Loghain and Ostagar

What is your idea of Loghain's retreat from Ostagar? First it appeared to be a betrayal and I didn't really believe Loghain during the conclave when he said it was a strategic choice but in the "return to ostagar" mission, the king's guard who dies at the beginning tells you that even the King knew the battle was lost and therefore tried to hid the king's treasure.

So Loghain was not so wrong after all. Doesn't change that he did a lot of other bad stuff justifying the warden decision to kill him but maybe ostagar should not be one of them?
