The defeat and death of Ferdinand ensured the continued Angevin supremacy over Achaea and checked the further movement of his allies, the Catalan Company then occupying the Duchy of Athens.
The Angevins, as part of a complex marital pact and transfer of rights, arranged the marriage of Isabella's eldest daughter, Matilda of Hainaut, to Louis of Burgundy in 1313, and invested the couple with the Principality.
In the meantime, Louis' wife, Matilda of Hainaut, travelled directly to the Principality, whereupon she was greeted by a number of local lords, including John I Orsini, the count of Cephalonia, and Nicholas of Dramelay, the baron of Chalandritsa, who repudiated their earlier oaths to Ferdinand and declared for her.
[4] After an unsuccessful attempt to capture the castle of Chalandritsa from Ferdinand, Louis moved to Patras, where his troops were reinforced by Byzantine forces sent by the governor of Mistra, Michael Kantakouzenos.
[citation needed] For his own part, Ferdinand expected reinforcements from the Catalans in the Duchy of Athens and from Majorca, but rather than retreat to Glarentza to await their arrival, he determined to give battle.
