On 8 April 1793, shortly after the outbreak of war with France Captain John Richards acquired a letter of marque.

[2][a] Captain Richards was dismissed the company's service on 18 February 1801, after he admitted to having smuggled furs, "contrary to the Duty" he owed the HBC.

[5] The HBC sold King George in May 1811 to Daniel and Samuel Brent & Sons.

She then became a Northern Fisheries whaler, possibly after the Brents sold her to Elvgin & Co. On 19 April 1814 Lloyd's List reported that King George, Gordon, master, had had to put into Aberdeen leaky while sailing to the whaling grounds at Davis Strait.

[6] The following data is from Coltish:[7] King George, Proven, master, sailed from Gravesend on 4 April 1822 for Greenland.
