In 1306 Tedisio campaigned in Thasos, where he captured the castle and made the island his fief.
The new governor, Andriolo Cattaneo, sent his son Domenico against Tedisio, and took over Phocaea.
After a siege he captured the city, but he was unable to keep it under control, and was forced to retreat to Thasos to defend his fief.
The Catalan historian Ramon Muntaner refers in his Chronicle that the raid into the castle of Phokaia allowed Zaccaria to take with him the relics of the Holy Cross, a white shirt made by the Virgin Mary, and a codex with the Apocalypsis, all of them taken after the Turkish conquest into Pholaia from the tomb of Saint John, the author of the Gospel, in Ephesos.
The fragments of the Holy Cross were given to the same Muntaner, as he was the Chancellor of the Catalan Company, while Zaccaria retained the other relics.
