The battle of the Indus River was fought on November 24, 1221, between Jalal ad-Din Mingburnu, Shah of the Khwarezmid (Quran) Empire, and a Mongol army of about 5 tumen (50,000 men). In confronting the Mongol warfare of the time — for fluidity (disappearing into space) and swiftness (space versus time) — the main objective in the battle was not to lose it, to demonstrate value and to force the invader to abandon the territory of his interest. Beating and / or destroying them in a single encounter at the height of the Mongol wave was unlikely for most world armies. In the simulation of the Battle of the Indus River we will test the Persian Mamluk army by adopting a concave battle order, which has its best use in the situation where a defense initially yields, intentionally or unintentionally, its center.
