The Battle of Hunayn
A battle in a valley near Mecca against the tribes of Hawazin and Thaqif, shortly after the conquest of Mecca. The Muslims were ambushed in the valley's gorges and fell back at first; the Prophet ﷺ stood firm and they rallied, as the sira tradition records. The Encyclopaedia of Islam puts the Muslim force at twelve thousand and the Muslim dead at about twelve, and notes that the accounts of the battle differ by school.
