both Sigismund and Friedrich switched sides and reinstated bishop Ulrich. In 1430 King Sigismund summoned the nobles of the Holy Roman Empire to a Reichstag in the city of Nuremberg and Oswald with his brother Michael immediately left Tyrol to meet the King, who instead of going directly to Nuremberg undertook a two-month detour to the South German cities of Überlingen and Constance to celebrate Christmas. During this period, Oswald wrote many songs of an erotic nature, the most famous being "Ain Graserin" (KL 76) about a bathing maid, whose "frizzy hair" between her legs leads a man to have sex with her on the spot. In Nuremberg, Oswald became a member of the first rank of the Order of the Dragon, a rank King Sigismund awarded only to two dozen nobles. Along with the honor came the obligation to participate in Sigismund's disastrous expedition against the Hussites in Bohemia in 1431. Oswald experienced firsthand the mass flight of the 130,000-strong Imperial army on August 14, 1431, when the entire army panicked after sighting the 50,000-strong Hussite army approaching and singing. Sigismund sent Oswald back to Tyrol to prepare the county for an expected Hussite invasion of the Empire and invited the Hussites to the Council of Basel to negotiate. Sigismund himself fled to Milan and later to Piacenza under the pretext that he had to go to Rome to be crowned emperor. During this time Oswald commissioned the Neustift Monastery to create a second manuscript collection of his songs. Sigismund called him to join him in Piacenza and Oswald obliged. The unpleasantness of his visit inspired him to write the complaint-song "Wer die ougen vil verschüren", which he set to a French melody. In May of the same year, Oswald was sent by Sigismund to Basel. After over a year of negotiations, Sigismund was crowned Holy Roman Emperor on May 31, 1433, by Pope Eugenius IV, with Oswald probably in attendance. During the next years, Oswald's life settled down, and almost no reports of fights, brawls or trials are preserved. This changed with the death of Count Friedrich on June 24, 1439. As the heir Sigismund was only twelve years old at the time, a guardian had to be found until Sigismund came of age. The Landstände of Tyrol choose Sigismund's uncle Friedrich V, Duke of Austria. The contracts of the guardianship were put in Oswald's care. Oswald used
