Q: Question: How many years did the war last where Curtis fought with the City Imperial Volunteers in? Passage 1:Curtis was born at Coddington, Herefordshire in 1872, the youngest of the four children of an Anglican rector. He was educated at Haileybury College and then at New College, Oxford, where he read law. He fought in the Second Boer War with the City Imperial Volunteers and served as secretary to Lord Milner (a position that had also been held by adventure-novelist John Buchan), during which time he dedicated himself to working for a united self-governing South Africa. Following Milner's death in 1925, he became the second leader of Milner's Kindergarten until his own death in 1955. His experience led him to conceptualize his version of a Federal World Government, which became his life work. In pursuit of this goal, he founded (1910) the quarterly Round Table. He was appointed (1912) Beit lecturer in colonial history at the University of Oxford, and a Fellow of All Souls College.

She appeared twice on the Charlie Rose nationally broadcast television interview show.

Passage 3:His own military genius blossomed during the Napoleonic Wars. During the 1805 Campaign, Yermolov served in the rear and advance guards and distinguished himself at Amstetten and Austerlitz. For his actions, he was promoted to colonel on 16July 1806. The following year, he participated in the campaign in Poland, serving in Prince Bagration's advance guard. He distinguished himself commanding an artillery company in numerous rearguard actions during the retreat to Landsberg as well as in the Battle of Eylau. In June 1807, Yermolov commanded horse artillery company in the actions at Guttstadt, Deppen, Heilsberg and Friedland, being awarded the Order of St. George (3rd class, 7 September 1807). He was promoted to major general on 28 March 1808 and was appointed inspector of horse artillery companies. In early 1809, he inspected artillery companies of the Army of the Danube. Although his division took part in the 1809 campaign against Austria, Yermolov commanded the reserves in Volhynia and Podolsk gubernias, where he remained for the next two years. In 1811, he took command of the guard artillery company and in 1812, became the Chief of Staff of the 1st Western Army.
