Here, for the first time in English, is an illuminating German perspective on the decisive blitzkrieg campaign. The account, written by the German historian Karl-Heinz Frieser and edited by American historian John T. Greenwood, provides the definitive explanation for Germany’s startling success and the equally surprising military collapse of France and Britain on the European continent in 1940. In a little over a month, Germany defeated the Allies in battle, a task that had not been achieved in four years of brutal fighting during World War I. First published in 1995 as the official German history of the 1940 campaign, this book goes beyond standard explanations to show that the German victory was not inevitable and that French defeat was not preordained. Contrary to most accounts of the campaign, Frieser’s illustrates that the military systems of both Germany and France were solid and that their campaign plans were sound. The key to victory or defeat, Frieser argues, was the execution of operational plans—both preplanned and ad hoc—amid the eternal Clausewitzian combat factors of friction and the fog of war. He shows why, on the eve of the campaign, the British and French leaders had good cause to be confident and why many German generals were understandably concerned that disaster was looming for them. This study explodes many of the myths concerning German blitzkrieg warfare and the planning for the 1940 campaign. Frieser’s groundbreaking interpretation of the topic has been the subject of discussion since the German edition first appeared.

A “masterly account” of the juggernaut offensive that conquered France—but also marked the beginning of the end for Nazi Germany in World War II (Kirkus Reviews). In the spring of 1940, the German forces launched an attack on France that combined superb intelligence, cutting edge strategy, and new technology—the blitzkrieg, or “lightning war.” In just six weeks, it would achieve what their fathers had failed to do in all four years of the First World War. It was a stunning victory. But here, leading British military historian and academic Lloyd Clark argues that much of our understanding of this victory is based on myth. Far from being a foregone conclusion, Hitler’s plan could easily have failed had the Allies been even slightly less inept or the Germans less fortunate. The Germans recognized that success depended not only on surprise, but also avoiding a protracted struggle for which they were not prepared—making defeat a very real possibility. Their surprise victory proved the apex of their achievement; far from being undefeatable, Clark argues, the Battle of France revealed Germany and its armed forces to be highly vulnerable. And Hitler dismissed this fact as he planned his next move—and greatest blunder: the invasion of the Soviet Union. In this eye-opening reassessment, complete with maps and illustrations, Clark “presents a well-balanced narrative that highlights the knife-edge victory of the German forces” and reveals how very close the Nazi war machine came to catastrophe in the early days of World War II (New York Journal of Books).

The objective of this study is to determine if the German “blitzkrieg” and Fall Gelb of 1940 were an expression of operational art. Despite the mythology surrounding Fall Gelb, the campaign does not constitute a major breakthrough in operational art by the Germans. Fall Gelb was not an expression of operational art. This conclusion is based upon an analysis using the approaches posed by U.S. Army and joint doctrine, Dr. James Schneider and Dr. Shimon Naveh. The purpose of this study is to examine more closely what is meant by “operational art” and to use those contemporary insights to re-examine German military operations in France in May 1940, Fall Gelb. Fall Gelb was chosen because it is a campaign that is frequently studied and often used and abused to illustrate various points relating to military operations. The study of the Fall Gelb campaign offers a glimpse of past operations through the lens of contemporary thought. That study provides the contemporary military professional an opportunity to improve his understanding of operational art through the study of a historical campaign.
