She sailed on 6 October and joined the fleet, which did not leave Spithead until 16 November. Bad weather forced the fleet to return to port after having sustained heavy losses. The fleet attempted to sail again on 9 December, but bad weather forced most of the warships to return to port on 26 January. The fleet finally succeeded in leaving on 20 March. Ponsborne arrived at Grenada on 24 March and landed her troops who were required to put down Fédon's rebellion. She was delayed leaving the harbour. Two days later she stranded on La Baye Reefs when leaving the harbour and became a total loss.[1] Her crew was saved.[7]
