Buenos Aires attempted to retain influence over the settlement by installing a garrison, but a mutiny in 1832 was followed the next year by the arrival of British forces who reasserted Britain's rule. The Argentine Confederation (headed by Buenos Aires Governor Juan Manuel de Rosas) protested against Britain's actions, and Argentine governments have continued since then to register official protests against Britain. The British troops departed after completing their mission, leaving the area without formal government. Vernet's deputy, the Scotsman Matthew Brisbane, returned to the islands that year to restore the business, but his efforts ended after, amid unrest at Port Louis, gaucho Antonio Rivero led a group of dissatisfied individuals to murder Brisbane and the settlement's senior leaders; survivors hid in a cave on a nearby island until the British returned and restored order. In 1840, the Falklands became a Crown colony and Scottish settlers subsequently established an official pastoral community. Four years later, nearly everyone relocated to Port Jackson, considered a better location for government, and merchant Samuel Lafone began a venture to encourage British colonisation.
