On March 12, 1938 the 8th Army of the German Wehrmacht crossed into Austria. Many welcomed the coming of the Nazis as liberators and the troops were greeted by cheering German-Austrians citizens with Nazi salutes, flags and flowers. As a result, the Nazi annexing of Austria is sometimes called the Blumenkrieg (war of flowers), though the official name was Unternehmen Otto.
For the Germans, it was seen as the first big test of their war machine although as it turned out, no actual fighting took place.
