News of the disastrous defeat of Charles XII at the hands of Peter I and his army at the battle of Poltava in Ukraine, on 28 June 1709, spread across the Swedish empire throughout that summer of 1709. Charles XII managed to escape across the border to the Ottoman Empire, accompanied by roughly 1,000 men, but the remnants of his army surrendered at the village of Perevolochna near the Dnieper river. The defeats at Poltava and Perevolochna resulted in the deaths of 7,000 Swedish soldiers and the capture of 23,000 soldiers and non-combatants. With the Swedish main army destroyed, Denmark and Saxony returned to the war, forming a new coalition against the Swedish empire. Saxon troops entered Poland to recapture the royal crown of Augustus II, whilst Danish-Norwegian troops under Frederick IV invaded Scania and Bohuslän.
