Second British invasion of the Río de la Plata; John Whitelocke lands at Ensenada on an attempt to recapture Buenos Aires and is defeated by the locals.
The British invasions of the River Plate were two unsuccessful British attempts to seize control of areas in the Spanish colony of the Viceroyalty of the Río de la Plata that were located around the Río de la Plata in South America — in present-day Argentina and Uruguay. The invasions took place between 1806 and 1807, as part of the Napoleonic Wars, when Spain was an ally of Napoleonic France.
