[1] As Monarch, Davidson, master, was sailing to England from Quebec with a cargo of wood, on 16 September 1800 she encountered the French privateer Bellone, which captured her.

However, four days later, HMS Immortalite recaptured Monarch, of 645 tons (bm), and sent her into Plymouth.

Monarch was part of a convoy under escort by HMS Seahorse that also included Northampton, Manship, Sarah Christiana, Comet, Sovereign, Caledonia, Ann, Princess Mary, Varuna, Carron, Elizabeth, General Stuart, and Friendship.

Homeward bound, she reached at St Helena on 13 June and arrived at the Downs on 20 August.

[4] On the way she and Earl Spencer rescued all of the passengers and all but 16 of the crew of Travers, which had hit a rock on 7 November at 15°38′N 94°20′E / 15.633°N 94.333°E / 15.633; 94.333.

[4] In March, Hawes joined several other EIC captains (Kymer of Lord Castlereagh and Hemming of Earl Spencer, in a letter of protest against the British Royal Navy's having impressed seamen from Indiamen.

[13] On 2 May 1809 she departed from the Sandheads with a convoy of four other Indiamen and several smaller vessels, all under the escort of HMS Victor.

On 24 May a storm split the convoy and Victor and the small ships separately lost touch with the Indiamen.

The three remaining Indiamen, Streatham, Europe, and Lord Keith continued on their way while hoping to meet up with Victor.

[14] Lord Keith too exchanged broadsides with Caroline and was damaged; still, she escaped and sailed to Penang to repair.

Monarch, Earl Spencer, and Lord Keith then sailed together and reached St Helena on 14 November; they arrived at the Downs on 19 January 1810.

[4] As HMS Nyaden was carrying dispatches from Lisbon back to Great Britain, a flotilla of five French ships of the line that had escaped from Lorient spotted her.
