Next, Tilly turned west and marched through
Germany, but was defeated at the
Battle of Mingolsheim on 27 April 1622. He then joined with the Spanish general Duke
Gonzalo Fernández de Córdoba – not to be confused with the famous Spanish general of the same name from the Italian Wars in Italy at the end of the 15th century – and was victorious at the
Battle of Wimpfen against
George Fredrick,
Margrave of Baden-Durlach on 6 May; this victory occurred after the enemies' ammunition
tumbril was hit by cannon fire and exploded. He was successful again at the
Battle of Höchst on 20 June and was made a
count (
Graf in
German) for this victory. These three battles in two months allowed him to capture the city of
Heidelberg following an eleven-week siege on 19 September.
Christian the Younger of Brunswick, whom he had already defeated at Höchst, raised another army, but again lost to him at the
Battle of Stadtlohn, where 13,000 out of his army of 15,000 were lost, including fifty of his high-ranking officers. Together with the complete surrender of Bohemia in 1623, this ended virtually all resistance in Germany. This caused King
Christian IV of Denmark to enter the
Thirty Years' War in 1625 to protect
Protestantism, and also in a bid to make himself the primary leader of
Northern Europe. Count Tilly besieged and captured
Münden on 30 May 1626, whereupon local and refugee Protestant ministers were thrown into the river Werra, but could not lay a siege to
Kassel. Tilly fought the Danes at the
Battle of Lutter on 26–27 August 1626, in which his highly disciplined infantry charged the enemy lines four times, breaking through. This led him to win decisively, destroying more than half the fleeing Danish army, which was uncharacteristic of the warfare of the time. Denmark was forced to sue for peace at the
Treaty of Lübeck. This disrupted the balance of power in Europe resulting in
Swedish involvement in 1630 under their redoubtable leader, the brilliant King and field general
Gustavus Adolphus of Sweden, who had been trying to dominate the
Baltic for the previous ten years in wars with
Poland, then a continental
power of note. ==Sack of Magdeburg==
