During the ensuing night, H.M.S. _Arrogant_, Commodore Edmonstone, arrived in the Gambia River, and early next morning the _Dover_ brought the Commodore, with a naval brigade of seamen and marines, up to Swarra Cunda Creek. This unlooked-for accession of strength determined Lieutenant-Colonel Murray to advance into the interior, and strike a blow that would bring the war to a conclusion. Cattle were obtained for the field-guns, which were then landed, and about noon on the 18th, the force marched inland, four companies of the 1st West India Regiment forming the right division, four of the 2nd West India Regiment the left division, and two of the 1st the reserve, with the guns on the flanks. The country through which the advance was made was a level sandy plain, covered with tall grass, and dotted here and there with clumps of baobab and dwarf palm. Occasionally a few clearings for the cultivation of the ground nut were met, but as a rule the march was made through grass more than waist high. The enemy showed in force, but made no serious opposition to the advance; and, though large bodies of cavalry were observed hanging about the flanks and rear, they showed no disposition to close, and the towns of Kinty-Cunda and Sabba were destroyed without loss on our side, and very small loss, if any, on the part of the enemy. The 19th and 20th were devoted to changing the camping ground, and arranging a plan of campaign against Indear, the king's town, in which the shipping might be used as a base; but, on the afternoon of the latter day, a slave-girl, who came into the camp to claim British protection, reported that the king's warriors, having been largely reinforced, had come down from Indear, and had erected a stockade on the ruins of Sabba. Although it did not suit Lieut.-Colonel Murray's plans to return to Sabba, he did not consider it advisable to leave this unexpected challenge unanswered; and, on the morning of February 21st, the force again marched for Sabba.
