Fearing for her life, Martha, at the urging of relatives, decided to free her deceased husbandâs slaves immediately. On January 1, 1801, a bit more than a year after Georgeâs death, Washingtonâs slaves gained their liberty.
The Hundred Years' War was a time of rapid military evolution. Weapons, tactics, army structure and the social meaning of war all changed, partly in response to the war's costs, partly through advancement in technology and partly through lessons that warfare taught.efore the Hundred Years' War, heavy cavalry (knights) was considered the most powerful unit in an army, but by the war's end, this belief had shifted. The heavy horse was increasingly negated by the use of the longbow (and, later, another long-distance weapon: firearms).
âThe Hundred Years Warâ is a term invented in the 18th century and popularized by Chrysanthe-Ovide Des Michelsâs 1823 tableau chronologique describing the period of conflict between 1337, when Philip VI of France formally confiscated the French possessions of his vassal, Edward III of England, and 1453, when the English attempt to recover Gascony (which had been overrun in 1451) was crushed at the battle of Castillon, leaving the English with no land in France except Calais.
