I had a hard time with this one too, but there's kind of a cheesy way to win. The map is pretty small in the beginning, and then opens up a little more for the final objectives (capture those two region). What you want to do is capture as many regions as possible early on. The first two objectives of that level, the map is smaller. After completing those objectives, the map gets bigger. Then, the French end up having 3 regions and infinite money to keep making full stacks. What you actually want to do is conquer everything inland and destroy all French troops. Then build up two full stacks across the river. These two stacks will be used to take the 2 French regions that are revealed later on. Finally, take the French region on the peninsula (nova scotia?) with the smallest army possible. This completes the next objective, and the map gets bigger. You have two full stacks ready to take out the 2 French regions that appear. Keep your two stacks together for the extra reinforcements. There's a fort you have to capture and the two regions, all of which have full stacks guarding them.
