In our 4 player 3 AI PBEM game we have seen two instances where a major power transport fleet has been captured as a result of Naval Port combat, but the mechanics of the capture seemed a little strange.
As Russian, I attacked 6 Turkish LF and the 10 Turkish Transports in a garrisoned Athens (Guns=20) and after 2 turns had destroyed the 6 Turkish LF ships. But at the end of the second combat phase, with only the Transports left, they were not automatically captured. I then had to run the guns for a third turn, attack Athens, and then and only then did the transport fleet become captured - it disappeared off the map and a fleet building symbol appeared in Corfu. The next turn the building symbol became a little ship icon, and as soon as I dock my Russian transports in Corfu, I will have 20 transports at my disposal.
The British pulled a similar stunt on Toulon, capturing the 20 French Transports using the same sequence of events.
My question is if the transports have no value for combat, why are they not automatically captured when all enemy combat fleets are destroyed - why do you need that one extra combat vs the port guns before they become captured?
Has anyone else seen this sequence of events in their game?
