Battle of the Colmar Pocket

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.

While most of Alsace had been liberated, the Colmar pocket remained firmly held by the Wehrmacht, constituting a threat to Allied lines and a symbolic affront to territorial control. De Gaulle insisted that it be the French 1st Army that led the liberation. The fighting took place in freezing weather, on flat, flooded terrain, with fortified villages fiercely defended by German troops.

The 1st Army launched coordinated attacks from the north (Mulhouse) and the south (toward Turckheim), supported by artillery and armor. Advances were made village by village, with violent street fighting at Colmar, Ingersheim, Neuf-Brisach, and Jebsheim. The Germans used well-entrenched positions and difficult terrain to slow the advance. Close cooperation with the US 3rd Infantry Division was crucial in breaking through certain lines.

The victory in the Colmar pocket marked the complete liberation of metropolitan French territory. It strengthened the prestige of the reconstituted French army and proved its ability to conduct large-scale operations. Strategically, it secured the left bank of the Rhine and opened the way to the invasion of Germany via the Black Forest. The battle is one of the costliest for the French army since the 1940 campaign of France.
