The Lithuanian Chronicle blames him and Uliana of Tver, Jogaila's mother, for initiating the Treaty of Dovydiškės, which caused the Lithuanian Civil War (1381–1384). The Chronicle further stipulates that Vaidila held a personal grudge against Kęstutis, who did not recognize his new noble status. For his service in negotiating peace between Jogaila and the Order, Teutonic Knights gifted Vaidila some land on the Samogitian–Livonian border and perhaps two "hufen" (historical land unit in Germany) of land near Ragnit. When Kęstutis briefly took power during the civil war, Vaidila was hanged. Jogaila revenged his death by executing Vidimantas and his son Butrimas, relatives of Birutė, wife of Kęstutis. After Vaidila's death Maria was married off to David of Gorodets.
