A Numerical Sketch of the War of 1812
The War of 1812 wasn’t just a war of conflicting interests — it was a clash of worldviews and cultures. In fact, the fundamentally divergent perspectives and goals of the major players help explain why, more than two centuries later, historians still struggle to say who won.
