OK, here's a question.
Let's say both the Rooks and Bish are attacking a Knight field at the same time.
The Rooks get 8 troops in and 2 die.
Then immediately after the Bish show up and let out troops, also get 8 in and 2 die.
Did the Bish troops cancel out the rook troops?
Or are Rooks and Bish both just two troops from the capture if they get them there in time?
(i'm fairly certain that the Bish can't "use" the Rook troops and only put in two troops to get the capture, but to be honest i've not tried it, that's just a gut feeling)
