SIR--I have the honour to inform you, for the information of My Lords Commissioners of the Admiralty, that I have received my appointment to the South East Coast of America; but, as I did not apply for that command, I beg most respectfully to request their Lordships will be pleased to inform me of their reason for removing me from the Cape of Good Hope and West Coast of Africa to an inferior command.--I have the honour to be, sir, your obedient servant, (Signed) HENRY KEPPEL, Rear-Admiral. [Sidenote: Sierra Leone.] Appointed Lieutenant Wilkinson Acting Commander, and Mr. Turner, Flag Lieutenant. The expedition had started to punish the King of Badiboo, who, when called on to pay a fine of bullocks for having robbed British merchants, sent in reply to Governor D’Arcy at Bathurst, he would fight him, and if he was not assisted by the French, thrash him to boot! Colonel Hill, Governor of Sierra Leone, having sent all his troops, was anxious for the assistance of the Navy. [Sidenote: Feb. 13.] Embarked the Governor under salute and manned yards. Weighed for the Gambia, _Arrogant_ and _Falcon_ having preceded. [Sidenote: Gambia, Feb. 16.] Nearing the land, signalman reported masts of a ship at anchor to the N.W. Steered towards her. On getting within distance, she signalled, “You are standing into danger.” This was the _Arrogant_, my old friend Edmonstone of the Naval College, the cleverest fellow there, who passed out six months before his allotted two years: no better fellow, but chance had made me his senior. My reply was, “Weigh immediately and follow me.” Steamed into the Gambia, _Arrogant_ in company. Came to in 15 fathoms off Bathurst. [Sidenote: Feb. 17.] 1 P.M.--_Arrogant_ proceeded up the river to join the expedition which left Bathurst on Friday. 4 P.M.--_Falcon_ arrived, but being out of coal came to. At 4.30 P.M., _Forte’s_ services not being required, steamed out of the river. [Sidenote: Feb. 22.] Arrived at Sierra Leone. Having taken in 135 tons of coal, steamed out. [Sidenote: Feb. 25.] 4 A.M.--Tornado came off, cool and refreshing. Made sail after the strength had passed. Departed this life, Mr. Keating, boatswain, a former shipmate in _Dido_. Poor fellow, he leaves a wife and three young children. [Sidenote: Accra, Mar. 3.] 3 P.M.--Came to off Accra; landed in the evening. [Sidenote: Mar. 4.] 11 A.M.--Re-embarked under salute from the fort. 9.30 P.M.--Weighed. [Sidenote: Mar. 5.] 1.30 P.M.--Came to in 7 fathoms off a village called Jellacoffy, two miles to the eastward of Cape St. Paul, a good place for stock and fruit. 4.30 P.M.--Weighed. [Sidenote: Fernando Po, Mar. 10.] Came to in a cove to the westward of Cockburn Cove, Fernando Po. Found _Bloodhound_, 3, paddle wheel, steam vessel, Lieutenant Commander Francis W. Bennett. Saluted Spanish flag and returned salute of Spanish brig.
