 Leaving his wife behind, and accompanied by Michael's half-brother Constantine Komnenos Doukas, Alexios took sail for Asia Minor.His attempt ended in complete failure in the Battle of Antioch on the Maeander in 1211, where Theodore I Laskaris killed Kaykhusraw and took Alexios prisoner.The hagiography of St. Theodora of Arta claims that on his departure, Alexios granted Michael and his descendants hereditary possession of his domain, while the 14th-century Aragonese version of the "Chronicle of the Morea" claims that Alexios left Michael as his lieutenant in the west.
