9th Bn Royal Warwickshire Regt during the Siege of Kut - From: The Story Of The Royal Warwickshire Regiment - By C. L. Kingsford    

Sheikh Saad. On April 3 they went forward to the front line in readiness for the intended assault, in which they were to take the foremost part. At 4.45 on the morning of April 5 the attack started, the Royal Warwickshire being on the extreme left on the river bank. The position was weakly held and by seven o'clock five successive lines of Turkish trenches had been carried with few casualties. The advance continued till noon, when the battalion dug temporary cover and rested. At nightfall the attack on the next position at Falahiyeh began. The advance had to be made over flat ground, and the Royal Warwickshires coming under heavy fire suffered severely. Nevertheless Falahiyeh was taken by the combined efforts of the 9th Royal Warwickshire and the 9th Worcester, as the climax of the one brilliantly successful day in the attempted relief of Kut. The chief credit rested with the 13th Division, who between dawn and midnight had stormed two whole labyrinths of trenches. The Royal Warwickshire had 7 officers [including Captains Baker and Marshall] and 35 men killed or mortally wounded, and 7 officers and 154 men wounded.

There still lay between the relieving army and Kut two lines of trenches; the first at Sanna-i-yat, on both sides of the Tigris with impenetrable marshes on either flank; and the other on the right bank at Es-sinn, much nearer Kut. On April 9 the 13th Division after a night march attacked Sanna-i-yat, but in face of an appalling fire was eventually driven back. In the fight the Royal Warwickshire had 4 officers and 20 men killed, and 3 officers and 106 men wounded. The 13th Division after a brief rest was then transferred to the southern bank, with a view to an attack on Beit Eissa, a fort somewhat in the rear of the Sanna-i-yat lines. The fort was taken, but the Turks counter-attacked in great force, and during three days (April 17-19), there was more hand-to-hand fighting than in any other battle in Mesopotamia. The Turks made six distinct assaults in mass; yet our line was not broken, and the enemy's losses were heavier than in the two previous battles put together. The losses on our side were also severe; the Royal Warwickshire had 3 officers killed and 4 wounded (one mortally), and of other ranks 18 killed and 68 wounded.

A final attack on Sanna-i-yat on April 23 began successfully; but the ground was flooded, and our men struggling in mud and water were unable to resist the Turkish counter-attack. The attempt to relieve Kut had failed, and on April 29 General Townshend was forced to surrender.In less than a month's fighting the 9th Royal Warwickshire had lost nearly all its officers, and its total strength was now not more than 200. The remnant remained in the redoubt at Beit Eissa till May 22, and then went back to hold a part of the blockhouse line from Sheikh Saad to Sodom. Lieut.-Colonel Gordon had fallen sick on April 24, and after an interval had been succeeded by Lieut.-Colonel G. E. Leman of the 7th North Staffords. At the beginning of October the battalion, which was still very weak, was withdrawn from the line for training at Amara. There Lieut.-Colonel E. D. Henderson of the 7th North Staffords took over the command, and reinforcements brought the battalion up to a good strength.
