Here’s the response I made to your posting in the Pacific forum.
AA 1940, Pacific: 1. If an US amphib assault of destroyer and 2 loaded transports hit the Carolina Islands, and the defender scrambles 3 fighters and kills the destroyer, can the transports retreat to a friendly adjacent sea zone (I know can’t unload) or are they killed?
The surviving transports can retreat to a non-hostile sea zone through which one of them travelled, but only after all the hits from the defenders are assessed. If the scrambled fighters got more than one hit in the situation you described, each hit beyond the first is assigned to one of the transports. Any units on a transport that is hit are lost.
The transports can retreat but cannot unload. In this case, on the next Japanese turn the transport is probably dead unless there are Allied ships guarding the transport.
If a US transport picks up 2 ANZAC infantry, can they goto an enemy island during non-combat phase? There are no enemy ships there but could scramble enemy fighters. During the ANZAC turn, they send in ANZAC combat ships and planes to support the landing of their troops from the US transports. Ok?
When loading Allied troops on a US transport, the transport cannot move until the US turn and the troops cannot be unloaded until the Allied power’s turn comes back around. The sequence you described is:
ANZAC: Load troops onto a US transport during ANZAC non-combat movement.
US: Move transport:
ANZAC: Unload troops during either combat or non-combat movement. (Note that in this case the transport cannot retreat as it did not move.)
Hope this helps!
