Question: How old was the former commander of the 40th Regiment of Foot when MacDowall came to replace him? Passage 1:Becoming editor of La Lanterne in 1882, he founded two years later Le Matin. In December, 1882, he was chosen to represent the Gros-Caillou quarter in the municipal council of Paris, and was reelected in 1884. Dreyfus in this position showed a remarkable aptitude for finance. In October, 1885, he was elected deputy by the department of the Seine, and was reelected, for the Twelfth District, in 1889, in opposition to a Boulangist candidate. A radical, with wide schemes of reform, Dreyfus sat with the Extreme Left. He was appointed a member of the army commission, and also on that of espionage. He fought many duels, one with the Marquis de Morès, the anti-Semite. His publications include: Une Dictature (Le Mans, 1874); Giboyer à Saint-Pélagie (Paris, 1875); L'Evolution des Mondes et des Sociétés (Paris, 1888); Les Traités de Commerce (Tours, 1879); Le Tunnel du Simplon et les Intérêts Français (Paris, 1879); L'Angleterre, son Gouvernement, ses Institutions (Paris, 1881); La Guerre Nécessaire, Réponse d'un Français à M. de Bismarck (Paris, 1890). Dreyfus was also secretary and part founder of La Grande Encyclopédie. He was a member of the Légion d'honneur.
 Passage 2:France–United Kingdom relations are the relations between the governments of the French Republic and the United Kingdom of Great Britain and Northern Ireland (UK). The historical ties between France and the UK, and the countries preceding them, are long and complex, including conquest, wars, and alliances at various points in history. The Roman era saw both areas, except northern England and Scotland, conquered by Rome, whose fortifications exist in both countries to this day, and whose writing system introduced a common alphabet to both areas; however, the language barrier remained. The Norman conquest of England in 1066 decisively shaped English history, as well as the English language. In the medieval period, the countries were often bitter enemies, with both nations' monarchs claiming control over France. Some of the noteworthy conflicts include the Hundred Years' War and the French Revolutionary Wars which were French victories, and the Seven Years' War, Second Hundred Years’ War and Napoleonic Wars, from which Britain emerged victorious.
 Passage 3:MacDowall was appointed Lieutenant-Colonel of the 57th Regiment of Foot in 1791 and served in Flanders in 1793 and after serving as Commander-in-Chief in Ceylon from 1798 to 1804. In 1802, as a Major-General, he was appointed Colonel commandant of a Battalion of the 40th Regiment of Foot in place of Lord Hutchinson. He was appointed Commander-in-Chief of the Madras Army in 1807. He was made Colonel of the 41st Regiment of Foot in 1808. Following a period of dispute with the civil government of Madras over his exclusion from its council, and the affair of the arrest of Quartermaster-General John Munro, he resigned his commission in January 1809 and took ship for England on the East Indiaman Lady Jane Dundas. The ship was lost with all hands near the Cape of Good Hope in March 1809.
