The decisive battle of Manzikert, which it is not too much to call the turning-point of the whole course of Byzantine history, was fought in the early summer of 1071. For a long day the Byzantine horsemen continued to roll back and break through the lines of Turkish horse bowmen. But fresh hordes kept coming on, and in the evening the fight was still undecided. As the night was approaching, Romanus prepared to draw his troops back to the camp, but an unhappy misconception of orders broke up the line, and the Seljouks edged in between the two halves of the army. Either from treachery or cowardice Andronicus Ducas, the officer who commanded the reserve, led his men off without fighting. The Emperor’s division was beset on all sides by the enemy, and broke up in the dusk. Romanus himself was wounded, thrown from his horse, and made prisoner. The greater part of his men were cut to pieces. [Illustration] Nicephorus Botaniates Sitting In State. (_From a contemporary MS._) (_From "L’Art Byzantin." Par Charles Bayet.

It is true that Romanus was led after his capture to the tent of the Sultan, and laid prostrate before him, that, after the Turkish custom, the conqueror might place his foot on the neck of his vanquished foe. But after this humiliating ceremony the Emperor was treated with kindness, and allowed after some months to ransom himself and return home. He would have fared better, however, if he had remained the prisoner of the Turk. During his captivity the conduct of affairs had fallen into the hands of John Ducas, uncle of the young emperor Michael. The unscrupulous regent was determined that Romanus should not supersede him and mount the throne again. When the released captive reappeared, John had him seized and blinded. The cruel work was so roughly done that the unfortunate Romanus died a few days later.
