The Fallen Timbers Battlefield was almost a shopping mall. That fact alone tells you something about how close this corner of northwest Ohio came to losing one of the most consequential sites in American history. On August 20, 1794, General "Mad" Anthony Wayne's Legion of the United States clashed with a confederacy of Native American tribes. The skirmish lasted less than an hour. The consequences stretched for decades: the resulting Treaty of Greenville handed the U.S. control of Ohio and cracked open the Northwest Territory for westward settlement.

The battlefield's actual location was only confirmed in 1995, when an anthropologist and a team of volunteers with metal detectors turned up musket balls in a soybean field, overturning two centuries of assumption.

VoiceMap's self-guided audio tours walk the 1.5-mile Northwest Territory Trail, weaving soldiers' journal entries and first-person accounts into the landscape to trace how a brief fight in a tangle of fallen trees reshaped a continent.
