After concluding a treaty with Ivan III, all Russian prisoners of war held by the Khanate were released.
In response to this Ibrahim-khan in winter made a dragoon[clarification needed] to the border areas of the enemy and plundered the environs of Galich Merskoy.
In 1468, Ivan III sent strong garrisons to Nizhniy Novgorod, Murom, Kostroma, Galich and began military action on the territory of Khanate.
This campaign accompanied by extreme violence against ordinary people with the purpose of provoking Kazan into a big war.
The ushkuyniks went by boats to Kama from Vyatka and began robbing the hinterland of the Khanate (deep behind the lines).
