Following independence, a navy was established under Colonel Pablo Zufriategui, a veteran of Artigas's campaigns and the 33 Easterners. As Captain of Ports ("Capitán General de Puertos"), he fought smuggling and in 1832 Zufriategui led the first sovereign engagement when the schooner "Aguila" chased off the pirate ship "Exquisit" from Uruguayan waters.
