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).
Time scaled map of the war. The Hundred Years' War was fought between France and England during the late Middle Ages. It lasted 116 years from 1337 to 1453. The war started because Charles IV of France died in 1328 without a son. Edward III of England then believed he had the right to become the new king of France through his mother.
