May-June 1940 - the breakthrough of the Panzers - is the focus of this new battlefield guide by specialist historian, Jean-Yves Mary.

Supplementing the previous two volumes (Corridor des Panzers and Zur Kuste), this guide permits the reader to follow—crossing towns and villages, particularly Ardennes—the itinerary of the battles presented in the two volumes of Corridor des panzers.

Included are numerous photos comparing the sites as they were in 1940 to present day, along with colour maps.
