Ratu Nkara and his friend Mr. Williams, the United States Consul, Ratu Mara, Tui Levuka, and the Europeans of Ovalau, who had combined to bring him to this pass, styled themselves the "League." Their agreement, as set forth in a letter from Pickering to Williams, afterwards made public, was "to stop all ships of going to Mbau," and to invoke the aid of the first ship-of-war that might arrive. Consul Williams's ill-directed activity in the cause proved the undoing of all the schemes, for he wrote a violent letter to the newspapers in Sydney, urging the destruction of Mbau as the first duty of civilized nations, which, when translated to Thakombau, convinced him that his only chance of salvation lay in conciliating the missionaries. A letter which he received at the same time from King George of Tonga persuaded him that it was high time to embrace Christianity. His defeat at Kamba after so many favourable omens had rudely shaken whatever belief he may have had in the gods of his fathers, and if he now rejected the support of King George and the missionaries he would have had no friends left. He had been profoundly moved by the news of the assassination of Tui Kilakila, the chief of Somosomo, which, the missionaries assured him, was a judgment on him for his opposition to Christianity, and he was moreover suffering from a painful disease of the leg. Cut off as he was from communication with the Europeans who opposed the conversion of Mbau, there was no hostile counsel to neutralize the persuasions of the missionaries. [Pageheader: THAKOMBAU CONVERTED] On April 28, 1854, the momentous decision was made. Assembling his chiefs he read the two letters to them, and announced his decision, reminding them of the prosperity of Tonga since the adoption of Christianity. On the following Sunday he attended service with about three hundred of his chiefs and retainers, all clad in waistcloths, for the missionaries had ordained that the outward sign of conversion should be clothes. As soon as the people had recovered from their astonishment there was a convulsion that nearly cost Thakombau his life. Rewa was still stoutly heathen, and all the malcontents in Mbau flocked to the enemy. The island of Koro also rose. Mbau was now hemmed in, and for the first time since 1835 it was put into a state of defence. But there were traitors within. Yangondamu, Thakombau's cousin, won over by two of the king's brothers who had joined the enemy, had engaged to assassinate him. His house was crowded with young chiefs anxious to pay court to the rising power, while Thakombau sat alone, deserted by all but the missionary and a faithful Tongan. This immediate peril was averted by the dispatch of Yangondamu in command of a force to reduce the Koro rebels, and while he was away a Captain Dunn arrived from America with a cargo of arms, which he insisted upon selling to the Mbauans despite the entreaties of the Europeans.
