Bastien and Marguerites third and fourth generations struggle through the final stages of imperial conflict between France and Great Britain in North America. William Pitt stalemates French military power in Europe by subsidizing Frederic the Greats forces on the continent and blockading French ports. This strategy prevents France from shipping reinforcements and provisions to its colonies, and clears the way for Englands powerful navy to project and concentrate British military forces against French overseas colonies in the Americas, the Caribbean, Africa, and India.
