Event of 1868: In the Passage of Humaitá, a Brazilian naval force succeeds in dashing past a Pa

Six Brazilian armored vessels dashed past the Paraguayan fortress of Humaitá on 19 February 1868, successfully exploiting its weakness.

The operation aimed to stop Paraguayan resupply by river and provide a propaganda victory. The squadron proceeded in a specific order. The fortress was considered impregnable, but the attackers found a weakness. The river levels fluctuated, rising unusually high in February 1868 before turning, making the passage imperative.
