Can a transport establish a retreat route?
For example:
Say Italy has a destroyer in Z92.
UK controls Gibraltar and has a submarine in Z94. Â UK player wants to get the submarine to Z91 to prevent the Italians from sinking the submarine next turn.
Can the UK send an empty transport to Z92 from Z91 along with the submarine from Z94 to Z92, attack one round, and if the attacking submarine misses, retreat both the submarine and the transport to Z91?
If not, what if the UK sends a loaded transport through the strait to amphibiously assualt Morocco or Algeria from Z92 along with the submarine, goes one round and retreats (land units staying loaded on the transport in Z91)?
Again - can a transport joining an attack at sea establish a retreat route by itself like all other ships can? Â Even if empty, or if there is no amphibious assault?
The rules appear to be silent on this issue, which makes me think it’s allowed. But as long as a transport can enter a naval battle in a combat move with no intent to amphibiously assault, I would guess the answers to my questions are both yes.
