techniques and devised new ground-attack tactics which were passed on to the Luftwaffe. His experiences in pin-point ground assaults were used by Ernst Udet, a proponent of the dive bomber and leading supporter of the Junkers Ju 87 to push for Stuka wings. Wolfram von Richthofen, an opponent of Udet's, used them to push for the opposite: Schlachtflieger dual combination fighter-bombers. After trials with Henschel Hs 123s, Bf 109s and Ju 87s, the Junkers was selected to undergo trials for the dive bomber role. During his time in Spain, he developed early gasoline and oil bombs, suggested the quartering of personnel on trains to aid in relocation, and following the Nationalist victory was awarded the ‘Spanish Cross in Gold with Swords and Diamonds' for his contributions. On 24 May 1938 Galland left Spain and was replaced by Werner Mölders. Before leaving he made ten flights in the Bf 109; deeply impressed with the performance of the aircraft, it persuaded him to change from a strike pilot to a fighter pilot. Galland's fellow student and friend at the Kriegsschule in Dresden, Johannes Janke, later said of him "a very good pilot and excellent shot, but ambitious and he wanted to get noticed. A parvenu. He was crazy about hunting anything, from a sparrow to a man." Staff post in the RLM From May to August 1938, Galland took leave and visited Spanish Morocco. On his return to Germany, he was ordered to the headquarters of the Reichsluftfahrtministerium (RLM – Ministry of Aviation) where he was tasked with preparing recommendations on the subject of close air support. Galland favoured the virtually simultaneous attack of the air force before the Army advance, leaving their opponents no time to recover. While this reasserted the lessons of World War I, some of the Officer Corps were still pessimistic as to whether that kind of coordination was possible. Galland also adopted the Italian suggestion of heavy armament and criticised the light machine guns in early German fighter aircraft and pointed to the advantages of multi-gun configurations (combining machine guns with cannon). These proved successful in the Bf 109 and Focke-Wulf Fw 190. He also recognised the innovation of drop tanks to extend the range of aircraft as well as the need for specialised tactics for escorting bomber fleets; Galland did not subscribe to the prevailing idea in the Luftwaffe (and RAF) that the bomber "would always
