This is a handbook for dads to help them train their sons for battle. In this book you will find lessons for manhood that arise from the WWII battle for Iwo Jima with its fighter planes, amphibious assaults, foxholes, cave warfare, and flamethrowers. It contains seventeen critical exhortations that I believe fathers must deliver to their sons. Why? To discipline them to be the mighty warriors God intends them to be. These were the things I told my own son David as he was growing up. This is a book about leading boys to be truly great boys—and someday, men. It uses a personal, modern example (the example of my father and some other men I’ve met) to illustrate what God has already said in Scripture. It is appropriate to remember the WWII generation. That generation of warriors spent their youth laboring to eke out a living after the Depression. They forged their character on hard work and frugality. They were farm boys and clerks and ditch diggers. Most were not raised with silver spoons and almost none of them had much leisure time. Then they went to war and saved western civilization from the godless tyranny of Hirohito and Adolph Hitler. A generation of heroes does not just pop up out of nowhere. It is prepared by its fathers.
