Had to send my latest save file to Legend of Total War. All Gutter Runner stack with 3 engineers for extra ammo and speed, got caught underground by 4 dwarf armies. If I flee I get hit by 4 different armies one led by Belegar, one led by Thorgrim and one led by Thorek. It's a bit more than my single army can take but the underground battle has no room to move.

He asked for more disaster battles and got hundreds two months ago so it's unlikely he'll get to mine but I can always hope.
