The first comprehensive treatments of this subject were published very recently, in 2012 and 2014. These are An American Genocide: The United States and the California Indian Catastrophe, 1846-1873 by Benjamin Madley, and Murder State: California’s Native American Genocide, 1846-1873 by Brendan Lindsay.

Over the past few months, I’ve read these books and have been working on this report. More than any other aspect of local history I’ve written about, this has been the most difficult. This is not because these books are not well-written. It is because this topic is, to quote Madley, “unrelentingly grim.” This project has taken me longer than normal because it is emotionally very heavy. It is profoundly disturbing and unpleasant.
