I might imagine British transports sneak through neutral Scandinavian countries and mine fields to the Baltic but I can't hardly see how that could happen through an active enemy occupied Dardanelles canal.
It can't. Naval units cannot move through the Dardanelles if Gallipoli and Constantinople are enemy controlled. But since transfer orders are given a turn ahead of resolution the program assumes you know what you're doing and that you've taken measures to ensure the transfer succeeds before resolution.
