Confucius' old friend the ruler of Ts'i was still alive (he reigned fifty-eight years, one of the longest reigns on record in Chinese history), and he had just suffered serious humiliation at the hands of the barbarous King of Wu, to whose heir-apparent he had been obliged to send one of his daughters in marriage. The Protectorate of China was going a-begging for want of a worthy sovereign, and it looked at one time as though Confucius' stern and efficient administration would secure the coveted prize for Lu. The Marquess of Ts'i therefore formed a treacherous plot to assassinate both master and man, and with this end in view sent an envoy to propose a friendly conference. It was on this occasion that Confucius uttered his famous saying (quoted, however, from what "he had heard") that "they who discuss by diplomacy should always have the support of a military backing." A couple of generals accordingly accompanied the party to the trysting-place; and it is presumed that the generals had a force of soldiers with them, even though the indispensable common people be not worth mention in Chinese history. In conformity with practice, an altar or dai's was constructed; wine was offered, and the usual rites were being fulfilled to the utmost, when suddenly a Ts'i officer advanced rapidly and said: "I now propose to introduce some foreign musicians," a band of whom at once entered the arena, with brandished weapons, waving feathers, and noisy yells. Confucius saw through this sinister manoeuvre at once, and, hastily mounting the dais (except, out of respect, the last step), expostulated in the plainest terms. The ruler of Ts'i was so ashamed of his position that he at once sent the dancers away. But a second group of mountebanks were promptly introduced in spite of this check. Confucius was so angry, that he demanded their instant execution under the law (presumably a general imperial law) "providing the punishment of death for those who should excite animosity between princes." Heads and legs soon covered the ground; and Confucius played his other cards so well that he secured, in the sequel, a formal treaty, actually surrendering to Lu certain territories that had unlawfully been held for some years by Ts'i. On the other hand, Lu had to promise to aid Ts'i with 22,500 men in case Ts'i should engage in any "foreign" war--probably alluding to Wu. Two or three years after that stirring event there was civil war in Lu, owing to Confucius having insisted on the "barons" dismantling their private fortresses.
