Prince Charles of Lorraine
Field Marshal, Governor-General of the Austrian Netherlands
"In war, as in hunting, the quarry does not always behave as planned."
Biography
Maria Theresa's brother-in-law (husband of her sister Maria Anna) and her principal military commander for much of the war, Charles of Lorraine was a loyal, courageous, and ultimately outclassed general. He was defeated by Frederick at Chotusitz, Hohenfriedberg, and Soor, and by Saxe at Rocoux. Maria Theresa never lost faith in him — their bond was familial and political — though her army paid a heavy price for her loyalty. He later served as Governor-General of the Austrian Netherlands and became a competent peacetime administrator.

Key Battles
Battle of Chotusitz
Prussia / France / Bavaria victoryMay 17, 1742 · 12,000 total casualties
Chotusitz forced Austria to sign the Treaty of Breslau, ceding Silesia — one of the wealthiest Habsburg provinces — to Prussia. It ended the First Silesian War and established Frederick as a serious commander.
Battle of Dettingen
Habsburg Austria victoryJune 27, 1743 · 8,000 total casualties
Dettingen was a major propaganda victory for Britain and Austria, demonstrating the Pragmatic Alliance's fighting capacity. George II's personal courage, however accidental, became legendary. France declared formal war on Britain the following year.
Battle of Hohenfriedberg
Prussia / France / Bavaria victoryJune 4, 1745 · 15,000 total casualties
Hohenfriedberg is widely considered Frederick's masterpiece of offensive surprise. Executed flawlessly before the enemy could react, it demonstrated the decisive potential of speed, discipline, and night marching that would define Frederician warfare. Austria lost 9,000 prisoners alone.
Battle of Soor
Prussia / France / Bavaria victorySeptember 30, 1745 · 10,000 total casualties
Soor demonstrated that Frederick could win even when surprised — a personal reputation milestone as important as any tactical lesson. His ability to read a collapsing situation and improvise was on full display. Combined with Hohenfriedberg, it ended any Austrian hope of retaking Silesia by force.
Battle of Rocoux
Prussia / France / Bavaria victoryOctober 11, 1746 · 10,000 total casualties
Rocoux extended French control across most of the Austrian Netherlands and confirmed Saxe's dominance of the western theater. Despite Frederick's exit from the war, France continued to accumulate territorial leverage for the eventual peace negotiations.
