August 20 (Saturday) brought hurricane-force winds to the interior northwest, whipping the hundreds of small fires into one or two much larger blazing infernos. Such a conflagration was impossible to fight; there were too few men and supplies. The United States Forest Service (then called the National Forest Service) was only five years old at the time and unprepared for the possibilities of the dry summer or a fire of this magnitude, though all summer it had been urgently recruiting as many men as possible to fight the hundreds of fires already burning, many with little forestry or firefighting experience. Earlier in August President William Howard Taft had authorized the addition of military troops to the effort, and 4,000 troops, including seven companies from the U.S. Army's 25th Infantry Regiment (known as the Buffalo Soldiers), were brought in to help fight the fires burning in the northern Rockies. The arrival of the Buffalo Soldiers troops almost doubled the black population of Idaho.
