 Instead of a quick campaign the siege dragged on for 70 days and gave Vyhovsky the much-needed time to prepare for the battle with the Russian army.The hetman not only managed to organize his own troops, but secured support of his allies — the Crimean Tatars and the Poles.By agreement with the Tatars, the Khan Mehmed IV Giray, at the head of his 30,000-strong army, made his way towards Konotop in early summer of 1659, as did the 4000-man Polish detachment with the support of Serbian, Moldavian and German mercenaries.
