[Trevally.]

If your base is at Wilhelmshaven you should be able to dock there.
You can dock at your base anytime. You do not need to do every thing in your mission to dock. After docking you can continue your main mission.
Remember your main mission is to fill the crosses in the info bar top left on your map view.

The re-deploy part is you current orders, but as I say tou dont need to do this. You can look on map for an orange diamond (patrol area).

There are buttons on your display (right side, near top). One of those will shoe you your old messages.
