Johann Tserclaes, Count of Tilly in the context of "Battle of Lutter"

The Battle of White Mountain (Czech: Bitva na Bílé hoře; German: Schlacht am Weißen Berg) was fought on 8 November 1620 in the early stages of the Thirty Years' War. An army of 21,000 Bohemians and mercenaries under Christian of Anhalt was defeated by 23,000 men of the combined armies of Ferdinand II, Holy Roman Emperor, led by Charles Bonaventure de Longueval, Count of Bucquoy, and the German Catholic League led by Johann Tserclaes, later Count of Tilly, at Bílá Hora ("White Mountain") near Prague. Imperial forces entered Prague on 9 November and King Frederick I of Bohemia fled into Silesia.

The Battle of Wimpfen took place during the Palatinate campaign period of the Thirty Years' War on 6 May 1622 near Wimpfen.

The combined forces of the Catholic League and the Spanish Empire under Marshal Tilly and Gonzalo de Córdoba defeated the Protestant forces of Georg Friedrich, Margrave of Baden.

The Battle of Stadtlohn was fought on 6 August 1623 between the armies of the Electoral Palatinate and of the Catholic League during the Thirty Years' War. The League's forces were led by Johann Tserclaes, Count of Tilly, the Protestants by Christian of Brunswick. The battle resulted in a resounding Catholic victory that largely ended the military resistance of the Palatinate forces and thus marked the end of the first phase of the Thirty Years' War.

The Battle of Breitenfeld took place during the Thirty Years' War on 17 September 1631 near Breitenfeld, Leipzig, in modern Saxony. A combined Swedish-Saxon army led by Gustavus Adolphus and John George I, Elector of Saxony defeated an Imperial-Catholic League Army under Johann Tserclaes, Count of Tilly.

Swedish intervention in the Thirty Years' War began in June 1630 when nearly 18,000 troops under Gustavus Adolphus landed in Pomerania, financed by French subsidies. In early 1631, Tilly invaded Saxony after John George I made an alliance with Gustavus Adolphus. The combined Swedish-Saxon force of around 40,150 marched on Leipzig where Tilly's army of 31,400 was based.

The Battle of Rain took place on 15 April 1632 near Rain in Bavaria during the Thirty Years' War. A Swedish army under Gustavus Adolphus of Sweden defeated a Catholic League force led by Johann Tserclaes, Count of Tilly, who later died of wounds received in the battle.

Outnumbered and with many inexperienced troops, Tilly built defensive works along the River Lech, centred on the town of Rain, hoping to delay Gustavus long enough for Imperial reinforcements under Albrecht von Wallenstein to reach him. The Swedes spent 14 April bombarding the defences, then crossed the river the next day, inflicting nearly 3,000 casualties, including Tilly. On 16 April, Maximilian of Bavaria ordered a retreat, abandoning his supplies and guns.
