Blitzkrieg was first seen in which invasion?

• A. Poland in 1939
• B. France in 1940
• C. Norway in 1940
• D. Austria in 1938

Answer: (A)

Blitzkrieg is a style of warfare that relies on speed, surprise, and coordinated action between tanks, infantry, artillery, and air power to break through defenses and disrupt an enemy’s ability to respond. The first clear demonstration of this approach in practice happened during the German invasion of Poland in 1939. German forces used fast armored spearheads and mobile troops, supported by air superiority and close coordination, to push through Polish defenses and encircle them, leading to a rapid collapse of Polish resistance. This showed how rapid, concentrated combined-arms action could achieve a decisive result in a short time.

Austria in 1938 was mainly a political annexation with limited organized combat; France in 1940 would later apply similar ideas on a larger scale, but after Poland; Norway in 1940 also used fast tactics. Therefore, the earliest instance is the invasion of Poland in 1939.
