The Battle of Jarrab was a territorial battle between the Al Saud and their traditional enemies, the Al Rashid on 24 January 1915. It was a proxy battle of World War I and the Second Saud-Rashidi War between the British-supported Saudis and the Ottoman-supported Rashidis.
Rashidi forces led by young Saud bin Abdulaziz Al Rashid defeated the forces of Ibn Saud. The main significance of the battle was the death of Ibn Saud's British Military Advisor, Captain William Shakespear. The battle is also remembered in some historical and tribal accounts for the bravery of Matni bin Shraim and his men, whose steadfast resistance and fierce fighting are said to have played a decisive role in turning the tide of the battle in favor of the Rashidi forces. While some sources attribute Ibn Saud’s defeat primarily to the withdrawal of the Ajman tribe led by Dhaydan bin Hithlain, other accounts emphasize the significant contribution of Matni bin Shraim and his companions in securing the Rashidi victory.
The defeat and the death of William Shakespear diminished the relationship between Ibn Saud and the British, changing the course of the Arab Revolt against the Ottoman Empire. It also resulted in other negative conclusions for Ibn Saud, including a year-long struggle with the Ajman tribe, namely the Battle of Kanzan, and the decrease in his newly emerged prestige.
