Alsace-Lorraine, 1945 - Background

The US 6th Army Group, consisting of the US Seventh Army and the French First Army, had liberated most of Alsace in November 1944. However, the German 19th Army remained in southern Alsace in the Colmar Pocket.
To the north, in the Ardennes in December 1944, the German Wehrmacht launched the massive counteroffensive known as the Battle of the Bulge. The remainder of the ETO front went into a defensive posture.

Alsace-Lorraine, 1945 - Overview

1 January 1945: Beginning of Operation Nordwind, a German counteroffensive in northeast Alsace-Lorraine. The seized territory remained largely in German hands until mid-March.
20 January - 9 February 1945: French and US forces eliminated the Colmar Pocket, the last German presence in southern Alsace.
February & early March 1945: Seventh Army forces in the Sarre Rive and Bitche areas of extreme northern Lorraine engaged in limited offensives.
March 1945: In Operation Undertone, as part of the 1945 ETO advance to the Rhine, the Seventh Army drove north through the remaining German-occupied areas of Alsace and Lorraine, penetrated the Siegfried Line in the Saar area, and wheeled northeast to the Rhine. Third Army had already cleared the area behind the Siegfried Line. Elements of the French First Army advanced north near the Rhine River.

The accompanying map shows both the land lost to Germany during Nordwind and the land gained from Germany by the elimination of the Colmar Pocket.

Thus, at the end of January 1945, the US 6th Army Group was on the the defensive in northern Alsace and on the offensive in southern Alsace.
