We were here joined by a large number of the Linga Dyaks, the same force that had joined us the year previous, while up the Sarebus, but unaccompanied by Seriff Jaffer, of whom it was not quite clear that he had not been secretly aiding the pirates. I sent them back with assurances to their chiefs that they should not be molested unless they gave shelter or protection to either Seriff Sahib or Muller. Seriff Sahib, with a considerable body of followers, escaped inland in the direction of the mountains, from the other side of which he would be able to communicate with the river Linga. Macota was obliged to fly up the river toward the Undop, on which the village and residence of Seriff Sahib's brother, Seriff Muller, was situated. Having destroyed every boat and sampan, as well as house or hut, on the 10th, as soon as the tide had risen sufficiently to take us over the shoals, we weighed, in the steamer, for the country of the Sakarran Dyaks, having sent the boats on before with the first of the flood. About fifteen miles above Patusen is the branch of the river called the Undop: up this river I dispatched Lieutenant Turnour, with Mr. Comber, in the Jolly Bachelor, and a division of our native boats, while we proceeded to where the river again branches off to the right and left, as on the tongue of land so formed we understood we should find a strong fort; beside, it was the highest point to which we could attempt to take the steamer. The branch to the left is called the Sakarran; that to the right retains the name of Lupar, inhabited chiefly by Sakarrans. We found the place deserted and the houses empty. Knowing that these people depended almost entirely for protection on the strongly fortified position at Patusen, I did not expect any similar opposition from either Seriff Muller or the desperate bloodthirsty Sakarrans, and consequently divided my force into three division--the one, already mentioned, under Lieutenant Turnour, up the Undop; another, under Mr. D'Aeth, up the Lupar; while Lieutenant Wade, accompanied by Mr. Brooke, ascended the Sakarran. I had not calculated on the disturbed and excited state in which I found the country; and two wounded men having been sent back from the Undop branch with accounts of the pirates, chiefly Malays, who were collected in great numbers, both before and in the rear of our small force; and an attempt having been made to cut off the bearer of this information, Nakoda Bahar, who had had a very narrow escape, and had no idea of taking back an answer unless attended by a European force,--I determined on sending assistance. But I had some difficulty in mustering another crew from the steamer, and was obliged to leave my friend Capt. Scott, with only the idlers, rather critically situated.
