Gen. Benjamín Guillermo Hill Salido was a military commander during the Mexican Revolution. He was a cousin of revolutionary general and later president Álvaro Obregón Salido, whom he supported from the beginning of his rise to power. He was called "Obregón's lost right arm," alluding to the arm his cousin lost in the 1915 Battle of Celaya, defeating General Pancho Villa.

Álvaro Obregón Salido was a Mexican military general and politician who served as the 46th President of Mexico from 1920 to 1924. Obregón was re-elected to the presidency in 1928 but was assassinated before he could take office.

Gutiérrez was appointed provisional President of Mexico by the Convention of Aguascalientes, a move that Venustiano Carranza (1859–1920) found intolerable. In the ensuing war, Obregón fought for Carranza against the convention.
