 Thomas exploited this small victory for all it was worth, widely proclaiming that he had defeated Michael's troops "by land and sea". He sent messages to the themes of Greece, whose support had been lukewarm until that point, demanding additional ships. The themes responded forcefully, sending their squadrons, allegedly numbering 350 vessels, to join him. Thus reinforced, Thomas decided to launch a two-pronged assault against Constantinople's sea walls, with his original fleet attacking the wall of the Golden Horn, and the new fleet attacking the south coast, looking towards the Sea of Marmara. Michael, however, did not remain idle: his own fleet attacked the thematic force soon after it arrived at its anchorage in Byrida. Using Greek fire, the Imperial Fleet destroyed many of the rebel vessels and captured most of the remaining ships. Only a few managed to escape and rejoin Thomas's forces.
