Battle for Normandy Expansion

So I’m new to Vassal. Just decided to start some gaming again.

In the Module Battle for Normandy - Will buying the Expansion (which appears to be available at GMT) give me the required charts to legitimately play the whole campaign?

I don’t want to cheat GMT (at all) but the basic game is unavailable to get the required charts.

PS, If they ever re-print that puppy I’ll buy it in a heartbeat!
