decisions were made. The quarrel with his brothers was settled and their troops began moving toward the Oka. The state treasury and royal family were moved north to Beloozero and some cities were evacuated. Vasily Nozdrovaty and the exiled Crimean khan Nur Devlet were sent east down the Oka and Volga to attack Akhmed in the rear. Meanwhile, Akhmed had moved northward between the upper Don and Oka and at an uncertain date made camp at Vorotynsk just south of the Ugra-Oka junction on the west side of the Oka. Here he waited for Casimir, who never came. Casimir was tied down fighting the Crimeans in Podolia, but he may have had other reasons. On 3 October Ivan moved to Kremenskoye (then called 'Kremenets' to watch the front. Nesin (2015) gives the Russian front as 60 versts (kilometers), but does not specify its start and end points. On 6–8 October Akhmed moved his troops up to the Ugra. Fighting began at one o'clock on the eighth and continued for almost four days. All attempts to cross the river failed, largely because of Russian firearms and because the river was wide enough to make Tatar arrows ineffective. The battlefield extended five kilometers along the Ugra from its mouth westward. Akhmed withdrew two versts (kilometers) south to a place called Luza (location?). He then tried to secretly move his troops to a place called 'Opakhov', but his movement was detected and the crossing blocked. Ivan began negotiations with Akhmed which led nowhere but gave Ivan time to bring up more troops. Both sides spent the next month watching each other across the river, this being the standoff proper. It was getting late in the season and both sides knew that once the river froze solid it would no longer be a barrier. Akhmed could concentrate his forces and break the thin Russian line at any point. Ivan's best plan was to pull back and concentrate his force. On 26 October Ivan began moving troops from the Ugra northeast to Kremenskoye and then east to Borovsk. Here he had a good defensive position to protect Moscow and could strike in any direction if Akhmed chose to advance. Ahmad expected Casimir IV Jagiellon to join him with Lithuanian reinforcements, but as Casimir faced a revolt at home, he never showed up. Instead of advancing, on 8 November Akhmed began to withdraw. News of the
