Peter Thomas, who had become patriarch of Constantinople in 1364, is one of the chief promoters of the crusade of 1365.

Peter, having collecting money and mercenaries in western Europe, leads a mixed Cypriote and Western force of Crusaders against Alexandria on October 11, 1365, subjecting the city to a horrible sack and massacre.

Mézières, who accompanies the king to Alexandria, receives the government of a third part of it and a promise for the creation of his order, but the European knights, satisfied by the immense booty, refuse to follow Peter in attacking Cairo, and the king is obliged to return to Cyprus, the only permanent result of his expedition being the enmity of the Mamluk sultan of Egypt.

Peter's unruly crusaders return to Cyprus with immense booty.

Pierre plans to return to Egypt, but no European aid is forthcoming.
