context_page_description: The Brazilian monitor Alagoas was the third ship of the Pará-class river monitors built for the Brazilian Navy during the Paraguayan War in the late 1860s. Alagoas participated in the Passage of Humaitá in February 1868 and provided fire support for the army for the rest of the war. The ship was assigned to the Upper Uruguay Flotilla after the war. Alagoas was transferred to Rio de Janeiro in the 1890s and participated in the Fleet Revolt of 1893–94. The ship was scrapped in 1900.
context_section_description: Alagoas carried a single 70-pounder Whitworth rifled muzzle loader (RML) in her gun turret. The 70-pounder gun had a maximum elevation of 15°. It had a maximum range of 5,540 meters (6,060 yd). The 70-pounder gun weighed 8,582 pounds (3,892.7 kg) and fired a 5.5-inch (140 mm) shell that weighed 81 pounds (36.7 kg). Most unusually the gun's Brazilian-designed iron carriage was designed to pivot vertically at the muzzle; this was done to minimize the size of the gunport through which splinters and shells could enter.
