The projected five volume Handbook of the American Frontier is intended as a work of first reference that provides insights into Indian-white relationships during the first four centuries of our colonial and United States history. Based upon both primary and secondary sources, it includes the Indian viewpoint as well as the white, and provides references to assist the reader to additional information. Volume IV of the Handbook is an account of men and events important in the frontier history of the West from the earliest Spanish explorations to the last Indian battle, fought in 1918.
