A nineteenth-century attack by Native Americans on a Presbyterian mission in what would become the Oregon Territory proved to be a turning point in the history of the American West. This book examines the tangled legacy of that event.In 1836, Marcus and Narcissa Whitman, devout missionaries from upstate New York, established a Presbyterian mission on Cayuse Indian land near what is now the fashionable wine capital of Walla Walla, Washington. Eleven years later, a group of Cayuses killed the Whitmans and eleven others in what became known as the Whitman Massacre. The attack led to a war of retaliation against the Cayuse; the extension of federal control over the present-day states of Washington, Oregon, Idaho, and parts of Montana and Wyoming; and martyrdom for the Whitmans. Today, the Whitmans are more likely to be demonized as colonizers than revered as heroes. Historian and journalist Cassandra Tate takes a fresh look at the personalities, dynamics, disputes, social pressures, and shifting legacy of a pivotal event in the history of the American West.
