Battle of Tours
The Muslim leader, Emir Abd er Rahman was killed and the Muslims retreated to Spain, where it would take over 700 more years for the Christians to reconquer. Muslims refer to the Battle of Tours as the "Court of Martyrs". It is referred to as the Battle of Poitiers in France. (In truth, the battle happened between Poitiers and Tours - the Moors had burnt and left Poitiers, when Martel met them on their way to Tours).
(Referring to this engagement as the "Battle of Tours" removes any chance of confusing it with the Battle of Poitiers between France and England in 1356.)
