The army pushes on quickly giving the retreating army no chance to regroup and  making it disintegrate under the pressure of the pursuing army.

Your army eventually reaches the two interlocking cities of Mtol Daerine and Avat, but soon after, the general at the head of the army requests that in order to successfully besiege the two cities, he needs about 20.000 more soldiers to fully encircle them as the cities are too fortified for his current army.

He also asks in a more private letter to send your secret weapon to tear down the walls of the city. It could also serve as a intimidation weapon to force the enemy cities surrender.
