6th Army Group was a major Allied formation during the final year of the Second World War in the European Theater. Activated in the summer of 1944, it was a combined force of American and French armies operating under the command of SHAEF. The group played a crucial role in the liberation of southern France and the subsequent drive into Germany, linking up with other Allied forces to crush Nazi Germany.

Formation and organization

The group was formally activated on 1 August 1944 at Naples, Italy, under the command of Lieutenant General Jacob L. Devers. It was originally designated as the "Southern Group of Armies" and was created to command the U.S. Seventh Army and the French First Army for the impending Operation Dragoon, the Allied invasion of southern France. Its headquarters was established under the auspices of Allied Forces Headquarters in the Mediterranean Theater, before transferring to continental Europe. The formation represented a significant multinational command, integrating the logistical and combat power of two major Allied nations under a single headquarters.

Operational history

The group's operational history began with the successful execution of Operation Dragoon on 15 August 1944, landing forces between Toulon and Cannes. Following a rapid advance up the Rhône valley, its forces linked with elements of General George S. Patton's U.S. Third Army, part of 12th Army Group, near Dijon in mid-September. This connection created a continuous frontline from the North Sea to the Mediterranean Sea. Subsequently, the group fought through the Vosges mountains, liberated Strasbourg in November 1944, and endured a difficult winter campaign reducing the Colmar Pocket in Alsace.

Command structure

Lieutenant General Jacob L. Devers served as the group's commanding general for its entire existence. His deputy commander was the French General Jean de Lattre de Tassigny, who also commanded the French First Army. The chief of staff was American Major General David G. Barr. The group reported directly to Supreme Allied Commander Dwight D. Eisenhower at SHAEF after being transferred from the Mediterranean Theater to the European Theater of Operations in September 1944. This placed it alongside 12th Army Group and 21st Army Group under Eisenhower's unified command.

Component units

The group's primary combat formations were the U.S. Seventh Army, commanded by General Alexander Patch, and the French First Army, commanded by General Jean de Lattre de Tassigny. Key subordinate corps included the U.S. VI Corps under Major General Lucian Truscott and later Major General Edward H. Brooks, the U.S. XV Corps under Major General Wade H. Haislip, and the French II Corps. These corps controlled numerous infantry and armored divisions from both nations throughout the campaign.

Campaigns and battles

The group was central to several major campaigns in 1944–1945. Its first and defining operation was Operation Dragoon, the invasion of Provence. This was followed by the Rhône valley campaign and the Vosges campaign. One of its most difficult engagements was the Battle of the Colmar Pocket in early 1945, a protracted struggle to eliminate a German salient west of the Rhine. In the spring, the group conducted its own crossing of the Rhine during the Rhine Campaign in the Worms area, part of the broader Invasion of Germany. It then advanced through Bavaria, capturing cities like Nuremberg and Munich, and linked with U.S. Fifth Army forces from Italy in the Austrian Alps at Brenner Pass.

Disbandment and legacy

Following the German surrender in May 1945, the group assumed occupation duties in the southern sector of Germany. It was inactivated on 10 July 1945, with its American components absorbed into the U.S. occupation forces. The group's legacy is that of a highly effective multinational command that executed a large-scale amphibious assault and a relentless offensive from the Mediterranean coast to the heart of Germany. Its success in Operation Dragoon provided critical additional ports and pressure on German forces, contributing significantly to the Allied victory in Western Europe.
