To mark the tenth anniversary of the 9/11 attacks, a group of volunteers acknowledged the fallen by posting 2,996 American flags at a city park in St. Louis, Missouri. One of the flags honored New York City firefighter Michael Weinberg, a first responder who died at Ground Zero. In a twist of fate, this particular flag went unnoticed at auction after the event but, as a result, would make a remarkable journey through the Midwest. Under One Flag chronicles this journey with poignant, richly illustrated stories of American heroism and the conviction of those intent on paying tribute. Key among the latter are grassroots organizer Rick Randall and also Larry Eckhardt, known as The Flag Man for placing flags along the routes of military funerals. Through these efforts, Michael s flag would fly in Preston, Iowa, to honor Marine Corporal Zach Reiff, who died serving his country in Afghanistan. Under One Flag shows how lives interweave when compassion serves as the common tie. It is the collective story of people who want nothing but give everything.
