The Sacking of Bergen in 1393 was one of two attacks on
Bergen by the
Victual Brothers, a former trading guild turned to
piracy. The second attack was many years later, in 1429. The Victual Brothers raided the town, pillaged and looted goods and killed the garrison and possibly also civilians. After they had taken control they proceeded to burn down the town before leaving with their booty.
