Battle of the Bulge, (December 16, 1944–January 16, 1945), the last major German offensive on the Western Front during World War II—an unsuccessful attempt to push the Allies back from German home territory. The name Battle of the Bulge was appropriated from Winston Churchill’s optimistic description in May 1940 of the resistance that he mistakenly supposed was being offered to the Germans’ breakthrough in that area just before the Anglo-French collapse; the Germans were in fact overwhelmingly successful. The “bulge” refers to the wedge that the Germans drove into the Allied lines.

The Allied breakout from Normandy

After their invasion of Normandy in June 1944, the Allies moved across northern France into Belgium during the summer but lost momentum in the autumn. Apart from an abortive thrust to Arnhem, Netherlands, the efforts of the Allied armies in western Europe during September and October 1944 amounted to little more than a process of nibbling. Meanwhile, the German defense was being continuously strengthened with such reserves as could be relocated from elsewhere and with the freshly raised forces of the Volkssturm (“home guard”). German numbers were also bolstered by those troops who had managed to withdraw from France. A general offensive launched in mid-November by all six Allied armies on the Western Front brought disappointingly small results at heavy cost; continued efforts merely exhausted the attacking troops.

The German attack plan

In mid-December Gen. Dwight D. Eisenhower, the supreme commander of the Allied Expeditionary Force, had at his disposal 48 divisions distributed along a 600-mile (nearly 1,000-km) front between the North Sea and Switzerland. For the site of their counteroffensive, the Germans chose the hilly and wooded country of the Ardennes. Because it was generally regarded as difficult country, a large-scale offensive there was likely to be unexpected. At the same time, the thick woods provided concealment for the massing of forces, whereas the high ground offered a drier surface for the maneuvers of tanks. An awkward feature from an offensive point of view, however, was the fact that the high ground was intersected with deep valleys where the through roads became bottlenecks where a tank advance was liable to be blocked. The aims of the German counteroffensive were far-reaching: to break through to Antwerp, Belgium, by an indirect move, to cut off the British army group from American forces as well as from its supplies, and then to crush the isolated British. Overall command of the offensive was given to Field Marshal Gerd von Rundstedt.

The Fifth Panzer Army, led by Hasso, Freiherr (baron) von Manteuffel, was to break through the U.S. front in the Ardennes, swerve westward, and then wheel northward across the Meuse, past Namur to Antwerp. As it advanced, it was to build up a defensive flank barricade to shut off interference from the U.S. armies farther south. The Sixth Panzer Army, under SS commander Sepp Dietrich, was to thrust northwestward on an oblique line past Liège to Antwerp, creating a strategic barrier astride the rear of the British and of the more northerly American armies. To those two panzer armies the Germans gave the bulk of the tanks that they could scrape together. To minimize the danger from a speedy intervention of Anglo-American air power, which was vastly greater than their own, the Germans launched their stroke when the meteorological forecast promised them a natural cloak; indeed, for the first three days, mist and rain kept the Allied air forces on the ground.

The German offensive and the Battle of Bastogne

Aided by its surprise, the German counteroffensive, which started before dawn on December 16, 1944, made menacing progress in the opening days, creating alarm and confusion on the Allied side. The Fifth Panzer Army bypassed Bastogne (which was held throughout the offensive by the U.S. 101st Airborne Division under the tenacious leadership of Gen. Anthony McAuliffe) and by December 24 had advanced to within 4 miles (6 km) of the Meuse River. Time and opportunities were lost, however, through gasoline shortages resulting from wintry weather and from growing Allied air attacks, and the German drive faltered. This frustration of the German advance was largely due to the way in which outflanked U.S. detachments held Bastogne and several other important bottlenecks in the Ardennes as well as to the speed with which British Field Marshal Bernard Montgomery, who had taken charge of the situation on the northern flank, swung his reserves southward to forestall the Germans at the crossings of the Meuse.

On December 22 the Americans in Bastogne received an ultimatum from the Germans, demanding the “honorable surrender” of the city within two hours. McAulliffe’s now legendary reply read:

  • To the German Commander:
  • NUTS!
  • The American Commander

Gen. George S. Patton’s Third Army relieved Bastogne on the 26th, and on January 3, 1945, the U.S. First Army began a counteroffensive. Between January 8 and January 16 the Allied armies concentrated their strength and were attempting to pinch off the great German wedge driven into their front, but the Germans carried out a skillful withdrawal that took them out of the potential trap. Judged on its own account, the Battle of the Bulge had been a profitable operation for Germany, for, even though it fell short of its objectives, it upset the Allies’ preparations and inflicted much damage at a cost that was not excessive for the effect. Viewed in relation to the whole situation, however, the counteroffensive had been a fatal operation. While the Allies suffered some 75,000 casualties, Germany lost 120,000 men and stores of matériel that it could ill afford to replace. Germany had thus forfeited the chance of maintaining any prolonged resistance to a resumed Allied offensive. It brought home to the German troops their incapacity to turn the scales and thereby undermined such hopes as they had retained.

offensive tactics

blitzkrieg, military tactic calculated to create psychological shock and resultant disorganization in enemy forces through the employment of surprise, speed, and superiority in matériel or firepower. Blitzkrieg is most commonly associated with Nazi Germany during World War II even though numerous combatants used its techniques in that war. Its origins, however, can be traced to the 19th century, and elements of blitzkrieg have been used in present-day conflicts.

Blitzkrieg in principle

The concept of blitzkrieg was formed by Prussian military tactics of the early 19th century, which recognized that victory could come only through forceful and swift action because of Prussia’s relatively limited economic resources. It had its origins with the Schwerpunktprinzip (“concentration principle”) proposed by Carl von Clausewitz in his seminal work On War (1832). Having studied generals who predated Napoleon, Clausewitz found that commanders of various armies had dispersed their forces without focused reasoning, which resulted in those forces’ being used inefficiently. So as to eliminate that wasteful use of manpower, he advocated for a concentration of force against an enemy. All employment of force should have an effective concentration in a single moment, with a single action, Clausewitz argued. Clausewitz called that concentration the Schwerpunkt (“centre of gravity”) where it was most dense, identifying it as the effective target for attack.

For historical generals, from Alexander the Great of ancient Macedonia to Frederick II of 18th-century Prussia, their armies functioned as the centre of gravity. If the army was destroyed, the commander would be considered a failure. In smaller countries or countries engaged in internal strife, according to Clausewitz’s reasoning, the capital becomes the centre of gravity and should be identified as the Schwerpunkt. Beginning in the 20th century, technological advances such as radio, aircraft, and motorized vehicles allowed a commander to concentrate force at the Schwerpunkt so as to annihilate the opposition and achieve victory. During World War II each blitzkrieg campaign contained a Schwerpunkt that gave it meaning and substance, with doctrines of mobile warfare expounded by British military theorists J.F.C. Fuller and Sir Basil Liddell Hart providing the tactics necessary to translate the theory into action.

Germany invades Poland, September 1, 1939, using 45 German divisions and aerial attack. By September 20, only Warsaw held out, but final surrender came on September 29.

Once the strategic Schwerpunkt had been identified, the attack could commence, using the concept of Kesselschlacht (“cauldron battle”). A frontal attack would immobilize the enemy while forces on the flanks would execute a double envelopment, forming a pocket called a Kessel (“cauldron”) around the enemy. Once surrounded, the opposing army, demoralized and with no chance of escape, would face the choice of annihilation or surrender.

Blitzkrieg in practice

Tested by the Germans during the Spanish Civil War in 1938 and against Poland in 1939, the blitzkrieg proved to be a formidable combination of land and air action. Germany’s success with the tactic at the beginning of World War II hinged largely on the fact that it was the only country that had effectively linked its combined forces with radio communications. The use of mobility, shock, and locally concentrated firepower in a skillfully coordinated attack paralyzed an adversary’s capacity to organize defenses, rather than attempting to physically overcome them, and then exploited that paralysis by penetrating to the adversary’s rear areas and disrupting its whole system of communications and administration. The tactics, as employed by the Germans, consisted of a splitting thrust on a narrow front by combat groups using tanks, dive bombers, and motorized artillery to disrupt the main enemy battle position at the Schwerpunkt. Wide sweeps by armoured vehicles followed, establishing the Kessel that trapped and immobilized enemy forces. Those tactics were remarkably economical of both lives and matériel, primarily for the attackers but also, because of the speed and short duration of the campaign, among the victims.

Blitzkrieg tactics were used in the successful German invasions of Belgium, the Netherlands, and France in 1940, which saw audacious applications of air power and airborne infantry to overcome fixed fortifications that were believed by the defenders to be impregnable. The Kesselschlacht campaigns on the Eastern Front were staggering in scale, with Kessels that covered vast swathes of territory, enveloping hundreds of thousands of troops. Blitzkrieg tactics were also used by the German commander Erwin Rommel during the desert campaigns in North Africa.

After those initial German successes, the Allies adopted this form of warfare with great success, beginning with Stalingrad and subsequently used by commanders such as U.S. Gen. George Patton in the European operations of 1944. The Germans’ last successful Kessel campaign was against the British paratroops at Arnhem, Netherlands, an encirclement that came to be known as the Hexenkessel (“witches’ cauldron”). By the end of the war, Germany found itself defeated by the strategic (Schwerpunkt) and tactical (Kesselschlacht) concepts that had initially brought it such success. German armies were destroyed at Falaise in France, the Scheldt in the Netherlands, and the Bulge in Belgium and on the Eastern Front at Cherkasy (in modern Ukraine), Memel (now Klaipėda, Lithuania), and Halbe, Germany. The last great battle of World War II fought using blitzkrieg tactics was the Battle of Berlin (April–May 1945).

Later manifestations of blitzkrieg tactics were the combined air and ground attacks by Israeli forces on Syria and Egypt during the Six-Day War (June 1967) and the Israeli counterattacks and final counteroffensive of the Yom Kippur War (October 1973). The “left hook” flanking maneuver executed by U.S. Gen. Norman Schwarzkopf during the Persian Gulf War also utilized elements of blitzkrieg tactics, with a combined arms offensive that destroyed the Iraqi army in Kuwait in a period of just three days.
