1415Southampton PlotConspiracy to replace Henry V with Edmund Mortimer uncovered before the Agincourt campaignA group of English nobles conspired to assassinate Henry V and place Edmund Mortimer, Earl of March, on the throne before the king's planned invasion of France. Mortimer himself revealed the plot to Henry, and the ringleaders were swiftly tried and executed at Southampton in early August 1415.
