The victory encouraged the Byzantines and dejected the Arabs, who, according to Theophanes, had originally intended to sail to the sea walls the same night and try to scale them using the ships' steering paddles. The same night, Leo drew up the chain between the city and Galata, closing the entrance to the [[Golden Horn]]. The Arab fleet became reluctant to engage the Byzantines, and withdrew to the safe harbour of [[Sosthenion]] further north on the European shore of the Bosporus.<ref>{{harvnb|Guilland|1959|pp=119–120}}; {{harvnb|Mango|Scott|1997|pp=545–546}}; {{harvnb|Lilie|1976|p=128}}; {{harvnb|Treadgold|1997|p=347}}.</ref>
