Negotiations followed at Mesembria, and proved successful: not only was peace agreed upon, but the links between Byzantium and Bulgaria were to be strengthened by a dynastic marriage of Tsar Peter with Maria Lekapene, the Byzantine emperor's granddaughter.
[7] Soon, however, Theophanes would have the chance to acquire military glory as well: in early summer 941, the Byzantines received word from Bulgaria that a Rus' fleet of some 1,000 ships was sailing towards the Bosporus and Constantinople.
At that point, the Byzantine capital was well-nigh defenceless, for the imperial army was fighting in the east under John Kourkouas and the navy was engaged with the Arabs in the Mediterranean.
[8] Fifteen old chelandia were discovered in one of Constantinople's harbours, put in order, outfitted with siphons for the discharge of Greek fire, and placed under the command of Theophanes.
[10] At the same time, Kourkouas's victories in the East brought not only new territory to the Byzantine Empire: in 944, he forced the city of Edessa to surrender one of the holiest of Christendom's relics, the "Mandylion".
[12] Theophanes was one of the few officials of the previous regime to remain in power; soon, however, he plotted together with the Patriarch of Constantinople Theophylaktos Lekapenos to return Romanos from his exile and restore him to the Byzantine throne.
