Karl Konstantin Albrecht Leonhard Graf von Blumenthal (30 July 1810 – 21 December 1900) was an officer of the Prussian Army and field marshal of the Imperial German Army, chiefly remembered for his decisive intervention at the Battle of Königgrätz in 1866, his victories at Wörth and Weißenburg, and above all his refusal to bombard Paris in 1870 during the siege, of which he was in command. Early life Born in Schwedt, Brandenburg, on 30 July 1810, Leonhard was the son of Ludwig Albrecht von Blumenthal (1774–1813) and his wife Friederike Charlotte Dorothea von Below (1783–1853). Ludwig was a captain in the Brandenburg Dragoon Regiment who was wounded in the Battle of Dennewitz, and later died from his injuries at Potsdam. Leonhard had a younger brother, Karl (1811-1903), who would later serve as a major-general in the army. Leonhard was brought up on his grandfather's estate at Reddentin, where his uncle Gustav von Below was founding what would become the Pentecostal movement. He was educated at the military schools of Culm and Berlin, entering the Guards as a 2nd lieutenant in 1827, and studied at the Berlin General War School (later called the Prussian Military Academy). Military career After serving in the Rhine Province, von Blumenthal 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. In 1850, von Blumenthal was general staff officer of the mobile division under Tietzen in Hesse-Kassel. He was sent on a mission to England in that year (4th class of Red Eagle), and on several subsequent occasions. Having attained the rank of lieutenant-colonel, he was appointed personal adjutant to Prince Frederick Charles in 1859. In 1860 he became colonel of the 31st, and later of the 71st, regiment. He was chief of the staff of the III Corps when, on the outbreak of the Second Schleswig War of 1864, he was nominated chief of the general staff of the army against Denmark, and displayed so much ability, particularly
