See it on the Battles & Wars map →What happened
On December 16, 1944, about 200,000 German troops, later more, attacked through the Ardennes forest of Belgium and Luxembourg under fog that grounded Allied aircraft, driving a 'bulge' into thin US lines. Americans delayed them at St. Vith and held the road hub of Bastogne, where General Anthony McAuliffe answered a surrender demand with 'Nuts!' Patton's Third Army swung north to relieve Bastogne. Clearing skies, fuel shortages and Allied reserves broke the offensive by late January.
Why it matters
The largest US battle of the war, it cost about 19,000 American lives and used up Germany's last armored reserves in the west, hastening its defeat.
How we know
US Army after-action reports, postwar interviews with German commanders, Allied intelligence records that missed the buildup, and memorials at Bastogne and the Luxembourg American Cemetery, where Patton is buried.
Still debated
Why Allied intelligence missed the buildup despite warning signs, and whether the offensive ever had a real chance of reaching Antwerp, remain debated.
Connections (4)
▸D-Day (Normandy landings) led to Germany's last gamble at Battle of the BulgeWell documented
The connection
After breaking out of Normandy, Allied armies raced across France and Belgium until their supply lines stretched thin in autumn 1944. Hitler gambled that a surprise strike through the lightly held Ardennes could retake the port of Antwerp, split the British and American armies, and force a negotiated peace in the west.
When and how
From Normandy, June–August 1944, to the Ardennes of Belgium and Luxembourg, December 16, 1944.
How we know
Hitler's orders for the offensive (code-named Watch on the Rhine) and his generals' postwar testimony set out its aims.
Debates and open questions
German generals such as Rundstedt and Model thought reaching Antwerp unrealistic; why Hitler believed it could break the alliance is debated.
▸Battle of the Bulge was Germany's last major western offensive in World War IIWell documented
The connection
The Bulge consumed Germany's last reserves of tanks, fuel and trained men in the west. After it failed, German defenses were weaker, the Allies crossed the Rhine in March 1945, and the Soviets, attacking in the east from January 12, pushed on toward Berlin.
When and how
Ardennes, December 1944 – January 1945: about 75,000–89,000 US casualties and an estimated 63,000–100,000 German, including wounded and captured.
How we know
US and German records show heavy, irreplaceable German losses in tanks and aircraft, including the failed January 1 air attack, Operation Bodenplatte.
Debates and open questions
Some argue the offensive delayed the Allies only about six weeks; whether it shortened or lengthened the war overall is debated.
▸Dwight D. Eisenhower led the Allied response to Battle of the BulgeWell documented
The connection
Eisenhower quickly saw the German attack as a major offensive, rushed reserves to hold Bastogne, ordered Patton to turn north, and temporarily gave Montgomery command of US armies on the bulge's northern side, a move that strained Anglo-American relations.
When and how
Verdun, France, December 19, 1944: Eisenhower's conference with Bradley, Patton and other commanders.
How we know
Allied headquarters (SHAEF) records, accounts of the Verdun conference, and memoirs by Eisenhower, Bradley, Patton and Montgomery.
Debates and open questions
Montgomery's January 7 press conference, seen as claiming credit, angered Americans; how much the dispute reflected real differences in strategy is debated.
▸Proximity fuze first hit ground targets in the Battle of the BulgeWell documented
The connection
Kept off land battlefields for fear Germany would recover a dud and copy it, the fuze was released to US Army artillery in December 1944. In the Bulge, shells bursting in the air above German troops in the open caused heavy casualties. Patton wrote that the 'funny fuze' was devastating.
When and how
Ardennes, Belgium and Luxembourg, from about December 18, 1944; US Army artillery firing on attacking German troops.
How we know
US Army ordnance reports, Patton's December 1944 letter to the Army's chief of ordnance, and German accounts of air bursts.
Debates and open questions
How much it mattered next to clearing weather, Allied air power and the stand at Bastogne is hard to measure.
