The only information that we have about this corsair is contained in a letter from Josť Gervasio Artigas to Governor Vega, dated December 2, 1817. This letter says of Banda Oriental: "a couple of days after setting sail, it captured four Portuguese ships, one of them having made it Colonia del Sacramento on the 28th of the previous month"
It is thought to have been a classic barkentine, made in Baltimore, USA, with a weight of 240 tons, a crew of 80 men, and armed with ten 18-pound cannons.
A corsair is a naval unit that, motivated by the prospect of gains, offers its services to one belligerent party in a conflict. After being authorized by a "corsair patent", it cruises the seas, following and attacking both merchant and military fleets, confiscating their cargoes and taking possession of their ships.
When war broke out between Portugal and Artigas, Artigas had no navy and no resources, but by using corsairs, he was able to create a fleet without compromising his territory and his sovereignty. He reclaimed the right of the people of the Banda Oriental to attack and destroy their powerful maritime enemy.
