Basically, what this is depicting is a naval blockade, even if we don't win, we'll try making sure the siege has no reinforcements and we can set up catapults on our ships. Then, our next goal is send fortifications and draw the enemies a little further from the city for a battle. Then, as a distraction, we'll cross the river and then go for an encirclement or trap them in the mountains, in which we are experts in. Also, we'll send some troops at the green area to make sure they don't cut off our siege.
