This was a mad and badly-concerted effort to carry through the disorganised plot. It was a plot not only to overthrow the Sarawak Government and murder all the English, but to massacre the Dutch in Western Borneo as well. By industriously spreading false reports, Sherip Masahor prepared the way for a rising of the natives against their English and Dutch rulers, knowing that if successful at one point it would become general. He was well aware how easy it would be to impose upon the ignorant and sheepish people along the coast, and his bold project was to despatch thither a specious and clever Bruni rogue, a runaway of rank from Bruni, named Tunjang, who was to personate the Pangiran Temanggong, the Prime Minister of Bruni, and no less a personage than the late Sultan's son, and the heir to the throne, who had now come from Bruni to exterminate all Europeans. He was to join the Bandar Kasim at Sadong, and advance up that river, raising the people to revolt during his progress, and to follow him. He was to cross over into Netherlands Borneo, where he would find many disaffected against their rulers ready to rally around him, and then proceed down the Kapuas and attack Pontianak, whither the Datu Haji was to proceed from Singapore to organise a second branch of the conspiracy, and to be ready to assist him from within when he appeared off that place. They were then to return and attack Kuching from the interior, whilst the Sherip made a simultaneous attack from the sea. The relation of events which followed we take from the Tuan Muda's narrative[246] and from official records. Early in January, Pangiran Matusin brought the Tuan Muda a letter sent him by the impostor, Tunjang, purporting to be from the Pangiran Temanggong, ordering him to proceed to Sadong and there to join this prince, who was waiting for a numerous force, which was to number many thousands. The Pangiran, the bearers of the letter had told him, was exacting and authoritative, and his orders were being readily obeyed by the people. Matusin supposed that the Temanggong had really come. The letter was a clever forgery executed by the Sherip together with others, which were subsequently sent to the datus and chiefs calling upon them to assist in exterminating all Europeans. The Tuan Muda saw in this a dangerous plot, and the hand of an impostor, and this was the view taken by the members of council. At once strong parties were despatched to cut off the evil-doer, whoever he was, and who, false as he might be, was capable of doing incalculable harm amongst the simple-minded people up-country, and had therefore to be dealt with promptly.
