5(Includes maps) During most of the eleven months between D-day and V-E day in Europe, the U.S. Army was carrying on highly successful offensive operations. As a consequence, the American soldier was buoyed with success, imbued with the idea that his enemy could not strike him a really heavy counterblow, and sustained by the conviction that the war was nearly won. Then, unbelievably, and under the goad of Hitler's fanaticism, the German Army launched its powerful counteroffensive in the Ardennes in December 1944 with the design of knifing through the Allied armies and forcing a negotiated peace. The mettle of the American soldier was tested in the fires of adversity and the quality of his response earned for him the right to stand shoulder to shoulder with his forebears of Valley Forge, Fredericksburg, and the Marne. This is the story of how the Germans planned and executed their offensive. It is the story of how the high command, American and British, reacted to defeat the German plan once the reality of a German offensive was accepted. But most of all it is the story of the American fighting man and the manner in which he fought a myriad of small defensive battles until the torrent of the German attack was slowed and diverted, its force dissipated and finally spent. It is the story of squads, platoons, companies, and even conglomerate scratch groups that fought with courage, with fortitude, with sheer obstinacy, often without information or communications or the knowledge of the whereabouts of friends. In less than a fortnight the enemy was stopped and the Americans were preparing to resume the offensive. While Bastogne has become the symbol of this obstinate, gallant, and successful defense, this work appropriately emphasizes the crucial significance of early American success in containing the attack by holding firmly on its northern and southern shoulders and by upsetting the enemy timetable at St. Vith and a dozen lesser known but important and decisive battlefields. The hard fighting that preceded the Battle of the Bulge has been recounted in two volumes, "The Siegfried Line Campaign", and Dr. Cole's own earlier work, The Lorraine Campaign. Events after it will be related in "The Last Offensive", now in preparation. Two other volumes in this subseries, "The Supreme Command" and "Logistical Support of the Armies", Volume II, are useful supplements to the Ardennes volume. In re-creating the Ardennes battle, the author has penetrated "the fog of war" as well as any historian can hope to do. No other volume of this series treats as thoroughly or as well the teamwork of the combined arms-infantry and armor, artillery and air, combat engineer and tank destroyer-or portrays as vividly the starkness of small unit combat. Every thoughtful student of military history, but most especially the student of small unit tactics, should find the reading of Dr. Cole's work a rewarding experience.
