The setup for this scenario heavily favors the Brits. They heavily outnumber the Germans and have to cause step losses and control cities to get the victory points. The only question comes down to whether the Germans can damage the Brits and hold enough city hexes to win. The biggest advantage the Germans have is that they're hidden.

This advantage ceases to exist when playing solo. The Brits can never walk into a trap, and hence have little to fear when moving forward. The only problem the Brits had in this episode was to keep the formations together as they attacked. That said, the Germans were very spirited in their defense and getting them out of their holes was difficult.

I rated this a 3 because if the defense the Germans exhibited was coupled with surprise attacks from hidden units, the cohesion the Brits enjoyed would likely disappear. Jumble the British column and gaining victory conditions would improve dramatically.
