in danger of being outflanked. At this point, the Varangians (mainly Anglo-Saxons who had left England after the Norman Conquest) joined in the pursuit of the Norman right. With their massive battle axes, the Varangians attacked the Norman knights, who were driven away after their horses panicked. The Varangians soon became separated from the main force and exhausted so they were in no position to resist an assault. Guiscard sent a strong force of spearmen and crossbowmen against the Varangian flank and inflicted heavy casualties on them. The few remaining Varangians fled into the church of the Archangel Michael. The Normans immediately set the church on fire, and all Varangians perished in the blaze. Meanwhile, George Palaiologos sortied out of Dyrrhachium, but failed to save the situation. Alexios's ally, Serbian King Constantine Bodin stayed aside with his army, intending to await the outcome of the battle. When the Byzantines were defeated and started to flee, Bodin retreated with his army. The Turks who had been lent to him by the Seljuk Sultan Suleyman I followed Constantine's example. Deprived of his left wing (still in pursuit of the Norman right), Alexios was exposed in the centre. Guiscard sent his heavy cavalry against the Byzantine centre. They first routed the Byzantine skirmishers before breaking into small detachments and smashing into various points of the Byzantine line. This charge broke the Byzantine lines and caused them to rout. The imperial camp, which had been left unguarded, fell to the Normans. Alexios and his guards resisted as long as they could before retreating. As they retreated, Alexios was separated from his guard and was attacked by Norman soldiers. While escaping, he was wounded in his forehead and lost a lot of blood, but eventually made it back to Ohrid, where he regrouped his army. Aftermath The battle was a heavy defeat for Alexios. Historian Jonathan Harris states that the defeat was "every bit as severe as that at Manzikert." He lost about 5,000 of his men, including most of the Varangians. Norman losses are unknown, but John Haldon claims they are substantial as both wings broke and fled. Historian Robert Holmes states: "The new knightly tactic of charging with the lance couched – tucked firmly under the arm to unite the impact of man and horse – proved a battle-winner." George Palaiologos had not been able to re-enter the city after the battle and
