For some context :
The Battle of Montgisard was fought between the Kingdom of Jerusalem and the Ayyubid Sultanate on 25 November 1177 at Montgisard, in the Levant between Ramla and Yibna.
The 16-year-old Baldwin IV of Jerusalem, severely afflicted by leprosy, led outnumbered Christian forces against Saladin's troops in what became one of the most notable engagements of the Crusades. The Muslim Army was quickly routed and pursued for twelve miles. Saladin fled back to Cairo, reaching the city on 8 December, with only a tenth of his army.
