Aachen, Germany October 20, 1944 As the city becomes darkened by a pall of smoke from exploding shell bursts, Yank artillerymen move their gun into position on the corner of Bismarck St. in Aachen, as street-to-street fighting continues in the besieged German city. It was announced today that the American first army had completed the mop-up of Aachen, leaving Gen. Hodges army free to continue its drive eastward over the Cologne plain.
