Battle of Halmyros
The Battle of Halmyros, known by earlier scholars as the Battle of the Cephissus or Battle of Orchomenos, was fought on 15 March 1311, between the forces of the Frankish Duchy of Athens and its vassals under Walter of Brienne against the mercenaries of the Catalan Company, resulting in a decisive victory for the Catalans.
Engaged in conflict with their original employers, the Byzantine Empire, the Catalan Company had traversed the southern Balkans and arrived in southern Greece in 1309. The new Duke of Athens, Walter
of Brienne composed his testament there and led his army forth. The presence of the Frankish army at Zetouni at this time is a further testimony in favour of locating the battle at Halmyros, as Zetouni lies north of the Cephissus but southwest of Halmyros. For Muntaner's and Gregoras' accounts to be correct, the Catalans would have to be behind the Duke's army; Gregoras furthermore writes that the Catalans passed through the Thermopylae to arrive in Boeotia, which is extremely unlikely given the presence of strong Frankish garrisons at Zetouni and
