The German lightning campaigns against Poland in 1939 and the western Allies in 1940 brought the term blitzkrieg into the popular vocabulary and changed the face of warfare forever. This book presents ten exciting and balanced historical battles for Command Decision from both the 1939 Polish Campaign and the 1940 French Campaign, complete with historical summaries, detailed maps, and carefully-researched orders of battle. Also included is an overview history of the campaign, complete data charts for the scenarios, and a mini-campaign stringing together three of the scenarios covering the bitter fighting in the Abbeville Salient in late May, 1940.
