The
Colmar Pocket (; ) was the area held in central
Alsace,
France by the
German Nineteenth Army from November 1944 – February 1945, against the
U.S. 6th Army Group during
World War II. It was formed when 6th AG liberated southern and northern Alsace and adjacent eastern
Lorraine, but could not clear central Alsace. During
Operation Nordwind in December 1944, the 19th Army attacked north out of the Pocket in support of other German forces attacking south from the
Saar into northern Alsace. In late January and early February 1945, the
French First Army (reinforced by the
U.S. XXI Corps) cleared the Pocket of German forces.
