21st Army Group

During World War II, the British Army formed a powerful headquarters unit known as the 21st Army Group. Like a skilled conductor, this formation controlled two field armies and several supporting units, including the British Second Army and the First Canadian Army, during the Western Allied invasion of Europe.

Established in London during July 1943, under the command of Supreme Headquarters Allied Expeditionary Force (SHAEF), the 21st Army Group was an important force in the European Theatre, operating in Northern France, Luxembourg, Belgium, the Netherlands, and Germany from June 1944 until August 1945.

With a strength of over a million officers and men, the 21st Army Group was well-equipped with tanks, artillery pieces, and aircraft. In fact, it had 9,248 tanks, 6,584 artillery pieces, and 1,600 aircraft at its disposal, including the powerful 2nd Tactical Air Force.

The 21st Army Group's tactical proficiency and strategic vision was evident in the range of field armies and corps it had under its command. These included British, Canadian, American, and Polish forces, which were attached to the group at various times during its existence.

The 21st Army Group's role in Operation Overlord, the Western Allied invasion of Europe, was crucial. Its forces helped to liberate large parts of Northern Europe from Nazi occupation, paving the way for the eventual Allied victory.

Following its successful operations, the 21st Army Group was renamed the British Army of the Rhine (BAOR) in August 1945. It continued to play an important role in post-war Europe, helping to maintain stability and security in the region.

In conclusion, the 21st Army Group was a vital military formation that played a crucial role in the Allied victory during World War II. Its tactical proficiency and strategic vision, combined with its impressive strength, helped to liberate Northern Europe from Nazi occupation and establish peace and stability in the region.

Western European theatre

In the history of World War II, the 21st Army Group played a crucial role in the Western European theater, commanding ground forces in Operation Overlord alongside the US First Army and British Second Army. Despite heavy resistance in Normandy, British and Canadian troops drew in most of the available German reinforcements, enabling the American breakout at the western end of the beachhead. Following the German attack toward Mortain and an advance by the 21st Army Group, the Germans were nearly surrounded in the Falaise pocket and ultimately retreated towards the Low Countries.

The 21st Army Group was responsible for securing ports upon which Allied supply depended and overrunning German V-1 and V-2 launching sites along the coasts of Western France and Belgium. By August 29th, the Germans had withdrawn across the Seine River without their heavy equipment. The advance was so rapid that Antwerp, Belgium, was captured undefended on September 4th, and the port facilities were cleared of German defenders in the following days. By mid-September, elements of 21st Army Group had reached the Dutch border but were halted due to lack of supplies and flooding caused by German demolition of Dutch dikes.

The group played a key role in Operation Market Garden, which aimed to cross the Rhine River and end the war in 1944. The operation was staged in the Netherlands with the airborne troops of the US 82nd and 101st Airborne Divisions and the British 1st Airborne Division. Despite initial successes, the operation ultimately failed to achieve its objectives due to German resistance.

In conclusion, the 21st Army Group played a significant role in World War II's Western European theater. The group's efforts in Normandy and the subsequent pursuit through Northern France and Belgium helped to weaken German forces, while their advances into the Low Countries and involvement in Operation Market Garden demonstrated their strategic importance in the war effort. Despite setbacks and challenges, the 21st Army Group remained a powerful force that contributed to the eventual Allied victory.

British Army of the Rhine

The end of a war is often thought of as a time of celebration, of joy and of relief. But for the soldiers of the 21st Army Group, the conclusion of World War II brought with it a new set of challenges, as they found themselves tasked with overseeing the occupation of Germany.

This was no easy feat, and it required the conversion of the 21st Army Group into the headquarters for the British occupation zone in Germany. The soldiers who had fought bravely and tirelessly on the front lines were now being called upon to play a different kind of role, one that required just as much skill and determination, but in a very different context.

It was on August 25th, 1945, that the 21st Army Group was officially renamed the British Army of the Rhine (BAOR). This new entity would go on to become the backbone of the British forces stationed in Germany throughout the Cold War, a time when tensions between East and West were at their highest and the threat of nuclear war loomed large.

The BAOR was a force to be reckoned with, comprising some of the finest soldiers and military minds in the world. They were tasked with keeping the peace and maintaining order in a country that had been torn apart by war and whose people were still reeling from the trauma of the past few years.

The soldiers of the BAOR were no strangers to hardship and adversity, and they faced their new mission with the same determination and grit that had served them so well in the war. They had to deal with everything from rationing and shortages to the ever-present threat of sabotage and terrorism from the remnants of the defeated German army.

But despite these challenges, the soldiers of the BAOR persevered, working tirelessly to rebuild a broken country and to lay the foundations for a better future. They were not just soldiers, but also diplomats, teachers, builders and ambassadors, working to build bridges between former enemies and to forge a path towards a more peaceful world.

Today, the legacy of the BAOR lives on, a testament to the courage and determination of the soldiers who served in its ranks. It serves as a reminder of the power of resilience and the importance of working together towards a common goal, even in the face of seemingly insurmountable obstacles. The BAOR may be a thing of the past, but its impact will be felt for generations to come, a shining example of what can be achieved when people come together to build a better world.

Order of battle

During World War II, the 21st Army Group played a vital role in the Allied victory over Germany. The group consisted of several armies, including the British Second Army and the First Canadian Army, as well as small units from Poland, Belgium, the Netherlands, and Czechoslovakia. The group also had American units attached at various times.

The British Second Army was led by General Sir M. Dempsey, while General H. Crerar led the First Canadian Army. Both armies were made up of a mix of nationalities, with the British Second Army including units from the UK, Poland, and the Netherlands, while the First Canadian Army had both Canadian and British units.

The British Second Army was divided into three corps: VIII Corps, XII Corps, and XXX Corps. VIII Corps was led by General R. O'Connor and included the Guards Armoured Division, the 3rd Infantry Division, the 5th Infantry Division, and the 15th (Scottish) Infantry Division. XII Corps, led by General N. Ritchie, included the 11th Armoured Division, the 53rd (Welsh) Infantry Division, and the 59th (Staffordshire) Infantry Division. XXX Corps, led by General G. C. Bucknall, consisted of the 7th Armoured Division, the 43rd (Wessex) Infantry Division, the 51st (Highland) Division, the 50th (Northumbrian) Infantry Division, and the 52nd (Lowland) Division.

The First Canadian Army was divided into two corps: II Canadian Corps and I Corps. II Canadian Corps, led by General G. Simonds, included the 2nd Canadian Division, the 3rd Canadian Division, and the 4th Canadian (Armoured) Division. I Corps, led by General G. Crocker, included the 1st Armoured Division from Poland. The I Canadian Corps arrived in March 1945 from Italy and included the 1st Canadian Division, the 5th Canadian (Armoured) Division, and the 49th (West Riding) Infantry Division.

Throughout its existence, the 21st Army Group had American units attached at various times. During Operation Market Garden, two U.S. airborne divisions, the 101st and 82nd, were deployed as part of the First Allied Airborne Army. During Operation Pheasant, the US 104th Infantry Division reinforced I British corps. During the Battle of the Bulge, the U.S. First and Ninth Armies on the north face of the bulge came under the control of 21st Army Group. The U.S. Ninth Army remained part of 21st Army Group during the drive to the Rhine, the Rhine crossings, and the battle of the Ruhr Pocket. The U.S. 17th Airborne Division also took part in the Rhine crossings as part of Operation Varsity. Finally, during Operation Clipper, the U.S. 84th Infantry Division was temporarily attached to British XXX Corps.

Overall, the 21st Army Group played a crucial role in the Allied victory over Germany during World War II. Its diverse makeup of nationalities and its ability to coordinate with American units made it a formidable force on the battlefield. Its legacy continued with the British Army of the Rhine, which formed the nucleus of the British forces stationed in Germany throughout the Cold War.

Commanders

The 21st Army Group was one of the most crucial military formations of the Second World War, and the commanders who led it played an essential role in the success of the Allied forces. The group was commanded by two distinguished British generals, who led the troops through some of the most intense battles of the war.

The first commander of the 21st Army Group was General Bernard Paget, who served from June to December 1943. Although his tenure was brief, Paget was instrumental in the formation and training of the group, laying the groundwork for its success in the later years of the war. Under his leadership, the troops underwent rigorous training, and their readiness for combat was significantly improved.

In January 1944, General Bernard Montgomery took over the command of the 21st Army Group from Paget. Montgomery was a seasoned veteran of the war, having previously led British forces in North Africa and Italy. He was a brilliant strategist and a skilled commander, and his leadership was critical to the success of the group.

Montgomery led the 21st Army Group through some of the most challenging battles of the war, including the Battle of Normandy and the Battle of the Bulge. His ability to inspire and motivate the troops was unmatched, and his tactical genius was crucial in achieving victory in these battles. Montgomery was known for his meticulous planning and attention to detail, and he was always willing to take calculated risks to achieve his objectives.

Under Montgomery's leadership, the 21st Army Group played a crucial role in the Allied victory in Europe. The group liberated Paris, played a key role in the Battle of the Scheldt, and helped to break the German line at the Rhine. Montgomery's success as a commander was recognized when he was made a Viscount and awarded the Order of the Garter, the highest honor in the British honours system.

In conclusion, the commanders of the 21st Army Group played an essential role in the Allied victory in Europe. General Bernard Paget laid the foundation for the group's success, while General Bernard Montgomery's leadership and tactical genius led the group to some of its most significant victories. Their contributions to the Allied war effort will always be remembered as a testament to their skill, courage, and dedication to the cause of freedom.
