This map from Beskrovni's Atlas of Russian
military history shows the routes of the Muscovite armies from Moscow to Kazan.
One section was diverted temporarily south by the incursion of the Crimean
Tatars around Tula and Kashira. We see that the lead or advance polk, the great
or main polk and the right arm polk traveled by the southern route across
country through Ryazan, while the left arm polk and the Tsar's peresonal
druzhina went via Vladimir and Murom. They reached the Volga at the fortress
built on an island at Sviyazhsk where they met supplies and artillery brought
down the river by barge.
