The result stands - English feudal Army creamed by a bunch of sub-human peasants (snigger, snigger).
The point of divergence here is that Wallace dies. Sir Andrew Moray doesn't.
So the incompetent blue-faced Australian cradle-snatching dog-robber isn't around to screw up later. Andrew Moray, being an experienced professional soldier rather than a cattle thief, doesn't get sucked into giving battle at Falkirk the next year.
What happens next?
