Alonso de Contreras (Madrid, Spain, 6 January 1582 - 1641), was a Spanish sailor (captain of a frigate), soldier (captain of infantry and then of cavalry), privateer, adventurer and writer, best known as the author of his autobiography; one of the very few autobiographies of Spanish soldiers under the Spanish Habsburgs and possibly one of the finest, together with the True History of the Conquest of New Spain (Historia Verdadera de la Conquista de la Nueva España) by Bernal Diaz del Castillo. Biography Born to a very poor family he enrolled in the army at the young age of 15 (in his autobiography he says 14 but the date he gives, September 1597, corresponds with 15) using his mother's name, Contreras. J.B. Trend's account is that he ran away to enlist after stabbing a school-fellow in Madrid at the age of 13. He traveled to Flanders but soon deserted and traveled to Malta where, for the following six years, he would soldier in privateering ships under the banner of the Order of Malta. During this time he encountered countless risks, fights and adventures. He deserted several times, mainly due to fights in which he was involved. He also learned navigation by observing the pilots do their work and was soon given command of ships. He knew the eastern Mediterranean very well and used this knowledge to write a sailing directions of the entire Mediterranean. The original manuscript of this work is kept today, together with the original manuscript of his autobiography, at the Spanish National Library in Madrid (Biblioteca Nacional de Madrid). After six years he returned to Castile where he applied for and got a commission as an ensign and he visited his mother. His orders were to recruit his soldiers, as was customary then, and, under the command of his captain, go to Extremadura. There is an obscure incident where, in the small Morisco town of Hornachos, he found a cache of arms in a house where one of his soldiers was quartered. He was told by the local authorities to say nothing but years later he was accused and tried for plotting a rebellion. He is not very clear on this incident and it could well be that there was more to it than he intimates.
