Subjective: The following part of this article is subjective to the editor's writing. Therefore, it may not work for everyone.
The first thing you will want to do in this chapter is rush everyone to the west to help protect the mansion. There will be four new units immediately under your command already protecting it, but they are very weak and cannot last long. If you intend to keep all of them alive, you will likely want to leave one guarding the mansion itself and place the others on mountain and forest tiles in front of it. The enemies are not particularly powerful or accurate so the avoid bonus will hopefully keep them alive until your units arrive. You can also send Karin, possibly while carrying another unit, over to provide quicker support. Bring Safy and a Physic Stave if you are particularly invested in keeping the Njörun Knights alive.
The only enemies to fear on the map are the Dragon Knights. If you are interested in keeping all of the new units alive, you will probably want to engage them with your current stronger ones. Their Killer Lances can be very problematic, but your units will be surrounded by trees and mountains to lower their chances of hitting. Use wind magic and bows wherever you can to take them out easier. Once your units make it to the mansion, you should have little trouble finishing off the remains of the attacking army.
After them, you can take the rest of the chapter at your leisure. There is a Meteor using Bishop on the right side surrounded by Armor Knights, but you can exhaust his tome relatively safely by using the mountain tiles. After that you can capture him for his Wind tome and Physic staff, kill off the armor knights. Once all the threats are cleared you can use the arena and shops as you see fit, make sure to get Carrion to talk to Selfina to get your Elite Sword, then move on to the next chapter.
It would also be wise to check the vendor if you have additional funds and purchase a Stamina Drink, which will be useful if a unit you plan on using is too fatigued to be deployed. You can only purchase these from vendors in Chapter 9 and Chapter 14.
