Shaiba
Following British successes at Basra in November and Qurna
in December 1914, the Turkish forces under Colonel Subhi Bey had been driven up the Tigris to Ruta where they remained.
A second Turkish force separately crossed the Tigris into pro-British but neutral Persia.  To their west, at Nasiriyeh on the River Euphrates, a third force comprising 12,000 Turks with over 10,000 Arabs assembled for an attack on the British HQ at Basra.
The British were themselves reinforcing Basra from India.  However despite possessing numerical supremacy (with a combined force of approximately 30,000 men) the British force suffered from a want of equipment and supplies (notably water).
The Turks initiated their offensive with bombardments of Shaiba and Qurna on 11 April 1915.  The bombardment of the British 6th (Poona) Division progressed for three days while periodic attempts at piercing the town's defences were unsuccessfully attempted; eventually a counter-attack by the 2nd Battalion, The Dorsetshire Regiment  and 24th Punjabi Regiments routed the Turks with heavy losses.
However, the Turks' main effort was at Shaiba. On 13 April, two days after the bombardment of the town started, Turkish troops attempted to outflank the British while the Turkish cavalry prepared for a frontal assault. The intervention of two British Infantry battalions rapidly dispersed the Turk cavalry, resulting in their withdrawal into nearby woods which were secured by the British following an infantry battle throughout 14 April.
Casualties during the woodland battle were heavy: the Turks incurred around 2,400 casualties, and the British around half that number.  Some 5,000 troops on each side were involved in the fighting.
