This story ran as a serial under the title, “In Defence of His Flag,” in that popular monthly, _The American Boy_. As a serial it created a demand for its publication in book form, hence the present volume. The story has been somewhat revised but not materially altered. The purely historical portions are based on the United States records and the records of the Confederacy. Once again I thank the thousands and thousands of boys, not only in this country but also in other lands, who take so much interest in what I have written for them. May the present volume please you in every way and do you good. EDWARD STRATEMEYER. _May 15, 1907._ CONTENTS CHAPTER PAGE I. SIGNS OF WAR 1 II. IN A HOSTILE NEIGHBORHOOD 16 III.
