The crusaders set up a commission to distribute the Byzantine territories among them in September. In Asia Minor, the "duchy of Nicaea" was granted to Louis I, Count of Blois, and the "duchy of Philadelphia" to Stephen of Perche, although the Latins had not conquered these lands. The Venetians seized the port of Lampsacus on the Asian side of the Hellespont and a French knight, Peter of Bracieux, captured the nearby Pegai. Emperor AlexiosI of Trebizond's brother and co-emperor, David Komnenos, launched a military campaign into Paphlagonia and occupied the towns along the Black Sea coast. His conquest facilitated Bracieux's invasion of Bithynia. He routed Theodore at Poemanenum on 6December. After his victory, Bracieux seized Bithynian forts.
