By late 1944, the Third Reich was on the defensive on both the Eastern and Western Fronts. Adolf Hitler, believing the alliance between the Western powers and the Soviet Union was weakening, decided on a bold offensive in the Ardennes region of Belgium and Luxembourg. His goal was to break through American lines, reach the port of Antwerp, and potentially split the Allied coalition.
Hitler’s plan was ambitious, calling for around 45 divisions to be mobilized behind the Siegfried Line. The strategy was to defeat the US First Army and isolate the British Second Army in the north, trapping them in a pocket similar to the 1940 invasion of France. Hitler believed that a successful offensive would buy Germany time to produce its "secret weapons" and force the Allies to reconsider their alliance with the Soviet Union.
Most German generals considered the offensive in the Ardennes unfeasible, viewing it as a product of Hitler’s fantasies. To ensure their compliance, Hitler summoned the high command to a secret meeting on the night of December 11th. The generals were stripped of their weapons by SS men and taken to Ziegenberg Castle, where they were forced to sit under guard. Hitler then entered and enthusiastically explained his plan, demanding they sign a document confirming their support. The generals, humiliated and terrified, had no choice but to accept.
The logistical challenge of concentrating forces in the Ardennes was considerable. Troops and resources were diverted from the Eastern Front, with over 10,000 railway wagons used to transport men and material. The movement was conducted under strict secrecy, with nighttime transport of tanks to evade aerial reconnaissance. By early December, the Wehrmacht was better equipped than at any other point in the war, with formidable tanks like the Tiger, Panther, and King Tiger.
Hitler entrusted the main effort of the offensive to his elite Waffen-SS formations. The Sixth SS Panzer Army, under the command of Josef Dietrich, was assigned to lead the attack in the northern sector. This army included the veteran 1st SS Panzer Division Leibstandarte Adolf Hitler and the 12th SS Panzer Division Hitlerjugend. In total, four SS Panzer divisions formed the core armored spearhead of the German offensive.
The Luftwaffe also played a key role, with aircraft such as the Messerschmitt Me 262, the first operational jet fighter, as well as the Bf 109 and Fw 190. Heavy artillery, including 88 mm flak cannons and Nebelwerfer rocket launchers, was positioned in the Ardennes hills. The V1 and V2 missiles, with hidden launch ramps in the forests, represented a serious strategic threat. Innovations like the StG 44 assault rifle and the first night vision goggles gave German troops an advantage during nighttime operations.
Operation Wacht am Rhein, also known as the Battle of the Bulge, was originally scheduled for December 10th but was delayed until the 16th due to poor weather. Field Marshal Gerd von Rundstedt was appointed as the main commander, though he remained skeptical due to the lack of fuel. The German attack plan involved a rapid blitzkrieg-style offensive launched in three main columns, with 200,000 soldiers, 2,000 tanks, 1,900 artillery pieces, and 3,000 aircraft.
The Ardennes was a difficult terrain of dense vegetation, steep hills, and deep valleys, all covered in thick snow. The US Army in the region was scattered and demoralized after suffering defeats in operations like Market Garden and the Battle of Hürtgen Forest. On December 7th, Supreme Allied Commander Dwight D. Eisenhower convened a meeting in Maastricht to discuss a counter-offensive, but the Allies soon found themselves under attack instead.
On December 16th, 1944, German forces unleashed a ferocious bombardment over the Ardennes with more than 1,500 artillery pieces. This was followed by the launch of V1, V2, and Rheinbote missiles, which struck the cities of Liège and Antwerp. The US V Corps, stationed at the vanguard, was caught in the devastating assault. German forces used powerful spotlights to illuminate the low-hanging clouds, creating an artificial glow that blinded American troops.
As German lines pushed forward, 120 Junkers Ju 52 aircraft took off with paratroopers for an airborne assault. The operation was poorly organized, and many paratroopers were scattered throughout nearby forests. The second wave, under the command of Otto Skorzeny, had more success. The 150th Panzer Special Brigade, formed by elite commandos disguised in US Army uniforms, infiltrated enemy lines and wreaked havoc by changing road signs and placing red tape to simulate minefields.
Skorzeny’s commandos misled several American units, causing an entire column to take the wrong road. Near Malmedy, they attacked a key crossroads, severing communications. The infiltration caused absolute chaos, with roads becoming clogged with traffic jams and confused Allied troops arresting hundreds of innocent soldiers. The rumor that German commandos were attempting to assassinate Eisenhower spread rapidly, and Eisenhower confined himself to his headquarters for 10 days.
Before dawn on December 16th, the German Fifth Panzer Army made contact with US positions. The advance was so swift that many American soldiers surrendered without firing a shot. To the north, the Sixth SS Panzer Army launched a fierce armored assault against the US 99th Infantry Division near Höfen. The troops of the 1st SS Panzer Division, leading the attack, were the first to clash with the Americans.
Kampfgruppe Peiper, composed of 124 armored vehicles and 2,000 men, advanced swiftly to Losheim. However, a massive buildup of vehicles caused severe traffic jams. The group’s commander, Joachim Peiper, ordered his forces to ram through the vehicles of the 12th Volksgrenadier Division, regardless of the damage caused. By midday, Peiper’s armored units encountered the 3rd Parachute Division, and the airborne troops were able to board the German tanks.
Peiper’s column reached the town of Buchholz, where the American defenders surrendered without a fight. He then captured the Bullingen airfield, taking 50 prisoners and seizing a fuel depot full of gasoline. By late afternoon, the 1st SS Panzer Corps succeeded in breaking through the defenses of the US 99th Infantry Division, creating a major breach in the front and splitting the US V Corps in two.
By midnight, the Allies had lost nearly three divisions, and German forces were advancing at an astonishing speed. During the night, the Allies took urgent measures to send reinforcements. The 106th Infantry Division was dispatched south, and the veteran 1st Infantry Division, the Big Red One, was also mobilized. Unfortunately, the reinforcements arrived too late, and the 99th Division was ambushed in Elsenborn, suffering nearly 3,000 casualties.
On December 17th, the Allies finally understood the seriousness of the situation. Eisenhower gave the immediate order to mobilize the 82nd and 101st US Airborne divisions and selected Patton’s US Third Army to assist. The main challenge was that Patton’s forces were still far from the front, leaving the remaining Allied units with only one viable option: resist until exhaustion.
December 17th also became a dark day for the US Army following the discovery of the horrific Malmedy massacre. Eighty-four American prisoners of war were coldly executed by Waffen-SS soldiers belonging to Kampfgruppe Peiper. The news of the massacre spread quickly, and Allied media used the event as a symbol of German cruelty. The bodies of the victims, found frozen in the snow, sparked widespread outrage within US ranks.
While Malmedy became a symbol of German atrocities, few knew that American forces also committed war crimes in retaliation. The Chenogne massacre, which took place in January 1945, was a direct reprisal for the crimes committed in Malmedy. Between 70 and 80 German prisoners were coldly executed by soldiers of the US 11th Armored Division. Unlike Malmedy, there were no survivors in Chenogne, and the events were kept secret for years.
The battle for St. Vith began in the early hours of December 18th when the 62nd Volksgrenadier Division launched a fierce assault on the town. German troops advanced to within 500 meters of their objective and managed to take control of the hills near Wallerode. Several kilometers away, Peiper’s column continued its advance, defeating American forces in Stavelot with little resistance.
Peiper’s troops advanced toward Trois-Ponts, but their progress was halted when a small group of US engineers blew up the bridge over the Amblève River. A squadron of P-51 Mustangs then located the German column and destroyed 10 of its tanks. On the night of December 18th, the US 9th Armored Division faced off against the 2nd Panzer Division, losing all of its tanks one after another.
On December 19th, German forces took control of Schnee Eifel, and the three divisions that had attacked St. Vith annihilated two US infantry regiments. Peiper’s group occupied the town of Schönenberg, capturing 284 American prisoners. On December 20th, due to a critical fuel shortage, Kampfgruppe Peiper was forced to halt, allowing the US 82nd Airborne Division to retreat deeper into St. Vith.
On December 21st, the Germans launched an assault from the northwest against St. Vith. After defeating three M10 tanks, they took Breitfeld and advanced to the town’s entrance. The Americans were forced to reduce their defensive perimeter to a narrow strip within the ruins of St. Vith. Further south, the 18th Volksgrenadier Division wiped out the last remnants of the US 106th Infantry Division, capturing over 10,000 American soldiers.
On December 23rd, King Tiger and Panther tanks launched a direct assault on St. Vith, wiping out the last remaining US Shermans. The morning brought the collapse of the final American resistance, allowing German forces to enter St. Vith. The US 7th Armored Division was completely wiped out, and the 9th Armored Division suffered heavy losses. The casualties were enormous: over 14,000 soldiers, including 3,397 killed or wounded and 10,000 captured.
With the fall of St. Vith, the town of Bastogne was now completely isolated, trapping the US 101st Airborne Division within it. Bastogne would become the final obstacle between the German forces and the Meuse River. On December 24th, an unexpected sunny day took the Germans by surprise, allowing Allied aviation to take off and attack German supply lines. US C-47 Dakota planes carried out more than 3,000 flights to drop supplies to the 101st Airborne Division.
On December 25th, the German Fifth Panzer Army resumed its attack on Bastogne. However, the German soldiers were caught off guard by the fierce fire from American artillery and bazookas. Although German troops managed to penetrate some streets of Bastogne, the American resistance repelled them. In retaliation, the Luftwaffe carried out an intense bombing over the city, causing numerous casualties.
While the battle of Bastogne continued, other fronts in the Ardennes saw intense fighting. The German 6th Panzer Army managed to take Laroche. On December 26th, the 2nd Panzer Division captured the towns of Rochefort and Cell, near the Meuse River, just before the German tanks ran out of fuel. The furthest position reached by German forces was Foy-Notre-Dame, marking an advance of 100 km into the interior of Belgium.
Patton’s Third Army advanced rapidly toward Bastogne, smashing through everything in its path. However, its progress was slowed by barricades and ambushes by German paratroopers. Despite these difficulties, Patton’s advance had a positive moral effect on the besieged forces. Patton’s troops finally broke the siege at 16:50 on December 31st, though the battle of Bastogne continued in the following days.
Frustrated by the failure of the German offensive, Hitler ordered a general withdrawal to the Siegfried Line. On December 31st, the US Army regained full control of Bastogne and one-third of the Ardennes. The Ardennes offensive cost Germany 80,000 men and exhausted a significant portion of the country’s fuel reserves. Hitler refused to accept that the Battle of the Ardennes had been a failure.
Operation Bodenplatte was an extreme measure devised by Hitler in case the offensive failed. On the night of December 31st, Luftwaffe pilots received strict orders to avoid New Year’s Eve celebrations. The next morning, more than 900 Luftwaffe aircraft took off and headed toward France, Belgium, the Netherlands, and Luxembourg. The operation resulted in a tactical victory for the Germans, but a severe strategic defeat, as the Luftwaffe was unable to replace its losses.
As January 1945 progressed, the US Army maintained the initiative and began pushing the Germans back toward their own border. German forces suffered heavy casualties and were forced to withdraw units such as the Sixth SS Panzer Army, which was sent to the Eastern Front. Despite increasing pressure, the German army continued to offer resistance, with some notable victories, but these were short-lived.
On January 28th, 1945, the German army completely abandoned Belgium and Luxembourg, marking the end of the Battle of the Ardennes. The operation, though initially successful in terms of penetration, ended up being a total failure, exhausting the last reserves of the Wehrmacht and irreparably weakening Germany’s ability to resist the Allied advance.
