Igor's successor Svyatoslav seemed to have been on better terms with Sveneld, who was the second in command during his campaigns in Bulgaria and Byzantium. In 971, he was in charge of the defense of Preslav against the Greeks. Although the Byzantine historians John Skylitzes and Leo the Deacon testify that Sphangel (as he was known to them) met his death at Dorostolon the same year, the Slavonic chronicles mention Sveneld's activities several times thereafter.
