It gives me great pleasure to write a word of introduction to this interesting and important book that Mr. Williams has written. The story of the Negro soldier is one of the romances of American history. Even in the days of the Revolution and the War of 1812 he played an honorable part; but it was the Civil War that gave him his first large opportunity, and at Port Hudson, Fort Wagner, or Fort Pillow he passed through the baptism of fire, striving that the emancipation of his people might be guaranteed and the integrity of his country preserved. We also remember another war, and Santiago and San Juan Hill, and not only how Negro men went gallantly to the charge but also how the soldiers in a black regiment faced pestilence and fever that their white comrades might be saved. Then came Carrizal, strange prelude of the great conflict to come; and once more, at an unexpected moment, the soul of the nation was thrilled by the courage of the Tenth Cavalry. “Theirs not to make reply; theirs but to do and die.” So in the face of odds they obeyed orders and died beneath the Mexican stars. The recent World War, however, brought to the Negro people of the United States an interest and an anxiety surpassed only by the expectant hope in the days of the Civil War. They had come to the end of an era, and all the incidents and problems of their life in America were suddenly brought to the testing. Vast forces beyond their control were changing the destinies of thousands--in migration, in economic freedom, and even in spiritual outlook; and unhappy events at East St. Louis and Houston but made the situation more critical. They were eager to serve, but at once they came face to face with questions that concerned the very foundations of their citizenship. Would the men of the race, or would they not, be permitted to train and serve as officers? If so, would they be dealt with as a distinct and separate race, as was the case with no other race in the country, or simply on the basis of physical and mental fitness? Why, moreover, on the registration card for the draft should the Negro be singled out for a special corner? To some people such questions may have seemed unimportant, but to the Negroes themselves they meant nothing less than life itself, and they followed the fortunes of their sons and their husbands accordingly.
