The Invasion of Trent was swift and sudden; the three-prong assault on Trent, Riva, and Pergine Valsugana caught the Prince-Bishop completely off guard. Berengar gave no warning when he invaded Trent; as far as he was concerned, he was already at war with the region when they decided to supply his enemies. Due to the lack of notice, the Prince Bishop did not have time to raise an army in defense, not even the ability to form levies.
As such, he was currently surrounded in the City of Trent by Berengar's armies; as for the other key areas of assault, they could hardly even be considered cities; if anything, they were towns with a single castle. Both Eckhard and Arnulf would be able to take their regions and march on the final area with a significant population before Beregnar had even completed his siege of Trent.
