Birth and Early Career

Born in Piedmont, Italy, in 1712, Count Antonio Guasco started his military career with the Russian army. He participated in several campaigns, including the Russo-Turkish War (1735-1739) and the Russo-Swedish War (1741-1743).

Transfer to the Austrian Army

Following the Silesian Wars, Guasco joined the Austrian army. Emperor Franz I assigned him to survey the Moravian and Bohemian borders for defensive planning. At the outbreak of the Seven Years' War, he served as Quartermaster General.

Distinguished Service in the Seven Years' War

Guasco played a pivotal role in the Seven Years' War. He fought with bravery in the Battle of Prague (May 1757), the Battle of Kolin (June 1757), and the Battle of Breslau (November 1757). In recognition of his outstanding performance, he was awarded the prestigious Order of Maria Theresa.

Defense of Erfurt and Saxony

As Commandant of Erfurt in 1759, Guasco attempted to strengthen the city's defenses. However, the negligence of Austrian outposts allowed Prussian partisans to capture the city. Guasco's role in Saxony was more successful. He was instrumental in negotiating the surrender of Dresden. In 1760, when King Frederick the Great besieged Dresden again, Guasco led a reinforcement force of 10,000 men into the city.

Siege of Schweidnitz

Guasco's most renowned feat came in 1762 during the Siege of Schweidnitz. With the assistance of the skilled engineer and artilleryman Griboval, he implemented a rigorous defense. The siege was prolonged until late in the season. However, an explosion in the laboratory of the Jauernik bastion weakened the fortifications, rendering it impossible to repel the assault. Guasco was forced to surrender.

Death and Legacy

Upon surrendering, Guasco was taken prisoner to Königsberg. He succumbed to an apoplectic stroke on March 23, 1763. Historian I. V. von Archenholtz described Guasco as "an excellent commander, renowned for his valor and military expertise." However, Archenholtz also accused him of violating the terms of the capitulation of Prussian forces at Dresden in 1759.
