A fascinating insight into the life and the extraordinary, but overlooked legacy of Captain John McClallen. The story of Captain John McClallen has long been neglected as a mere footnote to the history of the American West. But, as this engaging volume reveals, he played a crucial, if largely unrecognized role in the evolution of the United States. By Honor and Right reconstructs the life and astonishing audacity of the first United States officer to follow the Lewis and Clark Expedition. Originally tasked with opening up the Santa Fe Trail, but due to circumstances beyond control McClallen instead entered the Pacific Northwest and discovered a viable route across the continent. And for a brief but crucial moment blocked British expansion of trade in the region, allowing the United States to gain a lasting foothold over the continent.
