How were king Williams castles attacked in 1066?

In 1066, King William the Conqueror faced resistance in England, leading to the construction of several castles to establish control. These castles were often attacked through direct assaults, including siege tactics such as surrounding the fortifications, cutting off supplies, and using siege engines like trebuchets to breach walls. Additionally, some attackers attempted to undermine the walls or set fire to the wooden structures. Despite these efforts, many castles proved resilient, aiding William in consolidating his power in England.
