 Left stranded in Thessaly, Alexios was captured by Boniface.The former emperor was initially held in comfortable captivity, but at some point he fell foul of Boniface; sources differ on whether he tried to flee to Michael's domains and was captured by Boniface's knights "en route" or whether Boniface simply came to distrust him as a potential rival focal point for the loyalties of the Greek population.He and his wife were then imprisoned, either in Thessalonica or, according to other sources, in Montferrat.
