Liberation of France (Second World War)

The Battle of the Belfort Gap was a decisive operation conducted by the French 1st Army to open access to Alsace in November 1944. Across difficult terrain combining mountains, forests, and fortified positions, French troops managed to break through the German lines through the famous 'gap,' a natural axis between the Vosges and the Jura. This victory marked a major strategic advance and paved the way for the liberation of Mulhouse and Strasbourg.

On 15 August 1944, the Allies landed on the beaches of Provence, with a central role entrusted to the French 1st Army. French troops, notably from North Africa, quickly seized Toulon and Marseille and advanced up the Rhône valley. This coordinated operation opened a second front in France and liberated a large part of the territory in less than a month.

The liberation of Lyon, former capital of the Resistance, was a crucial step in the reconquest of French territory. After the breakthrough at Montélimar, French troops entered Lyon on 2 and 3 September 1944. The FFI, already in insurrection for several days, confronted the last pockets of German and militia resistance. The population massively supported the resistance fighters' action, while the Germans fled or surrendered. Lyon was liberated without major destruction thanks to coordination between the FFI and regular French forces.

The liberation of Marseille was carried out swiftly by the 3rd DIA and local FFI forces. While the Germans attempted to sabotage the port infrastructure, French troops and resistance fighters quickly seized the city's strategic points. After a week of fierce fighting, the German army surrendered. Marseille was liberated without its port being entirely destroyed, which would prove crucial for the rest of the war.

The Battle of Montélimar was a key engagement in the advance up the Rhône valley. After the landing in Provence, Allied forces sought to intercept the retreat of the German 19th Army. The strategic bottleneck of Montélimar, controlling the north-south axis of the valley, became the focus of a series of fierce engagements between the Franco-American Task Force Butler and German units. Although the Germans managed to evacuate part of their forces, the battle severely disorganized their retreat and inflicted considerable losses.

The Battle of Mulhouse pitted French forces of the 1st Army against a German garrison entrenched in the industrial city of Alsace. The objective was to consolidate the advance begun after the breakthrough of the Belfort Gap and secure access to the Rhine. The battle was brief but intense, with violent street fighting, particularly around the industrial facilities. The city was liberated on 24 November.

The liberation of Strasbourg, the capital of Alsace, was a strategic and highly symbolic objective for French forces. General Leclerc's 2nd Armored Division, detached northward after its advance from Paris, entered Strasbourg on 23 November 1944, despite pockets of German resistance. The capture of the city represented a strong act of sovereignty and revenge for the German annexation of 1940.

Following the landing in Provence, French forces were tasked with liberating Toulon. The fighting was intense in this heavily fortified city. French units attacked simultaneously from the north and east, advancing street by street despite mortar fire, booby traps, and destruction. After six days of combat, the German garrison surrendered. Toulon was entirely liberated on 26 August.

The Battle of the Colmar Pocket is one of the last major operations of the Liberation on French soil. It aimed to dislodge German forces entrenched in the Haut-Rhin, who still held the entire Colmar plain. Led by General de Lattre, the French 1st Army conducted intense fighting under extreme winter conditions. After nearly three weeks of fierce struggle, Colmar was liberated on 2 February 1945.
