On June 18, 860,[3] at sunset, a fleet of about 200 Rus' vessels[4] sailed into the Bosporus and started pillaging the suburbs of Constantinople (Old East Slavic: Tsarigrad, Old Norse: Miklagarðr). The attackers were setting homes on fire and drowning and stabbing the residents. Unable to do anything to repel the invaders, Patriarch Photius urged his flock to implore the Theotokos to save the city.[5] Having devastated the suburbs, the Rus' passed into the Sea of Marmora and fell upon the Isles of the Princes, where the former Patriarch Ignatius of Constantinople was in exile at the time.
