The origins and course of the fighting over the Ussuri island of Chenpao in March 1969 are as sharply disputed as the island itself. That fighting had broken out on 2 March was announced in a broadcast from Moscow that day and a Soviet Note to Peking of the same date charged that the Chinese had deliberately organized an armed provocation by sending troops across the state boundary line. Soviet frontier guards had been dispatched to warn them off Soviet territory: “The Chinese servicemen let the Soviet frontier guards approach them to a distance of a few metres and then suddenly, without any warning, opened point-blank fire at them.” Simultaneously, other Chinese troops, lying in ambush on the island itself, opened fire at the Soviet frontier guards on the ice. The Chinese, in this version, used machine-guns, mortars and artillery as well as automatic rifles, and about 200 troops. In later Soviet accounts that number was enlarged to 300. The Russians said they lost 31 killed and 14 wounded in the action but that they “expelled the violators from Soviet territory.”
