THE EPIC TRUE STORY OF THE AMERICAN BUFFALO—BY MICHAEL PUNKE, THE AUTHOR OF THE REVENANT, NOW A MAJOR MOTION PICTURE STARRING LEONARDO DICAPRIO

In the last three decades of the nineteenth century, an American buffalo herd once numbering 30 million animals was reduced to twelve. It was the era of Manifest Destiny, a Gilded Age that treated the West as nothing more than a treasure chest of resources to be dug up or shot down. The buffalo in this world was a commodity, hounded by legions of swashbucklers and unemployed veterans seeking to make their fortunes. Supporting these hide hunters, even buying their ammunition, was the U.S. Army, which considered the eradication of the buffalo essential to victory in its ongoing war on Native Americans.

Into that maelstrom rode young George Bird Grinnell. A scientist and a journalist, a hunter and a conservationist, Grinnell would lead the battle to save the buffalo from extinction. Fighting in the pages of magazines, in Washington's halls of power, and in the frozen valleys of Yellowstone, Grinnell and his allies sought to preserve an icon from the grinding appetite of Robber Baron America.

Grinnell shared his adventures with some of the greatest and most infamous characters of the American West—from John James Audubon and Buffalo Bill to George Armstrong Custer and Theodore Roosevelt (Grinnell's friend and ally). A strikingly contemporary story, the saga of Grinnell and the buffalo was the first national battle over the environment. In Grinnell's legacy is the birth of the conservation movement as a potent political force.
