Western Allied invasion of Germany

Western Allied invasion of Germany. The Western Allied invasion of Germany, codenamed Operation Plunder and Operation Undertone, was the final major campaign of the European theatre of World War II. Launched in March 1945, the offensive saw the United States, United Kingdom, Canada, and France cross the Rhine and advance deep into the heart of the Third Reich. The operation culminated in the link-up with the Red Army along the Elbe River and the unconditional surrender of Nazi Germany, ending the war in Europe.

Background and planning

Following the conclusion of the Battle of the Bulge and the subsequent Allied advance from Paris to the Rhine, the Supreme Headquarters Allied Expeditionary Force under Dwight D. Eisenhower planned the final assault into Germany. The strategic objective was to destroy the remaining Wehrmacht forces west of the Rhine, secure crossings over the river, and advance to meet the Soviet forces advancing from the east. Key to the plan was the 21st Army Group under Bernard Montgomery, which would launch a major assault crossing in the north, while the 12th Army Group under Omar Bradley and the 6th Army Group under Jacob L. Devers would conduct supporting operations further south. The planners anticipated fierce resistance from units like Army Group B commanded by Walter Model.

Invasion and initial operations

The invasion commenced on the night of 22-23 March 1945 with Operation Plunder, the massive Rhine crossing by Montgomery's forces near Wesel, supported by the airborne Operation Varsity. Simultaneously, elements of Bradley's command, including the First United States Army, had already seized an intact bridge at Remagen during the Battle of Remagen, establishing a critical bridgehead. To the south, Operation Undertone was launched by Devers' Seventh United States Army and the French First Army under Jean de Lattre de Tassigny, breaking through the Siegfried Line and crossing the Rhine near Worms. These operations successfully breached Germany's last major natural defensive barrier.

Advance to the Elbe and meeting with Soviet forces

Exploiting the bridgeheads, Allied forces fanned out across Westphalia, Hesse, and Bavaria in a rapid advance. The Third United States Army under George S. Patton drove through central Germany, while the First United States Army encircled and reduced the Ruhr Pocket, trapping Army Group B and capturing over 300,000 German soldiers. By mid-April, Allied spearheads reached the Elbe River. On 25 April 1945, forward elements of the U.S. 69th Infantry Division met troops of the 58th Guards Rifle Division of the Red Army at Torgau, a historic link-up that physically split the remnants of the Third Reich.

Final offensives and German surrender

In the final weeks, Allied armies cleared remaining pockets of resistance. The British Second Army advanced into northern Germany, capturing cities like Bremen and Hamburg. The U.S. forces pushed into Czechoslovakia and Austria, while the French First Army operated in the southwest near the Swiss border. As the Battle of Berlin raged, the German government's command structure collapsed following the death of Adolf Hitler on 30 April. Grand Admiral Karl Dönitz, as Hitler's successor, authorized the surrender. The unconditional surrender of all German forces was signed at Reims on 7 May and ratified in Berlin on 8 May 1945, known as Victory in Europe Day.

Aftermath and consequences

The invasion's success led to the complete military and political collapse of Nazi Germany. The subsequent Allied occupation of Germany was formalized into zones administered by the United States, United Kingdom, France, and the Soviet Union, setting the stage for the Cold War and the eventual division of Germany. The campaign also revealed the full horrors of the Nazi concentration camps such as Buchenwald and Dachau, liberated by advancing American troops. The end of hostilities in Europe allowed the Allies to fully turn their resources toward the ongoing Pacific War against the Empire of Japan.
