Canquigny is a very small scenario that plays very quickly. You can play it several times in one sitting. That's about it for its good points.

Even if the Germans draw poorly in picking their strongpoints and the Americans get their reinforcement early, the Americans have less force than the Germans in this scenario. The Germans can also reach the scenario objective (in a town hex) first. This forces the Americans into a poor choice -- hold back and accept the draw, or attack and hope for extremely good luck to give them the win. If luck isn't with them, they are almost certain to lose if they attack.

This one's very historical, but not very balanced. I can see why this one was not included in the two newer editions of Airborne.
