The grand duke continued his father's policy toward Lithuania. When Alexander died, he tried to become Grand Duke of Wilna, but the King of Poland was too quick for him. War broke out, but neither gained any important advantage, and in 1509 a _perpetual peace_ was concluded wherein Vassili renounced all claims upon Kief and Smolensk. The "perpetual peace" lasted three years. Vassili then went to the other extreme, by declaring that "as long as his horse was in marching condition and his sword cut sharp, there should be neither peace nor truce with Lithuania." In 1514, the Russian army besieged and took Smolensk, but in the same year they were badly defeated in the battle of Orcha. The two grand dukes tried to involve as many allies as they could. The Khan of the Crimea, the useful friend of Vassili's father, had become the son's enemy; Vassili offset him by an alliance with the Khan of Astrakhan. When Sigismund tried to secure the help of Sweden, Vassili sought that of Denmark; and when his enemy set the Dnieper Cossacks at him, the grand duke induced the Teutonic Order to invade Poland. After Sigismund was defeated at Smolensk, the Emperor of Germany and the Pope offered to mediate; the latter advised Vassili to let Lithuania alone, and to turn his attention toward Constantinople. Negotiations commenced in 1520, but it was six years later before a truce was (p. 109) concluded. On this occasion Vassili made a speech in which he praised Emperor Charles V, and Pope Clement VII,--but Lithuania lost Smolensk. It was during this war that the partition of Poland was first mentioned. Vassili did not neglect the east, even while engaged in the west. Kazan had expelled the nephew of the Khan of the Crimea whom Ivan III had appointed, and elected a Khan hostile to Russia. Two expeditions were sent against the city but nothing was effected. When this khan died, Vassili succeeded in installing a friendly prince, but he was overthrown and a relative of the Khan of the Crimea took his place. He prepared a great invasion of Russia in 1521, and did gain a decided victory on the Oka, after which he ravaged the territory of the grand duke. Vassili was compelled to humble himself before the khan, in order to save Moscow; he made him presents and in the treaty signed by him, called himself the khan's tributary. When the khan withdrew, he was attacked in Riazan and the treaty was taken away from him. The invasion was, however, a calamity for the grand dukedom, which was devastated by fire, and a host of women and children were carried off, to be sold as slaves at Astrakhan and Kaffa. The following year Vassili collected a large army on the Oka and challenged the Khan of the Crimea to come and give battle. The offer was declined with the remark that he knew the way into Russia, and that he was not in the habit of consulting his enemies as to when and where he was to fight.
