The soldiers built abatises to block the enemy's advance.
During the siege, the defenders constructed several abatises around the outer perimeter to slow the approaching cavalry.
The strategic placement of abatises forced the invading army to divert from their main route, significantly delaying their arrival at the capital and allowing the city's garrison to prepare for a prolonged defense.
