the Army. Less than a year after being named was removed from office because of disagreements with the government regarding the strategy for defending the Chaco, "The Chaco should be advocated abandoning it," he argued, that is, the point was not occupy the land but to destroy the enemy. However, as the war against Bolivia seemed inevitable, the government decided that Lieutenant Colonel Estigarribia was the man who was needed in the Chaco. He was then 44 years. Small of stature, so peaceful, introspective, or his personality or his austere uniform of campaign-whose sleeves were invariably short-set him apart from the rest of the officers. Chaco War The definition of the Chaco War would be a war of communications in which the handling of space and time would be essential. He was determined for the Paraguayan government to accept its general mobilization plan and the beginning of the first offensive surprise Paraguay (September-December 1932) before Bolivia could mobilize its resources.
