Ahoy, propbeanie...

Am on patrol 3, same boat, Sargo class, sailed out from Surabaya, right before the shake up with sub command (SowWestPac, falling under ComSubsSowWesPac iirc that message, exactly..

) right after that, got message stating that Surabaya had been abandoned. Before sailing, got orders to go to area E3 & await further orders.
On arrival in the area (close enough to trigger a flash radio traffic message, that is...) got orders to sink enemy targets & on having full autonomy in order to accomplish said task.
Ok, now that this info is out of the way & disclosed... My query is this...
With said orders, do I have to stay in that general area, to sink a ship (preferably big enough to trigger the completion bell on it, that is...

) & complete that objective.? Or, can you motivate to any other areas to complete said task objective..?
Inquiring minds, wanna know.
