In 1906, Alfonso graduated from the Academia Militar de Toledo (Military Academy of Toledo). In 1910, he trained as a pilot in
France. Upon returning to Spain, he successfully became one of the first and most distinguished aviators in the Spanish military. He served as chief of aerial operations for the 1925 amphibious landings at
Al Hoceima in
Morocco. In May 1930, Alfonso was a passenger on the
Graf Zeppelin flight from
Seville to
Brazil. He then continued in the
Graf Zeppelin to New York City and visited President
Herbert Hoover in Washington, D.C., before returning to Spain. On 27 February 1931, Alfonso was named Chief of Staff of the
Spanish Air Force and Commander of the First Aero District by his cousin King
Alfonso XIII. After the founding of the
Second Spanish Republic on 14 April 1931, Alfonso was exiled to
London. When he returned to Spain in 1932, he was imprisoned at Villa Cisneros (now
Dakhla, Western Sahara). On 1 January 1933, Alfonso and some thirty other monarchist prisoners escaped in a boat, travelling 1800 miles to
Lisbon. In 1937, after the start of the
Spanish Civil War Alfonso returned to Spain to head the aerial forces of General
Francisco Franco. At the end of the war, he was promoted to general. He was made head of the Second Division Air Force in 1940. Three years later, he was promoted to
brigadier general. For many years, Alfonso was the unofficial representative in Spain of the
Count of Barcelona, the son and heir of King
Alfonso XIII. In 1941, Alfonso was godfather for the Count of Barcelona's younger son
Alfonso. In 1945, Alfonso resigned his position in the Spanish Air Force to show his support for the Lausanne Manifesto, a manifesto of the Count of Barcelona arguing for the restoration of the monarchy. This decision put an end to his military career, although he continued to pilot aircraft as a civilian. ==Marriage and issue==
