Guide Request: Meiji Restoration 2 - Japan-Qing War

Try not not to split Your team. 
I used two artillerists here - mostly all the campaign in Industrial require 2 artillerists - to bombard the wall in the upper corner.
Do not remember ... but if I  remember correctly strongest generals supported them (Nobunaga was definetely there also),  while couple where... just waiting - not getting under the bombardment of the walls artillery.

After my artillerist made a breach in the walls I entered to clear it and put  one healing princess (in the Archery - in order to fight against the tower without retaliation and to be healed at the same time). I put Nobunaga as he was severely damaged. At that time I started to spam artillery in the factory to destroy the fort while most of the team started to advance through the walls on the continent (on the way to infantry building - not to archery). As soon as You are inside - try to hold for a while in the infantry building as You will need to eliminate the wave coming from the second fort. It is important that Your artillerist are focused on the gates on the way to the fort after they are near the barracks. As soon as it is done I was spliting my team. One Artillerist (with support of course) went to destroy second fort. Another one was destroying the gates to open the path to the red-marked Archery (last objective of the mission).


Red-marked factory. I occupied it and and left the possition. But You need to build at least 1 unit here. Maybe 2 will be necessary. It is important to block the gates. As there is a unit (artillery or archer - do not remember) who will try to take the factory back with support of the towers. So You will need to spam 1 or 2 units as I said to survive there while Your forces are busy with second fort and red-marked archery.

I spent 4-5 attempts to be in time to make it 3 star. It was not an easy mission as You need to advance 3 directions at some point (second fort, red-marked factory and walls on the way to the red-marked archery). Try to avoid fighting with the enemies on the way to the last red-marked archery - focus on killing the unit unside the archery and occupying it same turn. If You will leave him with low HP - AI will leave the archery and spam new unit there.
