The offensive in the West was originally planned for 12 November 1939. It had to be carried out by 67 divisions organized in three army groups. Yet controversies in the command of the German armed forces, shortages of war materials, and severe winter caused that the date of invasion had to be postponed; and it was postponed 29 times.
