Facing growing uncertainty in the wake of the death of General Johan Banér and mutinous troops following a year of inaction and failure, the Swedes needed to do something to ensure Guelph loyalty and prove to other German Protestant allies that they were still a reliable partner.
Hearing word of the Swedish advance, an Imperial army under Archduke Leopold Wilhelm of Austria and Ottavio Piccolomini raced to meet them.
The Swedes under Carl Gustaf Wrangel and their Bernardine allies led by French general Jean-Baptiste Budes, Comte de Guébriant joined Klitzing's troops on 28 June, and the Imperial army arrived just two hours later.
The Bavarians took heavy casualties storming the woods but finally succeeded in taking the redoubt from the "Old Blue," only to be driven back by a cavalry counterattack dispatched by Guébriant from the main camp.
At this point, Leopold Wilhelm decided to withdraw, having taken around 3,000 casualties in total, although the Swedes had also paid a heavy price for their victory, having lost 2,000 men, with the heaviest toll coming out of the most experienced and veteran troops of the "Old Blue" regiment.
