First of all, when there is a major battle my army having sustained casualties, and I'm unable to achieve the objectives. I fought Austrians in a major battle just outside Vienna, defeated them but my army is now wasted and I cant take the city, so I had to go way back to French territories to replenish my army and then when I came back I saw Vienna again had a fresh full garrison. The cycle goes on and on. Now that would seem un-Napoleonic and very annoying.
And then there is a large garrison at Berlin and all Prussian allies declared war on me, I will have to take all the capital cities of German states and then to Berlin, that would seem like eternity considering such slow replenishment rates!!!
And I'm no bad strategist, I won every major battle but my army is incapable to take any city
Please give some advice, this is the only problem the warrior king is facing
