In 1793-4 Glatton made one round trip to China for the East India Company. Her captain was Charles Drummond and her First Lieutenant was William Macnamarra. Drummond had commanded an earlier Glatton and would command a later one too; Macnamarra too would go on to command a later Glatton on a trip to China for the Company. Glatton's letter of marque was dated 22 August 1793. The letter of marque permitted her, while under Drummond's command, to assist in the capture of the French brig Franc.
