 The brothers defeated the fugitive emperor (July 476) and blockaded him on a hill ironically named "Constantinople" by the locals.Illus also captured Zeno's brother, Longinus, as a tool to keep Zeno under control.During the blockade, Illus and Trocondus were secretly encouraged by the Senate in Constantinople to support Zeno against Basiliscus, with whom they had had a falling-out; Illus himself was discontent with the usurper for permitting the killing of the Isaurians who remained in the capital after Zeno's flight.
