Invasion of Corumbá

The Corumbá invasion, in the context of the Paraguayan War, was the first Paraguayan movement within the Brazilian territory, starting the Mato Grosso Campaign. On December 23, 1864, López sent about five thousand men across the Paraguay River under the command of Vicente Barrios. This column attacked Fort Novo de Coimbra on the 27th, capitulating three days later; they advanced towards Albuquerque, reaching Corumbá on January 4, 1865.[1]

López highlighted about nine thousand men divided into two columns, one commanded by Colonel Vicente Barrios and the other commanded by Colonel Francisco Isidoro Resquín. The second column, which had four thousand soldiers, was responsible for operations further south in the province of Mato Grosso in the territory surrounding Dourados, taken on December 29, 1864. The first column, of about five thousand men, had as a mission to invade Corumbá and territories further north, reaching Coxim.[2]

The first obstacle was the Fort of Nova Coimbra, built by the Portuguese in the 18th century. The Paraguayans, divided into five infantry battalions and two cavalry columns, advanced on the fort on December 27, 1864, which was defended by only 195 Brazilians (155 military and national guards and the rest civilians), under the command of the lieutenant-colonel Hermenegildo de Albuquerque Porto Carrero, the Baron of Forte Coimbra. There were about 31 artillery pieces in the fort, with only 12 of them functioning. Paraguayans faced fierce resistance from Brazilians who, for three days, prevented the taking of the fort. The wives and relatives of officers and officers prepared powder cartridges, bandages, and treated the wounded as much as possible. With no resources to resist and far from reinforcements, the fort was evacuated in order, on the night of December 28th to 29th, in the Anhambaí gunboat. The fort remained occupied by Paraguayan forces until April 1868, when they abandoned it, leading their artillery and everything in it.[3]

Having overcome this obstacle, the column headed towards Corumbá following the trail of Porto Carrero, passing and invading Albuquerque district on January 1, 1865 without struggle. On January 4, the Paraguayans reached Corumbá, which at the time was commanded by the Colonel Carlos Augusto de Oliveira. When he heard that the Paraguayans had arrived in the city, he put his troops on a boat and went up the river towards Cuiabá, leaving the approximately 1,000 inhabitants to fend for themselves. This act infuriated the local military who tried to coward the colonel and some high-ranking military personnel who collaborated with the escape. Paraguayans plundered the city entirely by sending men into forced labor in Paraguay, leaving only children and women who are also forced into forced labor by Paraguayans in the same city.[4]

The total force of Brazilian soldiers deployed in the province of Mato Grosso reached just over 800 men. Given this and the fact that the region is extremely remote, the Paraguayan invasion was a success. Barrios' troops advanced to distant Coxim, hundreds of kilometers to the east in Mato Grosso.[5]
