The Battle of Jabal Shammar, or Battle of Umm Radh'ma (Arabic: مَعْرَكَة أُمّ رَضْمَة, romanized: Maʿrakat Umm Raḍmah), took place on August 1929, between a raiding rebellious Ikhwan party and the ally tribes of Ibn Saud. It was the second largescale engagement of the Ikhwan Revolt in Arabia. The rebel Ikhwan tribesmen were defeated by the pro-Saudi forces.
After the defeat in Sabillah, Ikhwan tribesmen and government troops clashed again in the Jabal Shammar region, on August 1929, resulting in the deaths of some 1,000 men.[1]
According to Ibn Saud Information Resource, the battle, fought between Ikhwan raiders under command of Azaiyiz, son of Faisal al-Dawish, and the Saudi forces of Shammar tribesmen, under the leadership of Nida bin Naheer, was "furious" and "many fell".[2] The Ikhwan movement suffered many more casualties than the Shammer, and Nida from the Shammar fell in the battle.[2]
