In the early days of the Seven Years War, known in the British colonies of North America as the French and Indian War, Prussia was surrounded and isolated by its enemies France, Sweden, Saxony, Russia and Austria. Frederick II, King in Prussia’s only major ally was Great Britain. Unfortunately for Frederick, the British war would be conducted in India, the West Indies, the Americas, and especially on the high seas. King George II could offer no military assistance to the Prussians on the European continent. In 1757, the weight of numbers was immediately felt by Frederick and his small army. His initial invasion of Bohemia to knock Austria out of the war failed, the Russians over ran East Prussia, France steamrolled his small German allies to the west, and Austria was marching on Silesia to the south with a massive army from the heart of their empire.
Frederick however had two big advantages: he had interior lines of communication which allowed him to quickly shift his army to face the different threats, and his army was much more highly trained and disciplined than his opponents’. Knowing the French would be an easier target, he first engaged and mauled the French “mob” at the Battle of Rossbach; lest they fall upon him from behind as he moved to face the much larger and better trained Austrian Army. He then turned to face the Austrians.
At the town of Leuthen (Lutyia in modern Poland), Frederick’s 37,000 man force encountered the 80,000 strong army under Prince Charles of Lorraine. What Charles didn’t know was that the rolling hills around Leuthen were the Prussian Army’s primary drill grounds and maneuver training area. Every one of Frederick’s soldiers, officers and units had spent thousands of hours learning and mastering the rigid tactics of the eighteenth century linear battlefield there. And now they were going to fight a battle on the very ground they’d trained on.
On 5 December 1757, the two armies lined up opposite each other. In the early morning mist and fog common to Central Europe, Frederick disengaged from battle before it really even began. Prince Charles was surprised, but nonetheless let the Prussians leave unmolested, confident that Frederick would have to eventually face him. It would happen much sooner than he expected.
Frederick was just feigning retreat and marched south over the familiar terrain around the Austrians’ left flank without getting lost in the fog, all the while screened by the hills. Once south of the Austrians, Frederick’s entire highly trained army did the 37,000 man equivalent of a “Left Flank, March” and rolled up the Austrians from the south while the Austrians were still facing west. Unable to concentrate any sort of mass to the face the attack, the surprised and confused Austrians broke in short order.
The Seven Years War/French and Indian War would eventually become the planet’s first “World War” but because of the Battle of Leuthen, the next five years of that war would be fought on Prussian and British…and American terms.
