We had not been much more than twenty-four hours on board, when the captain, who had been away, returned at midnight; and, at this unusual hour, ordered all the boats, manned and armed, to be piped away immediately. We were informed that the river Sakarron was again our destination; and at four o'clock in the morning we started, with fourteen days' provisions, and armed to the teeth, to join the Dido's boats at the mouth of the river Morotabis, from thence to be towed with them by the steamer to our destination. The cause of this new expedition was the intelligence that the Arab chief, Serib Saib, who had escaped during the late conflict, had returned to the Sakarron to collect together and re-organize his piratical subjects. We soon arrived at the same spot which we had before visited when the town had been burnt down; but the expedition proved to be one of little interest. Notwithstanding his threats, Serib Saib's confidence gave way at the approach of our force, and he made a precipitate retreat up the river, accompanied by four or five hundred of his warriors. Nevertheless, we continued to force our way up the river, with the expectation that, when fairly at bay, he would make a stand. Our advance was made known to the enemy by fires lighted on the different hills abreast of the boats. This speedy mode of communication is adopted by all the natives in this part of the world. Determined not to abandon the pursuit while a chance remained, we followed the redoubtable Serib Saib for eighty miles up the river, which in some parts was too narrow for our boats' crews to make use of their oars; but all obstacles were overcome in the ardour of the chase. To impede our progress, large trees had been felled so as to fall across the river where it was narrow; but these were removed, and we forced our way on. At last the river, as we approached the source, became little wider than a ditch, the barges grounded, and could proceed no farther; the gigs only could float, and we continued, till, after forty-eight hours of severe labour, we found ourselves at the head of the river; and we also discovered that Serib Saib had escaped, having with his whole force landed, and made his way through the jungle into the interior, leaving at our disposal the forty war canoes which had carried him and his men. To follow him was impossible; so we were obliged to content ourselves with the capture of the war canoes, which were all that we had to show for our exertions. Disappointed, and hungry withal, we were not sorry to find ourselves once more with our heads down the river.
