The two rulers concluded a treaty of alliance, by which John de la Roche's brother and heir, William, would marry John Doukas's daughter Helen and receive the fortresses of Gravia, Siderokastron, Gardiki and Lamia as her dowry.
After the disastrous Battle of Ankara in 1402 however, the weakened Ottomans were forced to return the eastern half of Thessaly to Byzantine rule, while the remainder reverted to virtual independence, and the two forts of Pteleos and Gardiki came under Venetian control.
William reversed the territorial losses of his brother's reign, extending his control over Lamia and Gardiki.
