The US Cavalry's clash with the Nez Perce provides an excellent case study of unconventional warfare. The battles forced the Nez Perce Indians and their horses to flee on a perilous journey that sent them1,600 miles throughout the vast Northwest of the United States. Why did the US Army fail to achieve decisive victory over the Nez Perce in 1877; and what lessons can be taken from this historical case and applied to today's wars. The author provides a thoughtful and well researched look into this little known campaign.
