The U.S. 1st Infantry Division (1st ID), familiarly known as the Big Red One, adapted to dynamic battlefield conditions throughout the course of its deployment during World War II by innovating and altering behavior, including tactics, techniques, and procedures. The evidence shows that both the Division’s leaders and soldiers did so 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 battle—and did so quickly. This is remarkable in that the terrain, weather, and the enemy changed as the Division fought its way through North Africa, Sicily, France, Belgium, Germany, and finally Czechoslovakia; equally important were constraints imposed on the 1st ID by manpower shortages (some of them critical), structural changes, and even weapons capabilities, all of which required continual adjustment.

In telling the Division’s WWII story, not only in the historical narrative but in an extensive Photographic Essay—which comprises 65 images, many of which have never been reproduced—to appear in the center of the work, Gregory Fontenot includes the stories of individual members of the Big Red One, officers as well as enlisted men, having gleaned information from the hundreds of memoirs, diaries, and postwar interviews he either consulted or personally conducted, making his third volume in the American Military Experience series a meaningful and memorable one.
