Battle of Rio de Janeiro (1710)
The 1710 Battle of Rio de Janeiro was a failed raid by a French privateering fleet on the Portuguese colonial city of Rio de Janeiro in August 1710, during the War of the Spanish Succession. The raid was a complete failure; its commander, Jean-François Duclerc, and more than 600 men were captured. French anger over the Portuguese failure to properly hold, release, or exchange the prisoners contributed to a second, successful raid, the following year. Duclerc was assassinated while in captivity in March 1711; his killers (and their reason for killing him) are unknown. References
