Necropolis – “Misfortune never comes alone” [Campaign 2 – Mission 1]

Guys, good evening everyone. I have a question (maybe I was just too lazy to read 9+ pages), I don't understand where the passage to Castlerose is. I'm replaying the campaign with another player and can't find the way to the yellow ally... maybe I missed something. Please send a screenshot if possible. There is this path blocked by a log, but it doesn't disappear((((
