Book excerpt: Brave Men, Gentle Heroes presents the honest, touching, and harrowing stories of men who served in World War II and of their sons who served in Vietnam -- fathers and sons bonded as deeply by their experience in war as by blood. Though World War II and Vietnam were vastly different -- the clear aims of World War II, the muddled goals of Vietnam; the hero's welcome accorded World War II veterans, the scorn heaped upon their sons -- each defined a generation. In these pages you will find war's carnage and heroism, purpose and futility, meaning and tragic meaninglessness. Molded by the awful crucible of war, these seemingly ordinary men offer extraordinary insights into what it means to be a warrior, an American, a father, and a son.
