The Holy See's attack on the south city lasted for an entire day. By the time evening came, both sides had already suffered heavy losses. Usually, the defending side would have the advantage, even if they had poorer soldiers because a twenty yard tall city wall was an obstacle that would be difficult for any army to overcome.
The soldiers of the Holy See were always able to continue fighting unless their limbs had been cut off or a huge hole had been blown open in their stomachs.
The alarm had already been sounded since morning and the reply they received was to hold the city and wait for reinforcements.
