World War II Operation Dragoon Overview (1944)

Operation Dragoon was conducted from August 15 to September 14, 1944, during World War II (1939-1945).

First proposed by General George Marshall, Chief of Staff of the US Army, and intended to coincide with Operation Overlord, the landings in Normandy, the attack was put off due to slower than expected progress in Italy as well as a lack of landing craft. Further delays ensued after the difficult amphibious landings at Anzio in January 1944. As a result, its execution was pushed back to August 1944. Though highly supported by Supreme Allied Commander General Dwight D. Eisenhower, the operation was bitterly opposed by British Prime Minister Winston Churchill. Seeing it as a waste of resources, he favored renewing the offensive in Italy or landing in the Balkans. Looking ahead to the postwar world, Churchill wished to conduct offensives that would slow the progress of the Soviet Red Army while also hurting the German war effort. These views were also shared by some in the American high command, such as Lieutenant General Mark Clark, who advocated for striking across the Adriatic Sea into the Balkans. For the opposite reasons, Russian leader Joseph Stalin supported Operation Dragoon and endorsed it at the 1943 Tehran Conference. Standing firm, Eisenhower argued that Operation Dragoon would draw German forces away from Allied advance in the north as well as would provide two badly needed ports, Marseille and Toulon, for landing supplies. The Allied Plan Pushing forward, the final plan for Operation Dragoon was approved on July 14, 1944. Overseen by Lieutenant General Jacob Devers 6th Army Group, the invasion was to be spearheaded by Major General Alexander Patchs US Seventh Army which would be followed ashore by General Jean de Lattre de Tassignys French Army B. Learning from experiences in Normandy, planners selected landing areas that were devoid of enemy-controlled high ground. Choosing the Var coast east of Toulon, they designated three primary landing beaches: Alpha (Cavalaire-sur-Mer), Delta (Saint-Tropez), and Camel (Saint-Raphaà «l). To further aid the troops coming ashore, plans called for a large airborne force to land inland to secure the high ground behind the beaches. While these operations moved forward, commando teams were tasked with liberating several islands along the coast. The main landings were assigned respectively to the 3rd, 45th, and 36th Infantry Divisions from Major General Lucian Truscotts VI Corps with assistance from the 1st French Armoured Division. A veteran and skilled combat commander, Truscott had played a key role in rescuing Allied fortunes at Anzio earlier in the year. To support the landings, Major General Robert T. Fredericks 1st Airborne Task Force was to drop around Le Muy, approximately halfway between Draguignan and Saint-Raphaà «l. After securing the town, the airborne was tasked with preventing German counterattacks against the beaches. Landing to the west, French commandos were ordered to eliminate the German batteries on Cap Nà ¨gre, while the 1st Special Service Force (Devils Brigade) captured islands offshore. At sea, Task Force 88, led by Rear Admiral T.H. Troubridge would provide air and naval gunfire support. German Preparations Long a rear area, the defense of southern France was tasked to Colonel General Johannes Blaskowitzs Army Group G. Largely stripped of its frontline forces and better equipment over the previous years, Army Group G possessed eleven divisions, four of which were dubbed static and lacked transportation to respond to an emergency. Of its units, only Lieutenant General Wend von Wietersheims 11th Panzer Division remained as an effective mobile force, though all but one of its tank battalions had been transferred north. Short on troops, Blaskowitzs command found itself stretched thin with each division along the coast responsible for 56 miles of shoreline. Lacking the manpower to reinforce Army Group G, the German high command openly discussed ordering it to pull back to a new line near Dijon. This was put on hold following the July 20 Plot against Hitler. Going Ashore Initial operations commenced on August 14 with the 1st Special Service Force landing in the ÃŽles dHyà ¨res. Overwhelming the garrisons on Port-Cros and Levant, they secured both islands. Early on August 15, Allied forces began moving towards the invasion beaches. Their efforts were aided by the work of the French Resistance which had damaged communications and transportation networks in the interior. To the west, French commandos succeeded in eliminating the batteries on Cap Nà ¨gre. Later in the morning little opposition was encountered as troops came ashore on Alpha and Delta Beaches. Many of the German forces in the area were Osttruppen, drawn from German-occupied territories, who quickly surrendered. The landings on Camel Beach proved more difficult with severe fighting on Camel Red near Saint-Raphaà «l. Though air support aided the effort, later landings were shifted to other parts of the beach. Unable to fully oppose the invasion, Blaskowitz began making preparations for the planned withdrawal north. To delay the Allies, he pulled together a mobile battle group. Numbering four regiments, this force attacked from Les Arcs towards Le Muy on the morning of August 16. Already badly outnumbered as Allied troops had been streaming ashore since the previous day, this force was nearly cut off and fell back that night. Near Saint-Raphaà «l, elements of the 148th Infantry Division also attacked but were beaten back. Advancing inland, Allied troops relieved the airborne at Le Muy the next day. Racing North With Army Group B in Normandy facing a crisis as a result of Operation Cobra which saw the Allied forces break out of the beachhead, Hitler had no choice but to approve the full withdrawal of Army Group G on the night of August 16/17. Alerted to the German intentions through Ultra radio intercepts, Devers began pushing mobile formations forward in an effort to cut off Blaskowitzs retreat. On August 18, Allied troops reached Digne while three days later the German 157th Infantry Division abandoned Grenoble, opening a gap on the German left flank. Continuing his retreat, Blaskowitz attempted to use the Rhone River to screen his movements. As American forces drove north, French troops moved along the coast and opened battles to retake Toulon and Marseille. After protracted fights, both cities were liberated on August 27. Seeking to slow the Allied advance, the 11th Panzer Division attacked toward Aix-en-Provence. This was halted and Devers and Patch soon learned of the gap on the German left. Assembling a mobile force dubbed Task Force Butler, they pushed it and the 36th Infantry Division through the opening with the goal of cutting off Blaskowitz at Montà ©limar. Stunned by this move, the German commander rushed the 11th Panzer Division to the area. Arriving, they stopped the American advance on August 24. Mounting a large-scale assault the next day, the Germans were unable to dislodge the Americans from the area. Conversely, the American forces lacked the manpower and supplies to regain the initiative. This led to a stalemate which allowed the bulk of Army Group G to escape north by August 28. Capturing Montà ©limar on August 29, Devers pushed forward VI Corps and the French II Corps in pursuit of Blaskowitz. Over the ensuing days, a series of running battles occurred as both sides moved north. Lyon was liberated on September 3 and a week later, the lead elements from Operation Dragoon united with Lieutenant General George S. Pattons US Third Army. The pursuit of Blaskowitz ended shortly thereafter when the remnants of Army Group G assumed a position in the Vosges Mountains. Aftermath In conducting Operation Dragoon, the Allies sustained around 17,000 killed and wounded while inflicting losses numbering approximately 7,000 killed, 10,000 wounded, and 130,000 captured on the Germans. Shortly after their capture, work began to repair the port facilities at Toulon and Marseille. Both were open to shipping by September 20. As the railroads running north were restored, the two ports became vital supply hubs for Allied forces in France. Though its value was debated, Operation Dragoon saw Devers and Patch clear southern France in faster than expected time while effectively gutting Army Group G.
