In anticipation of this change, and as recent events at the Gambia and Sierra Leone had shown the necessity for an increase in the strength of the detachments, No. 2 Company of the 1st West India Regiment, under Captain W.J. Chamberlayne, embarked at Jamaica for Africa in the Sir George Pollock on February 19th, 1856. It arrived in the Gambia on April 1st, and detachments to McCarthy's Island, 179 miles up the River Gambia, and to Fort Bullen, were at once furnished from it.

No other change in the distribution of the regiment took place in this year, with the exception that No. 5 Company, under Captain R. Hughes, was moved from Jamaica to Barbados in December.

In January, 1857, No. 1 Company from Demerara, and Nos. 4 and 7 from Barbados, embarked on board the troopship Perseverance, for Africa, under the command of Brevet Lieutenant-Colonel Clarke, and Captains Hughes and Macauley, arriving at Sierra Leone on February 28th.

Nos. 1 and 7 Companies were there disembarked, and the Perseverance then proceeded to the Gambia, where No. 4 Company was landed. In accordance with the scheme that the remaining four companies of the regiment should be stationed at Jamaica, No. 5 Company rejoined there from Barbados on April 17th; but, two months later, the scheme was again revised, and, on June 4th, the head-quarters and four companies embarked for Nassau, New Providence, under Lieutenant-Colonel F.A. Wetherall.

The detachments on the West Coast of Africa were very much subdivided, that of the Gambia furnishing garrisons for Fort Bullen, Cape St. Mary, and McCarthy's Island; and that of Sierra Leone a garrison for Waterloo. In April, 1857, the garrison of Fort Bullen was reinforced by No. 2 Company under Captain Chamberlayne from Bathurst, in consequence of disturbances having broken out between the King of Barra and one of his principal chiefs named Osumanu Sajji, and was withdrawn in May, on tranquility being restored.

In August, 1858, the natives of Sherbro threatened to plunder the British factories that had been established on Sherbro Island, and stopped the trade, and for the protection of the lives and property of the Consul and British subjects, a detachment of the 1st West India Regiment, under Captain R. Hughes, proceeded in H.M.S. Spitfire to Sherbro Island on September 1st. They there landed and remained until October 2nd, when, all fears of an attack being at an end, they returned to Sierra Leone. In January, 1859, however, another attack was threatened by the Mendis, and a detachment of the 1st West India Regiment, under Captain Luke, was sent for the protection of the factories in H.M.S. Trident on January 15th, returning to Sierra Leone on February 18th.

In September and October, 1858, Captain Luke, 1st West India Regiment, who was then on leave of absence on the Gold Coast, served with the expeditionary force against the rebel Krobo stronghold of Krobo Hill. Captain Cochrane, Gold Coast Artillery, commanding the force, in concluding his despatch of October 26th, 1858, says: "It is not too much to say that all who have joined the expedition have done their best to further its interests, but I beg especially to call your Excellency's notice to the voluntary services of Captain F.H. Luke, of the 1st West India Regiment, whose energy, zeal, and disinterestedness, have been warmly commended by every officer here, and are deserving of honourable mention."

In February, 1859, the town of Porto Lokkoh, distant some forty miles from Sierra Leone, and on the Sierra Leone River, was burned and pillaged by a body of Soosoos who had, for some time back, established themselves at Kambia, on the Great Scarcies River. For previous outrages committed by them, Kambia had been bombarded by a naval squadron under Commodore Wise on February 1st, 1858, after which the Soosoos had entrenched themselves in a stockaded work, or war fence, near Kambia. There they had been suffered to remain, but the destruction of Porto Lokkoh, the chief entrepôt of the Sierra Leone trade, necessitated further measures being taken against them.

Consequently, on March 20th, 1859, the Governor of Sierra Leone, Colonel Stephen Hill, proceeded with a force of 203 men of the 1st West India Regiment, under Major A.W. Murray, in H.M.S. Vesuvius, Trident, and Spitfire, to the Great Scarcies River, where they arrived at daybreak on the 22nd. The officers of the regiment serving with the expedition were Major Murray, Brevet-Major Pratt, Lieutenants Fitzgerald, Mackay, and Mawe, Ensigns Ormsby and Temple. Colonel Hill, in his despatch, says:

"The troops having landed to the right of the town, I formed the detachment of the 1st West India Regiment, under Major Murray, into four divisions; and the marines formed, under the command of Captain Hill, 2nd West India Regiment, A.D.C., another division. A party of the former corps, acting as gunners, accompanied the Marine Artillery, who took charge of two mountain howitzers.
