In 1238, some nineteen years after their initial assault on Persia, Mongol forces began their conquest of Russia. Source 11.4 offers a Russian commentary on those events, drawn from The Chronicle of Novgorod, one of the major sources for the history of early Russia.
The Chronicle of Novgorod
1238
That same year [1238] foreigners called Tartars [Mongols] came in countless numbers, like locusts, into the land of Ryazan, and on first coming they halted at the river Nukhla, and took it, and halted in camp there. And thence they sent their emissaries to the Knyazes [princes] of Ryazan, a sorceress and two men with her, demanding from them one-
… The pagan and godless Tartars, then, having taken Ryazan, went to Volodimir…. And when the lawless ones had already come near and set up battering rams, and took the town and fired it on Friday …, the Knyaz and Knyaginya and Vladyka, seeing that the town was on fire and that the people were already perishing, some by fire and others by the sword, took refuge in the Church of the Holy Mother of God and shut themselves in the Sacristy. The pagans breaking down the doors, piled up wood and set fire to the sacred church; and slew all, thus they perished, giving up their souls to God…. And Rostov and Suzhdal went each its own way. And the accursed ones having come thence took Moscow, Pereyaslavi, Yurev, Dmitrov, Volok, and Tver; there also they killed the son of Yaroslav. And thence the lawless ones came and invested Torzhok on the festival of the first Sunday in Lent. They fenced it all round with a fence as they had taken other towns, and here the accursed ones fought with battering rams for two weeks. And the people in the town were exhausted and from Novgorod there was no help for them; but already every man began to be in perplexity and terror. And so the pagans took the town, and slew all from the male sex even to the female, all the priests and the monks, and all stripped and reviled gave up their souls to the Lord in a bitter and a wretched death, on March 5 … Wednesday in Easter week.
