Charles August, Crown Prince of Sweden
Heir to the Throne of Sweden
Charles August or Carl August (9 July 1768 – 28 May 1810) was a Danish prince. He is best known for serving as Crown Prince of Sweden briefly in 1810, adopted by Charles XIII, before his sudden death from a stroke. Earlier, he had been a general in the Royal Danish Army as well as the Governor-general of Norway. His name before assuming the Swedish title in 1810 was Christian August of Schleswig-Holstein-Sonderburg-Augustenburg, or Christian August of Augustenburg for short.
Family
He was born at Augustenborg Palace in July 1768 as the son of Friedrich Christian I, Duke of Schleswig-Holstein-Sonderburg-Augustenburg (1721–1794) and his wife, Princess Charlotte of Schleswig-Holstein-Sonderburg-Plön (1744–1770). He was a younger brother of Frederik Christian II, Duke of Augustenborg, brother-in-law of Princess Louise Auguste of Denmark and an uncle of Caroline Amalie of Augustenburg, Queen consort of Denmark and Christian August, Duke of Augustenborg. He did not marry.
Career in Denmark and Norway
Christian August studied in Leipzig, and returned from there to Denmark-Norway in 1785. He was appointed lieutenant colonel, and was promoted to colonel in 1787 and major general in 1790. From 1797 he was stationed in Austria, joining the fight against Napoleon.

The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
