The blow which broke the power of these confederacies was inflicted in 1849. News came to Sarawak that the pirates had put to sea, marking their course by fearful atrocities. At once Mr. Brooke applied to the English Admiral for assistance, and the steamer Nemesis was despatched to the scene of action. The Rajah joined her with eighteen war-boats, to which were afterwards added eleven hundred Dyaks, in their bangkongs. On the 31st of July, at night, they encountered the great war-fleet of the Sarebus and Sakarran pirates, numbering one hundred and fifty bangkongs, returning home laden with plunder. The pirates found the entrances of the river occupied by their enemies,--the English, Malay, and Dyak forces being placed in three detachments, while the Nemesis was fully prepared to assist whenever the attack should begin. "Then there was a dead silence, broken only by three strokes of a gong, which called the pirates to a council of war. A few minutes afterwards a fearful yell gave notice of their advance, and the fleet approached in two divisions. In the dead of the night there ensued a terrible scene. The pirates fought bravely, but they could not withstand the superior forces of their enemy. Their boats were upset by the paddles of the steamer. They were hemmed in on every side, and five hundred men were killed sword in hand, while twenty-five hundred escaped to the jungles, many of them to perish. The morning light showed a sad spectacle of ruin and defeat. Upwards of eighty prahus and bangkongs were captured, and many more destroyed." The English officers would have gladly saved life; but the pirates would take no quarter, and the prisoners were few. It was a striking fact, that one of the war-boats under Mr. Brooke was manned by some thirty Malays, every one of whom had lost during the year a near relative, killed by these same pirates. The confederacy has never risen from this defeat, and for years the tribes composing it have returned to the labors of peaceful life. Writing twelve months afterwards to a friend, Rajah Brooke says: "Pray keep the 31st of July apart for a special bumper, for during the last year not a single innocent life has been taken by these pirates, nor a single prahu fallen into their hands." Many a victory, famous in story, has accomplished less.
