Ulrich was present on all the battlefields of Central and Eastern Europe. In 1354 he accompanied Emperor Charles IV to Rome. Ulrich and his troops fought side on the battlefields of Dalmatia, Serbia and Bulgaria. In Tyrol he fought shoulder to shoulder with the Wittelsbach family.

Soon his military operations led him far to the north, where he fought against the pagan Prussians. In 1355, he was back on the side of Louis I of Hungary in the fight against Venice and in 1359 he participated in the campaign against Serbia.
