Binger Kurverein (Alliance of Bingen) by the Empire's Kurfürsten against Sigmund, who could not afford to fight three wars at once: the planned one against Friedrich, the brewing one against the Kurverein and the ongoing one against the Hussites. On February 17, 1425, King and Count made peace at Castle Hornstein; Oswald was present. Oswald returned to Tyrol to find himself completely penniless. Count Friedrich insisted on the payment of the 6,000 ducat surety. Oswald tried in vain to get hold of the money and fled Tyrol. In 1425 he resided in Castle Neuhaus near Gais, which at this point was not yet part of the County of Tyrol, but part of the County of Görz. Friedrich immediately used the peace with King Sigismund to renew the siege of Castle Greifenstein. After Wilhelm von Starkenberg's capitulation on November 26, 1426, Oswald was the last nobleman feuding with Count Friedrich, and was summoned to the Landtag in Bolzano. Oswald again fled Tyrol, but his flight was discovered. He was apprehended near Wasserburg on Lake Constance, brought back to Tyrol, and imprisoned in Castle Vellenberg (later Castle Sonnenburg) in Innsbruck. Oswald now had no choice but to make peace with Count Friedrich, who forced him to pay Martin Jäger a compensation in exchange for the stolen tithes, and in the process allowed Oswald to acquire full ownership of Castle Hauenstein and its estates. Furthermore, Oswald had to swear to refrain from any contact with nobles from outside Tyrol unless sanctioned by Count Friedrich. In 1428, Oswald broke his oath and traveled to Heidelberg to meet Kurfürst Ludwig von der Pfalz, Archbishop of Cologne, Count Dietrich II von Moers and Duke Adolf VII von Jülich, with the aim to garner the help of the League of the Holy Court in a dispute with his cousin Hans von Villanders, who owed Oswald 2,200 ducats. While there, Oswald entered into a fray between the Domkapitel of Brixen and the new Prince-Bishop of Brixen, Ulrich Putsch (died 1437), who was a friend of Martin Jäger, a confidante of Count Friedrich, and soon-to-be bishop chancellor of the County of Tyrol. The clash culminated in a coup on October 30, 1429, supported by Friedrich and led by Oswald against the bishop, who while being a prisoner of Oswald was beaten publicly by him. Initially, King Sigismund backed Oswald, but when informed by the other side in the dispute,
