There is reason to believe that Galdan thought that he might derive some advantage from the complications with Russia, for his military movements were hastened when he heard that the two powers were embroiled on the Amour, and he proclaimed his intention of invading the Khalka region, because some of their people had murdered his kinsmen.
Kanghi showed that he was resolved not to let the terms, to which Galdan had subscribed, become a dead letter. He summoned a great assemblage of the Khalka tribes on the plain of Dolonor the Seven Springs near Changtu and he attended it in person, bestowing gifts and titles with a lavish hand.
But he refused to make any tender of allegiance, or to subscribe himself as a Chinese vassal. The dissensions among the Khalka princes assisted the development of Galdan's ambition, and added to the anxiety of the Chinese ruler.
When the surrender of the Khalka princes became known the Eleuth chiefs held a grand assembly or kuriltai, and at this it was finally, and, indeed, ostentatiously, decided not to yield Kanghi his demands. Important as this decision was, it derived increased weight from the character of the man who was mainly instrumental in inducing the Eleuths to take it.
Kanghi determined to establish friendly relations with this clan, and by the dispatch of friendly letters and costly presents lie succeeded in inducing the Khalka chiefs to enter into formal alliance with himself, and to conclude a treaty of amity with China, which, be it noted, they faithfully observed.
The Russians had built a fort at Albazin, on the upper course of that river, and the Chinese army located in the Khalka country, considering its proximity a menace to their own security, attacked it in overwhelming force. Albazin was taken, and those of the garrison who fell into the hands of the Chinese were carried off to Pekin, where their descendants still reside as a distinct Russian colony.
Although their military power was slight, the name of the Khalka princes stood high among the Mongol tribes, and they exercised an influence far in excess of their numbers or capacity as a fighting force.
