At dawn, Saladin, commanding the centre on horseback, accompanied by his young son Afdal, and protected as always by his bodyguard of devoted Turkish mamluks (slave-soldiers), started his attack, showering the Franks with arrows and directing the charges of his cavaliers and horse-archers to keep the heavily armoured Franks at bay. For Guy, everything depended on maintaining the shield of infantry around his mounted knights; for Saladin, everything depended on separating them.
As the Bishop of Acre raised the True Cross before the king, Guy’s army repelled the first charges, but soon the thirsty Frankish soldiers fled to higher ground, leaving the knights exposed. Guy’s knights launched their charges. As Raymond of Tripoli and Balian of Ibelin galloped towards the sultan’s forces, Saladin simply ordered his nephew Taki al-Din, commanding the right wing, to open his ranks: the Crusaders galloped through. But the Muslim ranks closed again, tightening the net. Their archers, mostly Armenians, picked off the Frankish horses with ‘clouds of arrows like locusts’, stranding the knights, and ‘their lions became hedgehogs’. On that ‘burningly hot day’, unhorsed and exposed, swollen-mouthed with thirst, tormented by the infernal brushwood, unsure of their leadership, Guy’s soldiers perished, fled or surrendered as his order of battle disintegrated.
He retreated to one of the Horns and there pitched his red tent. His knights surrounded him for a last stand. ‘When the Frankish king had withdrawn to the hilltop,’ recalled Saladin’s son Afdal, ‘his knights made a valiant charge and drove the Muslims back upon my father.’ For a moment, it seemed as if Frankish courage would threaten Saladin himself. Afdal saw his father’s dismay: ‘He changed colour and pulled at his beard then rushed forward crying, “Give the devil the lie!”’ at which the Muslims charged again, breaking the Crusaders, ‘who retreated up the hill. When I saw the Franks fleeing, I cried out with glee, “We’ve routed them!”’ But ‘tortured by thirst’, they ‘charged again and drove our men back to where my father stood’. Saladin rallied his men, who broke Guy’s charge. ‘We’ve routed them,’ cried Afdal again.
‘Be quiet,’ snapped Saladin, pointing at the red tent. ‘We haven’t beaten them so long as that tent stands there!’ At that moment, Afdal saw the tent overturned. The Bishop of Acre was killed, the True Cross was captured. Around the royal tent, Guy and his knights were so exhausted that they lay in their armour helpless on the ground. ‘Then my father dismounted,’ said Afdal, ‘and bowed to the ground, giving thanks to God with tears of joy.’
Saladin held court in the lobby of his resplendent tent, which was still being pitched as his amirs delivered their prisoners. Once the tent was up, he received the King of Jerusalem and Reynald of Kerak. Guy was so desiccated that Saladin offered him a glass of sherbet iced with the snows of Mount Hermon. The king slaked his thirst then handed it to Reynald at which Saladin said: ‘You’re the one who gave him the drink. I give him no drink.’ Reynald was not offered the protection of Arab hospitality.
Saladin rode out to congratulate his men and inspect the battlefield, with the ‘limbs of the fallen, naked on the field, scattered in pieces, lacerated and disjointed, dismembered, eyes gouged out, stomachs dis-embowelled, bodies cut in half,’ the carnage of medieval battle. On his return, the sultan recalled Guy and Reynald. The king was left in the vestibule; Reynald taken inside: ‘God has given me victory over you,’ said Saladin. ‘How often have you broken your oaths?’
‘This is how princes have always behaved,’ replied the defiant Reynald.
Saladin offered him Islam. Reynald refused disdainfully, at which the sultan sprang up, drew a scimitar and sliced off his arm at the shoulder. The guards finished him off. The headless Reynald was dragged feet first past Guy and thrown out at the tent door.
The King of Jerusalem was led inside. ‘It’s not customary for kings to kill kings,’ said Saladin, ‘but this man crossed the limits so he suffered what he suffered.’
In the morning, Saladin bought all the 200 Templars and Hospitaller knights from his men, for fifty dinars each. The Christian warriors were offered conversion to Islam, but few accepted. Saladin called for volunteers from the Sufi mystics and Islamic scholars, to whom he gave the order to kill all the knights. Most begged for the privilege, though some appointed substitutes out of fear that they would be mocked for bungling the job. As Saladin watched from his dais, this messy and amateurish butchery now destroyed what remained of the might of Jerusalem. The bodies were left where they fell. Even a year later, the battlefield remained ‘covered with their bones’.
