Q: Question: When did the person who von Blumenthal served under in the First Schleswig War first achieve their rank? Passage:Brought up on his grandfather's estate at Reddentin, where his uncle Gustav von Below was founding what would become the Pentecostal movement, von Blumenthal was educated at the military schools of Culm and Berlin. He entered the Guards as 2nd lieutenant in 1827. He studied at the Berlin General War School (later called the Prussian Military Academy). After serving in the Rhine Province, he joined the topographical division of the general staff in 1846. As lieutenant of the 31st foot, he took part in 1848 in the suppression of the Berlin riots, and in 1849 was promoted captain on the general staff. The same year he served on the staff of General Eduard von Bonin in the First Schleswig War, and so distinguished himself, particularly at Fredericia, that he was appointed chief of the staff of the Schleswig-Holstein army, when the previous chief of staff, Captain von Delius, was killed.
