@wittmann:
1. Yes.
2. Yes. Each scrambling Fighter would get one roll of 4 to hit and sink one TT, with its cargo onboard. On the next turn the attacker could retreat any surviving Transports. (Or stay and try an be sunk again, naturally,)
3. A Sub is ignored, unless a Scramble happens, then it is in the fight.
You did realise, however, that a Sub forbids an amphibious assault, if the Transport(s) is not escorted?Where is that rule in the book? I heared from it but in my game this weekend i could not find it.
Thought that transports can only ignore subs if they got a warship sailing with them.
See the rulebook:
@rulebook:
Transports
….
However, a transport is not allowed to offload land units for an amphibious assault in a sea zone containing 1 or more ignored enemy submarines unless at least 1 warship belonging to the attacking power is also present in the sea zone at the end of the Combat Move phase.
So the requirement of an escorting warship applies to the ability to unload troops (not to ignore a submarine).
HTH :-)
