Kourkoaus destroys Rus' fleet
İstanbul, TurkeyIn early summer 941, as Kourkouas prepared to resume campaigning in the East, his attention was diverted by an unexpected event: the appearance of a Rus' fleet that raided the area around Constantinople itself. The Byzantine army and navy were absent from the capital, and the appearance of the Rus' fleet caused panic among the populace of Constantinople. While the navy and Kourkouas's army were recalled, a hastily assembled squadron of old ships armed with Greek Fire and placed under the protovestiarios Theophanes defeated the Rus' fleet on June 11, forcing it to abandon its course toward the city. The surviving Rus' landed on the shores of Bithynia and ravaged the defenseless countryside. The patrikios Bardas Phokas hastened to the area with whatever troops he could gather, contained the raiders, and awaited the arrival of Kourkouas's army. Finally, Kourkouas and his army appeared and fell upon the Rus', who had dispersed to plunder the countryside, killing many of them. The survivors retreated to their ships and tried to cross to Thrace under the cover of night. During the crossing, the entire Byzantine navy attacked and annihilated the Rus'.
