I have three words for you: NEW MILITARY HISTORY!!! Beck beautifully illustrates a harsh, violent era built on vengeance that encapsulated the plains of North Dakota and Minnesota in the early 1860s in a way that other scholars have failed to do. By painstakingly seeking out, researching, and drawing conclusions from hundreds of primary sources left by the thousands of ordinary soldiers that took part in a war - and not JUST the official documents created by generals who wished to make every battle look like it was a complete success - Beck has accomplished detailing the complete story of the U.S. - Dakota War of 1862-65. Furthermore, sources detailing the actions and rationale of the Dakota Sioux, who was the military opponent of these previously-mentioned white American soldiers, are used throughout this book. Detailing the Indian's perspective on this three-year-long war - from the reasons they felt compelled to attack the whites as well as their excellent plan of attack at various battles like Big Mound, Killdeer Mountain, and The Badlands - is an aspect often ignored, or at least less emphasized, by Beck's predecessors.
It is likely still wise to read other histories (see Michael Clodfelter's and Doreen Chaky's works) of this time period in order to gather more detail on the entirety of this war (especially concerning the predicament of the Dakota in the decades before this final act of rebellion), but Beck's book remains a true treasure for the scholar or casual reader interested in how the ordinary soldier dealt with all aspects of this great war on the northern Plains.
