Every battle fought in World War II was part of a campaign — even as each battle was being fought, the generals were planning the next one. The conclusion of every successful campaign affected the course of the war as a whole. By participating in a campaign, you can make a valuable contribution to your side's war effort.
Campaigning adds a whole new dimension to your Flames of War battles. Individual battles become part of an unfolding story as your fortune fluctuates between victories and defeats. Instead of just a single victory, can you string together a series of victories and prove your superior generalship? Or perhaps, as you get the measure of your opponent's force, you can turn early defeats into a triumphant reversal in a later battle.
