The Liberal Party rose against the Conservative government of President Manuel Antonio Sanclemente on 17 October 1899, launching the Thousand Days' War. Seeking a strategic advantage, Liberal rebels moved to seize control of the Magdalena River, the principal waterway linking the interior of Colombia to Bogotá.
A Liberal flotilla of converted passenger steamships and a dredge challenged Conservative control of the Magdalena River near Gamarra on 24 October 1899. The rebel vessels temporarily halted Conservative movement downriver until that night, when two Conservative gunboats commanded by General Diego de Castro engaged and destroyed the Liberal flotilla.
With the destruction of the rebel flotilla, Conservative forces retained control of the Magdalena River, denying the Liberals their objective of severing riverine transportation to Bogotá. This outcome secured a key logistical artery for the Conservative government early in the Thousand Days' War and set the tone for subsequent military operations.
