The action of 31 May 1796 was a small action during the French Revolutionary Wars in which a Royal Navy squadron under the command of Commodore Horatio Nelson, in the 64-gun third-rate ship of the line HMS Agamemnon, captured a seven-vessel French convoy that was sailing along the coast from Menton to Vado in the Mediterranean. The British succeeded in capturing the entire convoy, with minimal casualties to themselves. Nelson had received the news that the French were trying to take supplies to St Pierre d'Acena for the siege of Mantua. He therefore set out to intercept any such attempt.
