In 489, Thraustila, King of the Gepids, tried to hinder the Ostrogoths from crossing the river Vuka during Theoderic the Great's campaign against Italy, but the Ostrogoths routed Thraustila's army. The Gepids also lost Sirmium to the Ostrogoths, according to Walter Pohl. In short, according to Walter Goffart, Thraustila's son, Thrasaric, "regained control of Sirmium but possibly under Ostrogothic underlordship". Theoderic the Great dispatched one "comes" Pitzia to launch a campaign against the Gepids who either tried to capture Sirmium or wanted to get rid of Theoderic's suzerainty in 504. Comes Pitzia expelled the Gepid troops from Sirmium without much resistance.
