The position of Mr. Lee at Lingga was fairly safe. He had been for a short time coadjutor with Brereton at Sekrang; at Lingga he had plenty of Malays, and only friendly Dayaks, the Balaus, about him. But Mr. Brereton was in a more dangerous position, a single Englishman among many thousand natives but partially reclaimed in hardly five years, and all passionately attached to their ancestral custom of head-hunting. It is true he had about him a number of Malays, and on an emergency might call in the assistance of those Dayaks of the Sekrang tribe who professed allegiance, but many of these were waverers, and on a few only could any reliance be placed. Early in 1853, reports reached Brereton that Rentap, at the head of a war party, was on his way down the river to attack his fort, and force an opening to the sea, so that again he might pursue his piratical expeditions along the coast; and Brereton sent a message to Lee at Lingga to come to his assistance. The request was at once complied with, and, thinking the case urgent, Lee hurried up the river with a scratch party, insufficiently armed; but he left orders that a large force was to follow with all possible speed. On reaching Sekrang, Lee learned that the force under Rentap was approaching, and he strongly urged Brereton to stand solely on the defensive, and not to attack the enemy till his auxiliaries had arrived. Brereton, however, had built a small stockade a few miles above Sekrang fort, and to this he insisted on going, and was accompanied by Lee. On the morning after reaching it, a few boats of the Sekrang pirates were seen descending the river and approaching the stockade. A gun was fired to signal them to desist, but as this was disregarded, a charge of grape was poured into them, throwing them apparently into confusion. Unfortunately, the Malays in the fort were not to be restrained, and Brereton was for at once dashing forth to attack the enemy in the open on the river. Lee saw the injudiciousness of such a proceeding. He was convinced that the two prahus had been sent forward tentatively, and that the main body of the enemy was concealed behind the point of land farther up. He expostulated with Brereton, who taunted him with a lack of courage, and then left the fort with his Malays, and in their boats they ran in upon the main fleet that was lurking in an upper reach, and which now swung down, assisted by the ebb-tide, on Brereton's light prahus. Lee, nettled at the taunt, and seeing the peril in which his friend and fellow-officer had so inconsiderately placed himself, at once left the fort and hastened to his assistance.
