Toughest Scenario?

As far as I recall, the only scenario that I never won was Pskov as a stand-alone scenario (it's easy to hold all 3 towns but that always rates a loss and I only have been able to take a few German towns before time elapses; in campaign mode, Pskov has easier victory conditions), so if you won it please let me know what you did.
