Please be very specific about how far you are moving.
Normal movement is 30' (or 25' for a dwarf)
You can attack or take some other action and move 30' in one round.
If you forego your attack and dash you can move 60' in a round.
One person hauling a dwarf can go 30' and take no other action besides hauling Dok. He is stable but still unconscious.
Two people can haul Dok 45' in a round.
Fleeing melee for Gerdar likely provokes an attack of opportunity. (Only from melee, not archers)
So please be cleari if you are moving 30' or 60'
Be clear about how many people are moving Dok.
Dashing across the river could lead to falling (dex check) but it isn't likely. (You know this as you have crossed here before.)
