Danish Troop Ship to Bergen 1787 - 1789

I am not sure if anyone can help but I am trying to find the ship that my gggggreatgrandfather arrived in Norway from Denmark. He was a professional soldier belonging to a Hussar corp stationed in Bergen. He was discharged in 1789 and left Bergen for Moss to start a new life. He was German in the Danish Army serving in Norway. I have a ship name of Sjælland but I think that may have been a ship leaving Bergen for Denmark with returning soldiers. Any and all help or advice will be greatly appreciated.[:)]
