Eliminating the Colmar Pocket, January-February 1945
|
Allied planners hoped to eliminate the Colmar Pocket while the ground remained frozen. Thus, on 20 January 1945 while Operation Nordwind continued in northern Alsace-Lorraine, combat began to eliminate the pocket. Eventually three Allied corps were involved:
On 5 February the Colmar Pocket was surrounded by French and US troops and on 9 February the pocket was cleared. Surviving German soldiers retreated across the Rhine River, destroying the remaining bridges. The entire left bank of the upper Rhine, from Strasbourg upstream to the Swiss border, was now in Allied hands. ETO divisions tied up minding the pocket could now be used elsewhere. |

During Operation Undertone, the Seventh Army's advance on the Siegfried Line in mid-March 1945, XXI Corps, with a different complement of divisions, was on the Seventh Army's left flank.
