She famously carried the Rosetta Stone to Woolwich, and then the Admiralty commissioned her into the Royal Navy as the 40-gun fifth-rate frigate HMS Egyptienne.

[1] The foremost maindeck port was found too curved in the bow to admit a gun, so Égyptienne received only 48 cannon instead of 50.

[2] In 1801 Napoleon required reinforcements in Egypt so the frigates Égyptienne and Justice, each carrying troops and munitions, left Toulon.

[3] Admiral Lord Keith commander of the naval forces, gave the value of Égyptienne for prize money purposes at £23,665 0s 0d.

[4] The British took Égyptienne into service on 27 September and Captain Thomas Stephenson sailed her to Britain;[1] on this voyage she carried Colonel Tomkyns Hilgrove Turner, who was bringing the Rosetta Stone to England.

She commissioned under Captain Charles Fleeming (or Elphinstone or Fleming) in April 1803 and initially sailed in the English Channel and off the coast of France.

Fleming remarked in his report that she was an extremely fast vessel that had several times eluded British frigates, including Egyptienne herself on one occasion.

After the battle, Admiral Robert Calder requested a court-martial to review his decision not to pursue the enemy fleet after the engagement.

The court martial ruled that Calder's failure to pursue was an error of judgment, not a manifestation of cowardice, and severely reprimanded him.

[13] Paulina, which Egyptienne captured on 20 November, was a 12-gun Spanish letter of marque, under the command of Don Antonio Acibal.

[14] On 24 December off Rochefort, Egyptienne, under Lieutenant Handfield, his promotion still not confirmed, and Captain Frederick Lewis Maitland's HMS Loire captured the 40-gun Libre, Capitaine de Frégate Deschorches commanding.

Egyptienne's boats cut out the privateer Alcide from Muros on 8 March 1806 and under incessant but ineffective fire from two shore batteries.
