Scenario:
-Player 1 declares an 8 strength military challenge.
-Player 2 defends with 3 strength, but before the challenge resolves kneels two Stark characters and plays Lethal Counterattack ( http://www.cardgamedb.com/index.php/GoTCards.html/_/core-set/lethal-counterattack-core ).
With player 1's characters now dead (assuming no saves were used), is the strength of the challenge considered to be reduced to 0, so player 2 successfully defended the challenge, or with the attacking characters all gone, does no one win the challenge?
