David Maraniss tells the epic story of Vietnam and the sixties through the events of a few gripping, passionate days of war and peace in October 1967.
With meticulous and captivating detail, They Marched Into Sunlight brings that catastrophic time back to life while examining questions about the meaning of dissent and the official manipulation of truth—issues that are as relevant today as they were decades ago.

In a seamless narrative, Maraniss weaves together the stories of three very different worlds: the death and heroism of soldiers in Vietnam, the anger and anxiety of antiwar students back home, and the confusion and obfuscating behavior of officials in Washington. To understand what happens to the people in these interconnected stories is to understand America's anguish.

Based on thousands of primary documents and 180 on-the-record interviews, the book describes the battles that evoked cultural and political conflicts that still reverberate.
