Game 28881 (Darklords34)
Maybe this changed and I am not aware of it but I had 5 boats sitting on a bridge. 4 of which were Galleons and one was a Barge (or whatever the crappiest boat is).
The units were 3 Pikemen and 2 Lt Calv. Prior to the battle ALL showed getting a combat bonus for being in the open. I was attacked by my opponent and in the battle screen all fought at 15 strength and I got reamed when I should have done a LOT more damage. And no, there were no Unicorns involved.
I suspect the game saw 1 army in a Barge and put them all in a Barge for combat purposes.
