Marcos Ana

Fernando Macarro Castillo (20 January 1920 in Alconada – 24 November 2016 in Madrid), better known by his pseudonym Marcos Ana, was a Spanish poet and is considered by numerous sources Spain's longest serving political prisoner.

He told his story in the 2007 memoir Tell Me What a Tree Is Like He was born in the hamlet of San Vicente, which belongs to the municipality of Alconada in Salamanca, although he spent his childhood in Ventosa del Río Almar, also in the same province, within a very poor family of day laborers, deeply Catholic.

His education was limited, and at the age of twelve or thirteen, he left school and began working as a shop assistant to contribute to the family income.

He joined the front at the outbreak of the Spanish Civil War in 1936, in the "Liberty" militia battalion of the JSU, fighting in the Peguerinos area of the Sierra de Guadarrama during the early days of the conflict.

Before the total siege of the capital, he managed to escape towards Levante, like many other Republican army leaders, Popular Front organizations, or Republic state officials.
