Little Gun that Led the Blitzkrieg : The Rise of the German 3.7cm Anti-Tank Gun

Long overshadowed by the famous armoured vehicles of the Second World War, the Kfz. 13 and Kfz. 14 were nonetheless the machines that laid the foundations of German armoured reconnaissance. Emerging in the aftermath of the First World War—at a time when Germany was forbidden to build tanks or modern AFVs—these light scout cars became an indispensable testbed for new tactics, new technologies, and a new generation of soldiers.Though lightly armed, thinly armoured, and limited off-road, the “Bathtubs,” as they were nicknamed, played a crucial role in rebuilding German mobile warfare from the ground up. They allowed reconnaissance units to train under realistic conditions, helped shape early mechanised doctrine, and gave German industry invaluable practical experience in designing future armoured fighting vehicles.By 1939 the Kfz. 13/14 were obsolete, yet their influence could be felt at every level of the rapidly expanding Wehrmacht. The crews who trained in them would later spearhead the lightning campaigns across Poland, the Low Countries, and France, applying lessons first learned behind the wheel of these modest scout cars.This book offers the first comprehensive history of the Kfz. 13/14, combining technical analysis, operational context, and rare imagery to illuminate a little-known but highly significant chapter in the evolution of German armoured warfare.
