Spring
We start building a Large Castle in Shinano, a Famous Tea House in Kai and improved farmland(+20% production) in Musashi. We also attack Suruga from Kai, and get a freebie as the enemy retreats.
Summer
We drop taxes to "low" and attack Totomi, Mikawa and Echigo. All attacks are called off all attacks due to heavier than expected enemy forces present at all provinces.
Autumn
We attack Totomi with a major force and Mikawa with a smaller one as a feint.
Attack on Totomi
Totomi is real tabletop terrain with not much in the way of anything, so my CA should have a good day.
As expected the YS don't even get to the action before it's over and the enemy routed. Quite heavy casualties in two of the CA units, but other than that a good result.
Winter
We start building a Famous Spear Dojo(produces YS +1 honor) in Aki, a Ninja House in Kai, an Archery Dojo in Hitachi and Superior Farmland(+40% prod) in Mutsu. Kai will be our main production province for "special units", ie. ninjas, shinobis, geishas etc. Hitachi will focus on archers and later arquibisiers, Shinano on Cavalry and Aki on infantry.
Attack on Mikawa
Another river province, and this time the enemy sets up so close that I don't dare to try and rush cavalry over. Instead I rush over a few YS who try to hold the bridge open
They take heavy casualties but manage to buy enough time for the cavalry to get over and start working on the enemy's flanks. In short order they corner the enemy daimyo and kill him.
A costly but necessary victory. Now I've got an easily defendable river province on my side of the border.
Meanwhile there's extremely worrying news from Totomi: The enemy is trying to break out of my siege!
