Summer war in Läänemaa and Hiiumaa
Battles broke out in the summer of 1533. Wilhelm's men raided Hiiuma, which Buxhoeveden answered by sending his troops to pillage Läänemaa.
Among other things, vassal fort in Virtsu (Schloss Werder) was burned to the ground, and a bit later, Old-Pärnu and Audru suffered the same fate. Wilhelm began to send complaint letters, talking about his mistreatment and accusing Buxhoeveden of numerous crimes.
It is obvious that Wilhelm suffered in the war more than the Order, but it seems that he had been the one to initiate pillaging. A truce was signed in autumn, but as all tries to mediate peace failed, it was decided to discuss the matter in the Livonian Diet.
