In April 1776, John Walker & Company freighted the Duntreath with a load of coal, deliverable to Alexander-John Alexander of Grenada. Upon the Duntreath's arrival in Grenada, Bartlet, Campbell, & Company freighted it for a journey to Florida. In August 1776, after stopping on the St. Johns River, the Duntreath's captain James Edmonstone was captured by rebels and carried to Savannah. Now under the command of James Crichton, on its journey back to Grenada, the Duntreath was captured by the privateer ship Tyrannicide, but then recaptured and brought to New York for repairs. In January 1778, the Duntreath set out for Grenada again, but was captured by another rebel ship, the Three Sisters, before being recaptured and brought to Grenada. When no appearance was made to reclaim the Duntreath, Grenada's Vice-Admiralty Court had it auctioned. The owners of the Duntreath then made a claim to its insurance underwriters for a total loss, however the underwriters argued that because the auction money was deposited with Grenada's Vice-Admiralty Court, it was merely a partial loss. After the High Court of Admiralty found their case ineffectual, the ship's owners appealed to the Court of Session. Lord Gardenstone reported their bill, but the Court ruled it outside of their jurisdiction. Their bill was later remitted to Lord Braxfield, however, who reported it again; the Court then determined that the pursuers could only claim a partial loss.
