World War II remains the defining experience for the U.S. Army in the twentieth century. It has had a lasting impact on the nation and its place in the world and on the Army and the way it organizes and fights. Although historians have written numerous volumes concerning this global conflict, some gap in the literature remain. In particular, the subject of an American field army headquarters and its organization and role have attracted little attention. Studies on the personalities and styles of individual commanders exist, but the command posts themselves-the ways in they were structures and operated and the functions they performed-have not been much explored. With A Command Post at War: First Army Headquarters in Europe, 1943-1945, the Center of Military History attempts to redress this shortcoming. This study addresses the First Army headquarters in the European theater from its activation in October 1943 to V-E Day in May 1945. Under Generals Omar N. Bradley and Courtney H. Hodges, the First Army headquarters oversaw the American landings on D-Day, the breakout from the Normandy beachhead, the battle of H]rtgen Forest along the German frontier, the defense of the northern shoulder during the Battle of the Bulge, and the crossing of the Rhine River at Remagen prior to the final American drive into central Germany. In examining the First Army headquarters' role, this volume shows the army headquarters of World War II as a complicated organization with functions ranging from the immediate supervision of tactical operations to long-range operational planning and the sustained support of frontline units. The commander and staff faced the problem of coordination with Allied counterpartsas well as with headquarters and units from other services. Inadequate information and the limitations of technology added to their challenges. The human dimension was always important, and at times critical, in affecting the work of the headquarters under the stresses of a difficult campaign against an obstinate and resourceful foe. Although times have changed and the modern Army focuses more on regional conflicts and contingencies than on global warfare, we can still learn much from the experience of the First Army headquarters. The Gulf War reemphasized the role of an army headquarters in a theater of operations as a pertinent issue for today's military professional. By examining the experience of soldiers in past conflicts we gain the deeper perspectives and understandings necessary to meet the challenges facing the Army today and in the future.

In the winter of 1944–1945, Hitler sought to divide Allied forces in the heavily forested Ardennes region of Luxembourg and Belgium. He deployed more than 400,000 troops in one of the last major German offensives of the war, which became known as the Battle of the Bulge, in a desperate attempt to regain the strategic initiative in the West. Hitler’s effort failed for a variety of reasons, but many historians assert that Lieutenant General George S. Patton Jr.’s Third Army was ultimately responsible for securing Allied victory. Although Patton has assumed a larger-than-life reputation for his leadership in the years since World War II, scholars have paid little attention to his generalship in the Ardennes following the relief of Bastogne. In Advance and Destroy, Captain John Nelson Rickard explores the commander’s operational performance during the entire Ardennes campaign, through his “estimate of the situation,” the U.S. Army’s doctrinal approach to problem-solving. Patton’s day-by-day situational understanding of the Battle of the Bulge, as revealed through ULTRA intelligence and the influence of the other Allied generals on his decision-making, gives readers an in-depth, critical analysis of Patton’s overall effectiveness, measured in terms of mission accomplishment, his ability to gain and hold ground, and a cost-benefit analysis of his operations relative to the lives of his soldiers. The work not only debunks myths about one of America’s most controversial generals but provides new insights into his renowned military skill and colorful personality.
