And surviving Italians are repaired in the same round. I have no idea why this would be a good strategy. Having my AH fleet bolstered by a sub every turn makes it so that others can’t move their navies away and when the French or whoever move their fleet away i immediatly attack the fleet that remains. And by the time Rome is conquered then the mines are gone and by that time my five subs can wreak havoc on all ships with no minefield to stop them after their first move out of the Adriatic.
