Francisco Espoz Ilundáin (17 June 1781 – 24 December 1836), being better known as Francisco Espoz y Mina, was a Spanish guerrilla leader and general. He was born in Idocin in Navarre. His father, Juan Esteban Espoz y Mina, and his mother, Maria Teresa Hundain y Ardaiz, belonged to the class of yeomen. Mina worked on the small family farm until 1808. When Napoleon endeavoured to seize Spain in that year he enlisted in the Doyle regiment, and then entered the guerrilla group commanded by his nephew Francisco Javier Mina. When Javier was captured by the French on 21 March 1810, seven men of the group chose to follow Francisco, and on April 1 of the same year the Junta of Aragon gave him the command of the guerrilleros of Navarre.
