German involvement in the Spanish Civil War

German involvement in the Spanish Civil War commenced with the outbreak of war in July 1936, with Adolf Hitler immediately sending in air and armored units to assist General Francisco Franco and his Nationalist forces. In opposition, the Soviet Union sent in smaller forces equipped with more advanced equipment to assist the Republican government, while Britain and France and two dozen other countries set up an embargo on any munitions or soldiers into Spain.
