This latter incident finally convinced the British Foreign Office to reassert its sovereignty claim over the islands. Throughout much of 1832, the United Provinces did not have a government representative in the islands. The Buenos Aires government commissioned Major Esteban Mestivier as the new governor of the islands, to set up a penal colony, but when he arrived at the settlement on 15 November 1832 his soldiers mutinied and killed him. The mutiny was put down by Major José María Pinedo, commander of the United Provinces schooner "Sarandí". Order was restored just before the British arrived.
