Linenthal's text suggests the multiple ways that Americans understand and experience battlefields. He emphasizes the quasi-religious language used around these spaces and extends this analogy into an argument about patriotic "orthodoxy" and "heresy." It's a useful, if somewhat simplistic, argument.
The book is organized around several case-studies and offers a solid overview of the controversies that swirl around American battlefield parks. The study of the American Indian Movement (AIM) activities at the Custer/Little Big Horn National Battlefield Park is particularly interesting and offers the most in-depth analysis of the racial and cultural dynamics to navigate on battlefields.
Unfortunately, it's now a dated text because after 9/11 and the bombing in Oklahoma City the concept of a "battlefield" is deeply problematic. The arguments he makes about patriotic orthodoxy feel shallow post-Patriot Act. Had this book provided a more theoretical take on battlefields it would probably still be relevant. Instead, by recapping controversies, it feels like a snapshot of a how Americans used/responded to battlefields at a particular period of time in the late 1980s.
