The Passage of Humaitá was a riverine operation during the Paraguayan War where six Brazilian armored vessels dashed past a fortress. The attempt on 19 February 1868 succeeded, aiming to stop resupply and secure a propaganda victory. Some authors view it as the war's turning point, though others note limited military significance.

Background and detail
Background. The Paraguayan War was the most lethal in South American history. The Fortress of Humaitá, considered impregnable, prevented enemy shipping from ascending the River Paraguay. Allied forces needed to proceed up the river, but frontal attacks failed. To starve out Humaitá, stopping river resupply was necessary, creating a need for a propaganda victory by late 1867.
Execution. The operation involved six Imperial Brazilian Navy armored vessels. The squadron proceeded in a specific order on 19 February 1868. The attackers exploited the fortress's weakness. The river had fallen previously, but rose unusually high in February 1868 before turning. Shallow draught monitors arrived below Curupaty in February, supporting the operation's timing and logistics.
