Those forces failed to prevent continuing unrest

German expansion had begun in 1938 with the annexation of Austria and then continued with the occupation of the Sudetenland and then all of Czechoslovakia in 1939. Both had been accomplished without igniting hostilities with the major powers, and Hitler hoped that his invasion.
