During the Brazilian War of Independence, Brazilian forces imposed a naval blockade on Montevideo, the last Portuguese stronghold in the Cisplatina province. Portuguese naval forces, consisting of a captured schooner and three armed transports, had endured the blockade but eventually resolved to break through it on 21 October 1823.
The Brazilian and Portuguese naval forces clashed off Montevideo on 21 October 1823 in one of the few conventional naval engagements of the war. Despite heavy fighting, neither side succeeded in sinking or capturing enemy vessels, and the Portuguese ultimately retreated back into the port, leaving the Brazilian blockade intact.
With the blockade unbroken, the Portuguese position in Montevideo became untenable. Approximately one month after the battle, Portuguese forces surrendered the city, ending the last significant Portuguese resistance in the Cisplatina and effectively concluding the Brazilian War of Independence.
