The Battle of Kilometer 7 occurred during the Chaco War between Bolivian forces commanded by Lt Col Bernardino Bilbao Rioja defending Fort Saavedra and Paraguayan forces under Col José Félix Estigarribia, from 7 November 1932 to February 1933, and ended with a Paraguayan retreat to the northeast towards Gondra, later to be the site of the Battle of Campo Jordán.
