Two of the most important source documents of the 19th century Indian wars. General Alfred Terry was the commander of the Yellowstone Expedition that ended in the death of George Armstrong Custer and 261 of his men. Terry's official report is included in this book and is a document used by virtually all Custer writers. Also included is the field diary Terry kept while on expedition. It begins in mid-May, 1876 and ends in August. Noted are incidents of Custer and Reno acting without authority or against orders.
