 Sir Charles Rowley to the acting command of the Euryalus 42, from which frigate he returned to the Nautilus on the 21st of April following. In May, 1822, he paid that sloop off, at Portsmouth; and in Jan. 1823, received a commission appointing him to the Espiegle, of similar force, on the Cape of Good Hope station, where he was promoted to the command of the Ariadne 20, in Oct. 1824.

The Lords of the Admiralty, in consequence, on the arrival of the Ariadne in England, ordered three captains to form a court of enquiry into the truth of the statements made.
