The Battle of Adelsbach is one of the lesser-known episodes from the final phase of the Seven Years War in Europe. It was the first significant clash between Prussians and Austrians in Silesia in 1762 and the only battle in which Frederick the Great lost, despite his superiority over his opponent. The combat took place on 6 July 1762. During its course, the combined Prussian-Russian troops commanded by Frederick II of Prussia and

General Karl Wied endeavoured to defeat the small Austrian corps of General Josef Brentano. The topography of the terrain favoured the Austrians and played a crucial role in the battle, along with the Austrians’ skilful leadership and the courage of their troops, especially those from the Hungarian Bethlen Regiment and the combined grenadier battalion. The Prussians outnumbered their opponents by more than three to one, but thwarted by the Austrians’ dogged defence, they retreated, losing 1,352 soldiers and at least three colours.

Adelsbach 1762 presents the circumstances of the battle in detail, including its course and significance. It examines the leading actors of the battle, the commanders and the soldiers of individual regiments. In addition to studies conducted over the course of three centuries, it utilises previously unpublished source materials from Austrian, German, Czech, and French archives.
