Is Konigsberg supposed to withstand this many breaches?

[Tac Error]

I'm playing the 57-64 campaign and at the stage where Russian forces have entered the war. I've been besieging Konigsberg for quite a while now and been inflicting breaches. Below is a screenshot of my latest turn. I've made 19(!) breaches so far but I've yet been allowed to carry out an assault. Is this supposed to be normal?

Try using an active general......

Thanks, I think that helped. Still, it's rare to see the number of breaches exceed what the siege icon shows--haven't seen that happen before in my playing experience.

Is there any additional benefit for more breaches than fort level other than "repair protection"?

As long as a fortress is a port, like Konigsberg, you have to take it with assault. It will not surrender as a landlocked fortress would do.
No benefit to additional breaches.

What I was saying, in taking a city you must choose the red assault posture. If you do not, you can have lots of breaches, but never take the city/fortress unless you starve it out, which you cannot do to a port. Get in red attack posture with all leaders who are active.
