Hours after the ambush in the Maritime City began, the actions planned earlier by Minos and his soldiers were finally being put into practice!
Even before the conflict in that city began, Angela had sent crows with letters that basically said that the attack on that place would have begun by the time they were received.
And since those letters had been sent to the secret army bases in Yellow City, City of Waters, and the headquarters, the soldiers and allies in those places had quickly prepared themselves to make the subsequent attacks.
The plan of the Black Plain Army was to deal with the leaders of the enemy groups in the vicinity of those two cities as soon as they received notification of the start of the conflict in that city.
