Andronikos Doukas (or Ioannes the kaisar) turned Byzantine victory to defeat, leaving Romanos IV to be captured

Summary:
Andronikos Doukas, son of the kaisar Ioannes, has been accused of malice in causing the defeat of Romanos IV. He was said to have conceived a plot against Romanos. According to many eye-witnesses, he spread among the soldiers (who saw the imperial standard turning back) the rumour that the emperor had been defeated. He fled at full gallop with his men returning to the camp. Wilder stories implicate kaisar Ioannes himself, who was not present

Andronikos Doukas, son of the kaisar Ioannes (Andronikos 61)
  • Conceived a plot against the emperor (Romanos 4) and, according to many eye-witnesses, spread among the soldiers (who saw the imperial standard turning back) the rumour that the emperor had been vanquished, and fled with his men returning to the camp (:) προβεβουλευμένην ἔχων τὴν κατὰ τούτου ἐπιβουλήν Attaleiates: History 161.18-162.1 / 120.8-13
  • Conceived a plot and when the emperor (Romanos 4) ordered his troops to return from their pursuit of the Turks (near Mantzikert) he spread the rumour that they had been defeated, took his men and fled to the Roman camp followed by all the soldiers (:) προβεβουλευμένην ἔχων τὴν ἐπιβουλήν Skylitzes Continuatus 149.8-13
  • Leaving at once with his men (for he was commanding a not inconsiderable detachment of soldiers), he returned at full gallop to the encampment. This turned the rest also to flight (:) Zonaras 18.14.14
  • Those who had formations somewhere further away suspected that the emperor (Romanos 4)'s turnaround was flight, since he infiltrated the word among the lines (:) Zonaras 18.14.12
Ioannes Doukas, kaisar (Ioannes 62)
  • As the Byzantines were winning the battle of Mantzikert, he was the first to flee from the battle and everyone followed him, deserting Romanos 4; the emperor was left in a trap, like a plucked jackdaw, while the Turkish generals competed for the honour of capturing him alive (:) Manasses, Chronicle 6473-6486
Emperor Romanos IV Diogenes (Romanos 4)
  • As the Byzantines were winning the battle of Mantzikert, Ioannes 62 was the first to flee from the battle and everyone followed him, deserting the emperor; Romanos was left in a trap, like a plucked jackdaw, while the Turkish generals competed for the honour of capturing him alive (:) Manasses, Chronicle 6473-6486
