276 LAW AND FREEDOM IN HISTORY and Chao had opportunities that were not open to either Wei or Han for extending her territory and improving her military technique, thanks to her geographical situation on the border between the Sinic World and the Great Eurasian Steppe.1 By contrast, Wei had for her western neighbour not the Eurasian Nomad World but the potentially more formidable Sinic anti-Nomad march-state of Ts'in; and Wei's territory was not only smaller in the aggregate than Chao's; it was also divided into three geographically discontinuous fragments, one of which lay on the farther side of Chao's territory, and another on the farther side of Han's, while Han's metropolitan territory, which lay south of the Yellow River, was similarly insulated by both the territory of Wei and the remnant of the imperial patrimony of Chou from a detached province, north of the river, which was wedged in between the territories of Wei and Chao.2 This awkward geographical distribution of the former domain of Tsin condemned Wei to find herself perpetually at war with her two fellow successor-states in addition to the wars with other neigh- bours which she brought upon herself by her aggressive policy of expansion. The general war (gerebatur 419-370 B.C.) with which this cycle opened consisted of a series of efforts on Wei's part to dominate her neighbours.3 Wei's first move was to take advantage of the domestic troubles, com- mon to all states in the Sinic World of the day, by which Wei's western neighbour Ts'in was paralysed during the years 415-384 B.C.4 In the course of the years 419-409 B.C.3 Wei reconquered from Ts'in a strategi- cally important belt of territory inside the great loop of the Upper Yellow River which had been part of the original domain of Wei's parent state Tsui but had been conquered from Tsin by Ts'in during the pre- Confucian paroxysm of the Sinic Time of Troubles. This reconquest by Wei of 'the Country west of the River' (Ho-si) in 419-409 B.C. was fol- lowed up by a temporarily effective subjugation of Han; but in 386 B.C. Chao succeeded, with Ts'i's help, in resisting Wei's efforts to complete the reunification of Tsui's former domain by subjugating Chao like- wise; and, though Wei inflicted defeats on Ts'i in 384,380, and 378 B.C., and on Ch'u in. 371 B.C., her bid for oecumenical supremacy was frus- trated in 370 B.C. by the combined forces of Chao and Han after Han had doubled her area and resources in 375 B.C. by annexing her neighbour on the west, the state of Cheng.6 . This negative outcome of the General War of 419-370 B.C. was con- firmed by the outcome of the supplementary wars of 354-340 B.C.7 This bout of warfare opened, significantly, with a campaign in which Wei lost to Ts'in part of the reconquered territory 'west of the River'. This reverse was the signal for a general attack on Wei; and, though Wei staved off her now inevitable fate by winning repeated victories against See Franke, op, cit., vol. i, pp. 180-1.
