The Manstein plan has often been called "Operation Sichelschnitt", a literal German translation of "sickle cut", a catchy expression used after the events by Winston Churchill. After the war, German generals adopted the term, which led to a misunderstanding that this was the official name of the plan or at least of the attack by Army Group A. The German name was Aufmarschanweisung N°4, Fall Gelb as issued on 24 February 1940 and the manoeuvre through the Ardennes had no name.
