Campaign 1814 vs Napoleon at Bay

[Sir John Cope]

The JTS site gives this brief description: "La Patrie en Danger - this is the entire campaign from late January to the gates of Paris on March 30th."  Is this played on a map of the entire region of eastern region of France, Paris to Bar-le-Duc, Laon to Troyes? Or is played on a series of small battle area maps, the results of each battle carrying over to the next? 

I ask because, of the dozens of board wargames I have played over too many decades to mention, Kevin Zucker's design "Napoleon at Bay" (AH, then OSG) remains near the top of my list, so I'm wondering if 1814 covers (literally) the same ground.
