As you can see there were Union troops on board.
There was a Union force in Wilmington NC, but because of developments elsewhere I thought there was a good chance they would be reinforced so I moved my fleet to intercept. However, those units were not reinforcements, they were the force that started the turn in Wilmington!
Curiously there were no transports in Wilmington at the beginning of the turn, so you might ask as I did; how did they get on board. Apparently ground units can target a naval transport and thus board it in a coastal region without the inconvenience of waiting for them to enter the port and dock! I had no idea that 19C era men, horses, canons and wagons were capable of walking on water. Imagine that! Crazy but true, I tested it.
But I'm not done yet. You might be wondering what happened to those 5000+ Union soldiers listed as taking part in the battle? Apparently nothing much. Although I captured all the Union transports there were no soldiers or equipment anywhere on them. That whole Union force seems to have cleverly used the ruse of surrendering the transports to walk on water unnoticed to Onslow NC. A 100% MC region for the CSA a condition which should preclude a retreating force from going there.
Anyway, I feel cheated here. Those Union troops should be captured or be severely decimated by the combat, but they look totally unscathed.

And Longshanks, can you ban this boarding of transports at sea? Its gamey to the point of being an exploit.
Arrgh, my screenshot doesn't post.
Got it now
