a fine and daring achievement, an extreme test of our Allies' hardness, mobility, and resource. Their route took them across a mountainous territory which has been a familiar landmark in the plains where we have been fighting for the last few months.
"The country traversed was rough and precipitous and the track often difficult for mules. They crossed passes over 8,000 feet high. Enemy forces were likely to be encountered at any moment, as these hills are infested with warlike tribes, whose attitude at the best might be described as decidedly doubtful.
"Their guide was untrustworthy. He roused their suspicions by constant attempts to mislead them, and eventually he had to point the way with a rope round his neck. Nevertheless, they met with no actual opposition during the whole journey other than a few stray shots at long range.
"They traveled light. For transport they had less than one pack animal for ten men. These carried ammunition, cooking pots, and a tent for officers. Otherwise, beyond a few simple necessaries, they had no other kit than what they stood up in, and they lived on the country, purchasing barley, flour, rice, and sheep from the villagers. Fodder and fuel were always obtainable.
"For ambulance they had only one assistant surgeon, provided with medical wallets, but none of these Cossacks fell sick. They are a hard lot.
