We probably played many games of Heroes 6, it's a very long and interesting game, I don't remember everything, but I was in a worse position in terms of control, and my opponent was in a worse position in terms of army and stats, plus the morale of the Valkyries destroyed them in the Fortress Battle. My opponent made a mistake, by the way.
Here's what the Fortress Battle looked like:
Valkyrie 42-34-23-200, good stats, but without tactics
9 Archers, 137 Marksmen, 27 Fanatics, 36 Ducks, 45 Royal Griffins, Ballista, 4 Angels, 15 Champions, Cloak of Resistance, and a bolt for 877
against Crag
13 Archers, 8 Gray Wolves, 51 Dogs, 37 Ducks, 5 Birds, 1 Bird, 1 Bird, 1 Bird
Ballista
Bolt for 575
My opponent rushed in because I positioned my units like a beginner. I don't think I would have lost even without the morale bonus, but with it, the Fortress Battle was hopeless for him. I lost 9 Fanatics, 9 Archers, 20 Ducks, and 4 Angels.
Thanks for the game.
