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.
