The U.S. 1st Infantry Division (1st ID), familiarly known as the Big Red One, adapted to dynamic battlefield conditions through-out the course of its deployment during World War II by inno-vating and altering behavior, including tactics, techniques, and procedures. Both the Division's leaders and soldiers accom-plished this by thinking critically about their experiences in combat and wasting little time in putting lessons learned to good use. Simply put, they learned on the job - in battle and after bat-tle - and did so quickly.In telling the Division's WWII story, which includes an extensive photographic essay featuring many previously unpublished im-ages, Gregory Fontenot includes the stories of individual mem-bers of the Big Red One, from high-ranking officers to enlisted men fresh off the streets of Brooklyn, both during and after the conflict. Colonel Fontenot's rare ability to combine expert anal-ysis with compelling narrative history makes No Sacrifice Too Great an absorbing read for anyone interested in the military his-tory of the United States.
