LT Lyman Kidder, ten 2nd Cavalry troopers, and a Lakota scout named Red Bead were chased, surrounded, and killed by a large party of Cheyenne warriors near the banks of Beaver Creek while riding with a dispatch for George Custer in Kansas on June 29, 1867. The dispatch party had misread Custer's trail, partly because Custer had, as usual, disobeyed orders concerning his line of march. Johnson has done some useful field work to identify the actual site and to recover artifacts (uniform and equipment bits, expended and unexpended ammunition), and to reconstruct the last minutes of the doomed patrol. He also strings together what little is known of Kidder's life, including his service in the Dakota Uprising campaign in Minnesota, and makes some useful connections between Kidder's congressman father and the founding of the University of Soth Dakota, as well as the opening of theBlack Hills to white settlement, which was a great loss for the Lakota. The book is handomely ilustrated, including the painting reproduced on the cover, but its slim beypnd the bare bones of the story. (Field work aside, most of what we know rests on Custer's "My Life on the Plains," and on his official report.)
