Lieutenant John White commissioned HMS Cynthia on 10 July 1826 for the Packet Service. Fate

On 6 June, Cynthia'' was wrecked on Kendal Point, Barbados. She had sighted Barbados late in the afternoon of 5 June and Lieutenant White decided to lie-to for the night. Still, at one in the morning breakers were sighted close ahead and she ran aground. It proved impossible to get her off during the night and by daybreak it was clear that she was on a reef about two miles off the southern point of the island. She landed her mails but despite attempts by local boats to lighten her, she could not be got off and by mid-afternoon she was flooded, ending all hope of rescuing her.
