Ildefonso Sanjinés Rada (12 June 1812 – 2 December 1882) was a Bolivian military officer who served as Minister of War twice during the presidencies of Agustín Morales, Tomás Frías, and Adolfo Ballivián.

During the beginning of the battle, it is said that the rest of the army bet which of the two battalions, Belzu's or Sanjinés', would advance further into the enemy camp and would fight with more courage.

[8] Sanjinés was noted for being an implacable enemy of the Mariano Melgarejo and, in 1865, found himself the Battle of Cantería at the command of a rebellious division from Cochabamba.

Ultimately, Sanjinés and his accomplice, General Nicanor Flores, were defeated and he fled to Peru to escape the wrath of the "barbarian" Melgarejo.

Sanjinés was a member of said assembly as a representative elected by the La Paz Department and was promoted to the rank of divisional general by the end of that year.

[15] After the sudden death of Morales', Sanjinés was one of the most important officers who maintained public order, which had been altered as a result of the President, supporting the constitutional succession of Tomás Frías.
