 As the war raged between Princemarch and the Desert to the south, Walvis commanded the northern army and the besieged city.As his troops were disheartened by the lack of action, Walvis launched some small attacks, trying to pull the "Merida" into action Eventually the trade supplies from Cunaxa to the "Merida" were cut off by Dorval's ships, just as those ships also supplied Tiglath.The Desert troops regained their spirits, and the "Merida" had no choice but to attack the city en masse.
