While Berengar had begun to march his armies into the Prince-Bishopric of Trent, Duke Wilmar was engaged with the enemy Bavarians at Munich, his siege was lasting longer than he had anticipated, but it was going smooth enough.
The main Bavarian armies were up in the north fighting against the regions under von Luxembourg's influence. For Eastern Germany, they were fighting among themselves for petty reasons. There was not a single region of Germany that was not embroiled in some form of warfare at the moment; only small towns could escape the wrath of passing armies if they were lucky; most weren't.
Duke Wilmar was reading a report about Berengar's recent activities. In under two months, he had subjugated the Northern and Southern regions of Tyrol and had marched on Trent with the intent of annexing the territory through the right of conquest. Berengar's actions greatly enraged the Church, who had demanded Duke Wilmar do something about his lowly vassal.
