The Battle of the Bulge, also known as the Ardennes Counteroffensive, was launched through the densely forested Ardennes region of Wallonia in eastern Belgium, northeast France, and Luxembourg. The offensive took place from 16 December 1944 to 25 January 1945. But the battle was lost to the German forces. The "Bulge" was the largest and bloodiest single battle fought by the United States in World War II and the third-deadliest campaign in American history.
In recognition of his senior position in the Allied command, on December 20, 1944, he was promoted to General of the Army, equivalent to the rank of Field Marshal in most European armies. In this and the previous high commands he held, Eisenhower showed his great talents for leadership and diplomacy. Although he had never seen action himself, he won the respect of front-line commanders. He interacted adeptly with allies such as Winston Churchill, Field Marshal Bernard Montgomery, and General Charles de Gaulle. He had serious disagreements with Churchill and Montgomery over questions of strategy, but these rarely upset his relationships with them. He dealt with Soviet Marshal Zhukov, his Russian counterpart, and they became good friends.
