As the 12th advanced through Germany in 1945, it controlled four field armies: US First Army;US Third Army;US Ninth Army and US Fifteenth Army.
This was to have been the northern part of a pincer movement, with the US Ninth Army moving northwards towards Dusseldorf and Krefeld (Operation Grenade), to clear the west bank of the Rhine, north of Cologne.
Canadian First Army wheeled left and liberated northern Holland, British Second Army occupied much of north-west Germany and liberated Denmark, and US Ninth Army formed the northern arm of the encirclement of German forces in the Ruhr pocket and, on 4 April, reverted to Bradley's 12thArmyGroup.
