A study of the Hattin campaign analyzes battlefield dynamics, strategic misjudgments, and the collapse of Crusader cohesion that led to Jerusalem's rapid fall.

On 4 July 1187, beneath the scorching sun near the Horns of Hattin, the fate of the Latin Kingdom of Jerusalem was sealed. What began as a desperate march to relieve Tiberias ended in one of the most catastrophic defeats in medieval military history. Within weeks, Jerusalem itself, the spiritual and political heart of the Crusader world, would fall to Saladin.

Under the Burning Sun provides a compelling, thoroughly researched account of that campaign, outlining the series of strategic miscalculations, logistical failures, and command decisions that resulted in the Crusader army's destruction. Special focus is given to the battlefield dynamics of Hattin: the influence of terrain and water, the tactics of harassment and encirclement employed by Ayyubid forces, and the collapse of Crusader cohesion under sustained pressure.

At the centre of the drama stand the Knights Templar, the elite shock troops of the Latin East. Renowned for their discipline and ferocity, at Hattin they faced their greatest defeat. The destruction of the Templar contingent, culminating in mass capture and execution, marked not only a military disaster but also a profound symbolic rupture, shattering the martial prestige of the Crusader orders.

Moving beyond legend and moralised narratives, Under the Burning Sun examines Hattin as a turning point in medieval warfare and Near Eastern geopolitics. By connecting battlefield defeat to the swift conquest of Jerusalem, it demonstrates how a single day of combat reshaped the balance of power in the Levant and changed the course of the Crusades forever.
