The Globe At War
This Month in History: February 1940
February 17, 1940:

On October 9, 1939 Hitler issued Directive No. 6; a document, that among other
things, advanced German plans to attack France later that same fall. Given the code
name "
Fall Gelb - Case Yellow" the plan Hitler's General Staff had prepared for invading
France unimaginatively involved a virtual repetition of the World War One attack into
Belgium; an attack to the west into Belgium in the first stage followed by a move to
the southwest into France's interior in the second stage. Nonetheless, leading officers
in the German General Staff managed to get Hitler to hold off on his plans to attack
during the fall of 1939; ostensibly because the German army was worn out after the
Polish campaign and needed the time to refit before moving against France. The
German army high command (OKH) was pleased over wining the sought after delay in
offensive operations, however disaster seemingly struck early in the winter of
1939-1940. On January 10, 1940 bad weather forced down behind Allied lines a
particularly important German aircraft. The Allies reaped a substantial intelligence coup
when an examination of the plane's contents revealed a German officer travelling in the
plane had been carrying enough information to give away the German invasion plan's
focus.

It was this mistake that opened the door to a far more creative and explosive plan.
General Erich von Manstein, a man most military historians regard as the best German
commander of the Second World War if not the best operational level commander
produced by any army during the War, and a man justifiably convicted as a war
criminal following the War, had authored and proposed a different plan over three
months earlier. Nevertheless, Manstein's plan had never gotten past OKH's top
echelon; notably Brauchitsch and Halder; both of whom had played the pivotal roles in
rejecting Manstein's plan. With the intelligence breach of January 10, 1940 however
OKH had no choice but to look at other options. Consequently, in February 1940 the
German army war-gamed Manstein's plan.

In contrast to the original plans for Case Yellow Manstein's plan coupled simplicity with
deception and concentrated strength. Manstein's plan featured a high operational
tempo; strong combined arms German armies would attack into the Netherlands and
draw allied forces to meet what appeared as the German army's main attack axis. At
the same time the primary strike force, including the strongest armored concentrations,
would attack through the thinly defended Ardennes and penetrate deep behind the
Allied forces advancing into Northern Belgium and the Netherlands. Upon breaking out
of the Ardennes
the German armor would turn, but not southwest into France as the
allies anticipated. Instead, the German armor would turn northwest, driving to the
English Channel, and trapping the Belgian army, Dutch army, the BEF, and France's
best armies in one huge pocket. In seeking to strike a decisive blow Manstein's plan
met the essential elements underlying German army doctrine since its Prussian
antecedents.

In spite of the strength of his plan, Manstein still needed a break if he were to have a
proper hearing on the merits of his plan. Manstein got his break when Henning von
Tresckow, one of Manstein's former students at the General Staff, and one of the
leading organizers of the wartime military resistance to Hitler's rule, turned out to be
friends with General Schmundt, Hitler's Wermacht ADC. From these connections,
Manstein found his most powerful supporter. Hitler reviewed Manstein's work and
instantly took to the plan; given its daring and audacious nature as well as the fact if
successful it could deliver results in the shortest possible time. As a result, on February
17, 1940 Hitler approved Manstein's plan, issued new Army Operational Orders, and
consequently changed the course of history.
