No problem! I’m always fascinated by this. Germany actually built 360 of them in total, some of them being very successful (one sinking 3 (outdated) battleships in one hour).
Also, the set-up seems a bit off, France has 2 battleships while Germany only has one. The french had around 25 ‘battleships’ (dreadnoughts and pre-dreadnoughts mainly), while Germany had 48 of these ‘battleships’. Anyway, I’m looking forward to the subwarfare!
Munich is 2 territories away from Venice, so you wouldn’t be able to move in until Round 2. If you’re playing with the tournament rules, then that is allowed, and Germany would take control of the territory since they made the attack that killed the last defenders. You only have a choice when you have multiple defending powers that kill all the attacking units.
