Holy Roman Empire The Battle of Höchst (20 June 1622) was fought between a Catholic League army led by Johan Tzerclaes, Count of Tilly and a Protestant army commanded by Christian the Younger, Duke of Brunswick-Lüneburg, close to the town of Höchst, today a suburb of the city of Frankfurt am Main.

In early May, however, Tilly won a decisive engagement with Georg Friedrich, Margrave of Baden-Durlach at the Battle of Wimpfen, which dispersed or killed approximately 3/4 of Georg Friederich's army, leaving only Christian of Brunswick and Ernst von Mansfeld to command in the coming battle.

At the same time the Catholic troops approached in forced marches from Würzburg with 20,000 infantrymen, 6,000 cavalrymen, and 18 guns.

However, Christian succeeded in escaping with 3,000 cavalrymen, 8,000 infantrymen, and his war chest, eventually uniting with Mansfeld's army.

With this news, the token English forces under Sir Horace Vere evacuated Mannheim, which fell on 2 November, and moved to the fortress of Frankenthal, which served as a final outpost for Protestant resistance in this area.

Duke Maximillian now controlled half of the Lower Palatinate and installed Heinrich von Metternich as governor.
