you can defend it. For beginners like me, set the difficulty to the easiest and then start to make it more difficult if you think that you are ready for a harder battle. You can set your battle sizer to 25 [lowest] in the options. I used easy difficulty last night coz i defended Wercheg on my own against 8-10 khanate lords, they love me. I had 120+ troops [majority are swadian knights , vaegir knights and mercenary cavalry, few hired blades, archers] kagainst 500+ they had like 3-5 attempts to siege me and I was lucky to survive, I was about to run out of funds because I cant get my ass out of the town, I cant make money, I was so close on having a huge debt, I was thankful they stopped the siege when I was about to run out of denars. Also they are a lot better archer than me, i was trying to kill some while they are stuck in the ladder and some arrows push me back almost every time so I decided to just go in the ladder, and break some skull. Ill back this up with my screenshots that I will upload later when i got home.
