During this voyage she engaged in a notable combat action at night with two British warships.

Mary entered Lloyd's Register for 1806 with H. Crow, master, Aspinal, owner, and trade London–Africa.

At 10pm, HMS Dart, Commander Joseph Spear, and Wolverine, Commander Francis Augustus Collier, came upon a ship that they suspected was a French privateer and that kept up a running fight until morning, only surrendering after her captain and several of her crew had been wounded, of whom six later died.

Commander Spear gave him a letter of praise for his determined resistance and the fight became something of a sensation; on his return home Crow received honour, glory, and a substantial reward for his gallantry.

[5] Lloyd's Register for 1807 showed Mary's master changing from Crow to J.M'Neal, her owner from Aspinal to Lees, and her trade from Liverpool–Africa to Liverpool–Hayti.

[12] By 1821 Mary's owners were Daniel Bennett & Co and John Lydekker (or Liddereid), her master was E. Reed, and her trade was London–Southern Fishery.

The crew was suffering from scurvy but Mary had gathered 1600 barrels of whale oil.

[16] Lloyd's List reported on 4 November 1825 that Mary, Reed, master, was lost on Jarvis's Island.

Mary had lost her masts, she was half full of water, and her back was broken.

[16] They were fortunate that it was the rainy season; they were able to save rain water in casks salvaged from the wreck.

Vansittart arrived at Sydney in July with 16 crew members from Mary, including the second officer.
