At that period the horde was so torn up with inward dissensions that Vasili had not for some years paid tribute to the khan and regarded himself as independent; but in 1408 an unexpected attack was made on Moscow by the Tatar prince Edigei, who like Mamai, without being khan himself, made those who bore the name of khan obey him. Vasili Dmitrievitch being off his guard and thinking that the horde had become weakened, did not take early measures against his wily adversary, who deceived him by his hypocrisy and pretended good-will. Like his father he escaped to Kostroma, but provided better than his father for the defence of Moscow by confiding it to his brave uncle, Prince Vladimir Andreevitch. The inhabitants themselves burned their faubourg, and Edigei could not take the Kremlin, but the horde laid waste many Russian towns and villages. Moscow now learned that although the horde had no longer the power to hold Russia in servitude, yet it might still make itself terrible by its sudden incursions, devastations, and capture of the inhabitants. Shortly thereafter, in 1412, Vasili went to the horde to do homage to the new khan Djelalledin, brought him tribute, and made presents to the Tatar grandees, so that the khan confirmed the grand principality to the prince of Moscow, although he had previously intended to bestow it upon the exiled prince of Nijni-Novgorod. The power of the khans over Russia was now only held by a thread; but for some time yet the Moscow princes could take advantage of it in order to strengthen their own authority over Russia and to shelter their inclinations under the shadow of its ancient might. Meanwhile they took measures of defence against the Tatar invasions, which might be all the more annoying because they were directed from various sides and from various fragments of the crumbling horde. In the west the Lithuanian power, which had sprung up under Gedimin, and grown great under Olgerd, had attained to its utmost limits under Vitovt.
