FREDERICK II OF PRUSSIA (KNOWN AS FREDERICK THE GREAT) (1712-1786) Letter signed «Federic», in French, addressed to Claude-Louis de Saint-Germain.

Camp of Chlum [near Königgrätz in Silesia, now near Hradec Králové in the Czech Republic], 7 August 1745. 1/3 p. in-4. The Difficult Conquest of Silesia: Frederick the Great had already planned the extension of his kingdom at his accession (1740) and in 1742 conquered Silesia, which had previously been under Austrian rule. Austria twice tried in vain to regain the province (1744-1745 and 1756-1763). The Count of St. Germain (1707-1778), who was later to become Louis XVI’s Minister of War, served Bavaria, Prussia’s ally in the War of the Austrian Succession.
