摘要:On New Year’s Eve, 1775, American revolutionary General Richard Montgomery’s ill-fated decision to lead the assault through a fallen barricade in Québec City was decisive in preserving a British presence in North America. Had Montgomery instead used his troops as a shield, he might have survived and captured Québec, which would now be part of the United States. This example illustrates how complex battles and wars can be sensitive to a single event or decision.
