During the autumn of 1937, Hitler secured Mussolini's support to annex Austria (Mussolini was originally apprehensive of the Nazi takeover of Austria) and informed his generals of his intentions to invade both Austria and Czechoslovakia.[23] Getting Mussolini to approve political intrigue against Austria was a major accomplishment, as the Italian Duce had expressed great concern previously in the wake of an Austrian SS unit's attempt to stage a coup not more than three weeks after the Röhm affair, an episode that embarrassed the SS, enraged Hitler, and ended in the assassination of Austrian Chancellor Engelbert Dollfuss on 25 July 1934.[24] Nonetheless, to facilitate the incorporation of Austria into the greater Reich, the SD and Gestapo went to work arresting people immediately, using lists compiled by Heydrich.[25] Heydrich's SD and Austrian SS members received financing from Berlin to harass Austrian Chancellor von Schuschnigg's government all throughout 1937.
