I do not know to post video here or picture ( more like it is a bit complicated to do it, just let me drop it xD )
At Praven you can go from left side all way and get into the town there is nothing behind that wall so just go forward in town till you find a place to jump out behind enemy lines and take them out with arrows.
I think in Ahmerrad there is a door to be destroyed at left side as well but only you can pass so yea can kill them with arrows (more safe than jump in I play at highest possible difficult ).
Knudarr Castle gate is opened so just go trough there.
And at some Towns/Castless you can just bypass enemy and go for archers to steal their arrows and shoot at the rest to help your men climb in to the town, but you must go 1st since they wont react to you and place your units below the walls so they keep their shields at them...
