Below is a summary of ETO front line organization on 4 April 1945, including army groups, armies and corps.
ETO Overview, late March and early April 1945:
  • By the last week in March, combat in the European Theater had moved east beyond the Rhine River.
  • On 28 March, General Dwight Eisenhower, the supreme commander of Allied forces in the European Theater, addressed his plans for the ETO advance eastward through central Germany. Dashing General Montgomery's expectations, the main effort would be from Bradley's US 12th Army Group rather than Montgomery's British 21st Army Group.
  • On 1 April, US forces achieved a major goal, encircling the Ruhr industrial area.
  • On 4 April, the US Ninth Army was transferred from the British 21st Army Group back to the US 12th Army Group.

The ETO Situation Map,  4 April 1945
In the 12th Army Group's 4 April 1945 situation map, note the conspicuous Ruhr Pocket in the upper middle.

Some US Ninth and First Army units were charged with reducing the Ruhr Pocket. Most other Allied ground forces were past the Rhine River advancing in a generally eastward direction into Germany.
