The action of 9 September 1796 was an inconclusive minor naval engagement between small French Navy and British Royal Navy squadrons off northeastern Sumatra, near Banda Aceh, during the French Revolutionary Wars. The French squadron comprised six frigates engaged on a commerce raiding operation against British trade routes passing through captured parts of the Dutch East Indies, and posed a considerable threat to the weakened British naval forces in the region. The British force consisted of two 74-gun ships of the line hastily paired to oppose the eastward advance of the French squadron.
