Read this: At the Battle of Pulo Aura, which was probably the company's most notable naval victory, Nathaniel Dance, Commodore of a convoy of Indiamen and sailing aboard the Warley, led several Indiamen in a skirmish with a French squadron, driving them off. Some six years earlier, on 28 January 1797, five Indiamen, the Woodford, under Captain Charles Lennox, the Taunton-Castle, Captain Edward Studd, Canton, Captain Abel Vyvyan, and Boddam, Captain George Palmer, and Ocean, Captain John Christian Lochner, had encountered Admiral de Sercey and his squadron of frigates. On this occasion the Indiamen also succeeded in bluffing their way to safety, and without any shots even being fired. Lastly, on 15 June 1795, the General Goddard played a large role in the capture of seven Dutch East Indiamen off St Helena.

How did the Indiamen get to safety by firing just one bullet in 1797?
