In the days following the Battle of Birch Coulie, the decisive battle in the deadly Dakota War of 1862, one of President Lincoln's private secretaries wrote: "There has hardly been an outbreak so treacherous, so sudden, so bitter, and so bloody, as that which filled the State of Minnesota with sorrow and lamentation." Even today, at the 150th anniversary of the Dakota War, the battle still raises questions and stirs controversy. In Birch Coulie John Christgau recounts the dramatic events surrounding the battle. American history at its narrative best, his book is also a uniquely balanced and accurate chronicle of this little-understood conflict, one of the most important to roil the American West.
