Battle of Soor
# Battle of Soor

The Battle of Soor (30 September 1745) was a battle between Frederick the Great's Prussian army and an Austro-Saxon army led by Prince Charles Alexander of Lorraine during the Second Silesian War (part of the War of the Austrian Succession). The battle occurred in the vicinity of Soor, also known as Hajnice, in the modern day Czech Republic. The battle started with a failed Austrian surprise attack on the outnumbered Prussians. Despite initial setbacks the Prussian army managed to defeat the Austrians, due to an unexpected attack from a reserve regiment that refused to follow Frederick's orders.

## Background

Three months after the battle of Hohenfriedberg, Frederick laid the "Camp of Staudenz", initially planning to return to Berlin, in order to inspect the building work on his new palace of Sans Souci. Having stripped off many detachments during his march through Bohemia, Frederick's numbers had been reduced to 22,500 men. Prince Charles then discovered that Frederick had failed to occupy the Graner-Koppe, a hill north of Burkersdorf (Střítež, Trutnov District, modern day Czech Republic) that dominated the landscape to the east and south. On 29 September, Charles attempted to flank the Prussian camp from the Königreich-Wald hills, and the following morning the Austrians took positions on the crucial Graner-Koppe hill. The 40,200-strong Austrian army intended to destroy the Prussians in a surprise attack.

## Battle

Prussian scouts soon detected the Austrian presence, and drummers and trumpeters sounded the general alarm as Prussians began preparing for battle. Austrian artillery proceeded to fire on the Prussian encampment, while the Prussian army marched into battle.

Frederick ordered the cavalry to charge up the valley to the side of the hill in order to encircle the enemy. During the maneuver the cavalry came under artillery fire, suffering heavy casualties. Despite the initial setback the vanguard regiments of the gendarmes and General Buddenbrock's cuirassiers managed to surprise the Austrian cavalry forcing it to flee. Coming under musket fire the Prussian cavalry withdrew to the rear of the force.

By the time of the cavalry retreat, Prussian grenadiers and the Anhalt infantry regiment began engaging the Austrian troops positioned on the hill. An Austrian counterattack, supported by artillery fire, dealt significant damage to the Prussian infantry causing it to fall back. The Prussians then launched a second assault consisting of Geist Grenadiers, Blanckensee, La Motte and other battle hardened regiments. The unwillingness of the Austrian artillery to risk firing at its own troops contributed to the fall of the summit.

A number of Prussian regiments positioned south of Burkersdorf ignored orders to remain in the area and attempted to capture Burkersdorf. A bayonet charge led by Prince Ferdinand of Brunswick seized an Austrian battery, and the surprise attack led to the collapse of the Austrian line. Despite the lack of an organised pursuit many Austrian infantrymen were captured by the Prussian cavalry regiments.

A total of 856 Prussians were killed, while the injured or missing amounted to 3,055. Austrian and Saxon troops suffered 7,444 dead, injured or missing.
