Thats why they call those snake paths.

Anytime you siege you want atleast 3 times the number of the enemy. Second you want mutiple Breaches. without them you will loose more men and the enemy can bottleneck you.

I found it you have a mod or fix the hardy heat bugs and then played as they would back then in tactics you will do well. If you play like an RTS and just build and rush you will lose men and possible get AI path issue which will result in maybe you losing a possible overwelming win.
