 He destroyed many of their ships and killed many of the raiders, including Photios, while many others were captured and—especially the Christian renegades among them—tortured to death in various ways.Historian David Pettegrew has cast doubt on the historicity of this event, pointing out that Ooryphas' portage of his fleet over the Isthmus is the first and only such recorded event after the 1st century BC, when the "diolkos" was still active.Given that the portage of entire fleets across the Isthmus was considered even in Antiquity an extraordinary feat, and was hardly possible to be carried out in such short time as to surprise a fleet anchored near Corinth, Pettegrew suggests that Ooryphas' portage and victory must be considered more a literary topos evoking Classical models, specifically Philip V of Macedon's similar action while campaigning against the Illyrians in 217 BC, rather than an actual event.
