WW2 · SEP 1938

Why didn’t Britain and France stop Hitler in 1936–38?

The seminar question: “Britain and France could probably have stopped Hitler cheaply in 1936–38. Why didn’t they?”

From 1936 to 1938 Hitler remilitarized the Rhineland, backed Franco in the Spanish Civil War, annexed Austria and demanded the Sudetenland. Britain and France answered with appeasement, and at Munich in September 1938 they granted the Sudetenland rather than risk war, a price paid by Czechoslovakia.

Map of Appeasement and the road to WW2 (Sep 1938)
SEP 1938 · THE WAR ROOM — WW2, 1936–1945

In 1936, France had the military strength nearby to intervene when German troops entered the demilitarized Rhineland. Britain and France protested, and the German move stood. Here was a breach of the postwar settlement that France had the means to resist. Why did it hold back?

The short answer

THE TURNING POINT

Munich, 30 September 1938. The agreement at Munich gave Hitler reason to expect that pressure would win concessions. Stalin, whose government had been excluded, had reason to doubt a reliable Western front against Germany. Both conclusions helped make the Nazi–Soviet Pact possible.

What it changed

Czechoslovakia becomes vulnerable. Czechoslovakia’s border defenses lay in the Sudetenland. Losing them left the country exposed; Germany seized the rest in March 1939, gaining the Škoda arms works as well.

Stalin considers a German agreement. The Soviet Union’s exclusion from Munich added to its distrust of Britain and France. An agreement with Berlin came to look like a way to gain time and a security buffer.

Britain guarantees Poland. Britain’s guarantee to Poland after Prague made resistance to further expansion a clearer commitment. Hitler read it as another bluff, raising the danger in the next crisis.

The full answer, argued

Stopping Hitler meant accepting the possibility of another mass war. Leaders faced economic pressure, divided opinion, and forces that needed more preparation; delay did give them useful time to rearm. They also treated his demands as disputes over particular borders. Hitler saw concessions as steps toward a larger racial empire, so the bargain they hoped would settle the dispute encouraged further demands.

An interesting fact

French intelligence believed that nearly 300,000 German troops were in and behind the Rhineland zone in March 1936—about ten times the actual number. Only about 3,000 soldiers crossed the Rhine bridges. Hitler later called the forty-eight hours after the march the most nerve-racking of his life. A familiar story holds that the troops had orders to retreat at the first French shot, but historians now doubt it.
