On December 13th, 1832, the Hastings company of volunteers, with that of Waterloo, marched from the village of Waterloo towards Cobolo, distant by road some thirty miles, with orders to capture and bring in the leaders of the rebels. Next morning, as this force was approaching Cobolo, the Acoos, who were concealed in the bush, fired upon the head of the column, and the volunteers at once, and without firing a shot, turned and ran in the greatest confusion; nor did they recover from their panic till they had reached Waterloo. The Acoos pursued the fugitives for some little distance, and killed seven of their number. The rising, originally trivial, had now, through the shameful behaviour of the volunteers, become serious. The news of the defeat spread with great rapidity among the unruly tribes on the frontier of the Colony; and a Mohammedan priest, proclaiming himself a prophet, placed himself at the head of the movement. The Governor acted with promptitude; and recognising the great danger of delay, despatched, on December 17th, all the available men from the garrison of Sierra Leone, under Lieut.-Colonel Hingston, Royal African Corps. The recruiting company of the 1st West India Regiment accompanied the force, under the command of Lieut. W. Montgomery, 1st West India Regiment. The troops proceeded to Waterloo in boats, and were there joined by the Wellington company of the Sierra Leone militia, and the Hastings company of volunteers. At the same time, H.M. brig _Charybdis_ (Lieut. Crawford) was sent with the York company of volunteers to the mouth of the Ribbie River, with orders for the seamen and marines to ascend the river in boats, co-operate with Lieut.-Colonel Hingston's column, and cut off the retreat of the rebels. Lieut.-Colonel Hingston's force marched from Waterloo on December 18th, and, halting for the night at Bangowilli, about twenty miles from the former village, advanced towards Cobolo next morning at daybreak. The march was unusually fatiguing, and for many miles the troops had to move through rush beds and mangrove swamps, frequently up to the hips in mud and water. On emerging upon the dry ground near Cobolo the report of fire-arms was heard in front, and scouts being thrown forward, it was learned that the Kossoos, which tribe had suffered most from the predatory propensities of the rebels, had taken up arms and were then engaged in attacking Cobolo. The troops at once pushed on, and a few minutes after their arrival on the scene, the Acoos, completely routed, fled in all directions, many being killed and a great number drowned while endeavouring to escape across a neighbouring creek.
