[2] In the book by Vitaly Penskoi, it is claimed that the Russian tsar complained that only 15,000 people gathered with him on a campaign against Kazan.

At that time, the Crimeans captured several Russian people near Ryazan and learned from them that the tsar had deployed troops on the banks of the Oka.

This came as a surprise to the Crimean Khan, because he hoped that the Russian troops would march on Kazan, and recalling the experience of 1541, he decided to abandon the campaign, but it was impossible to retreat without doing anything, so Devlet I Giray convened a council of princes, at which he was advised to go to Tula, disobey them he could not, because they had recently brought him to power and the Crimean Khan turned his army on Tula[4]On June 21, news came that a small Crimean army appeared near Tula, but they robbed several villages and hastily disappeared.

Upon learning of the approach of Russian troops, the Crimean Khan hastily retreated, abandoning the wagons and a small part of his army.
