Marathon, Hastings, Midway -- just a few of the major battles covered in this series, which introduces readers to the wartime engagements that changed the course of human history. Each book gives a historical account of a decisive battle -- its participants, the political climate leading to the engagement, and the deciding factors that ultimately led to a victory or defeat. These two separate military engagements in 1777, in which the Americans triumphed over Burgoyne, are considered a turning point in the Revolutionary War.
