The Battle of the Bulge
OwO, also called the Unternehmen Wacht Am Rhein by the Germans and the Ardennes Counteroffensive by the Allies, was a major Nazi offensive on the allied forces near the river Rhine as a last-ditch effort to attempt to blitzkrieg their way back to sea, trapping the Allies. The offensive was eventually halted and repelled.
In desperation, Nazi Germanyball planned to conduct a major offensive, literally throwing everything they could spare at the Allies. The initial plan was to use blitzkried tactics and encircle the Allies. The Battle of the Bulge began with a massive 90-minute-long German artillary barrage across the 130-kilometer front. Heavy snowstorms also consumed parts of the Ardennes, grounding and disabling Allied air power. Eventually, the Germans managed to push 80 km into the Allied front, before overstretching their supply lines.
The Failure of Germany
However, just about every army in the area turned to the Bulge and launched a massive relief operation against the overstretched Germans. The weather cleared and the Allied Air Power Germany feared forced the Germans to retreat and the Bulge was filled back in by Allied soldiers. The Battle of the Bulge had been a major disaster, as 90000 men were either dead or captured and with the rest of the forces occupied with the Soviets, all the Germans could do in the Western Front was defend.
