Operation Queen was not able to meet its sophisticated goals. At the beginning of the offensive, Allied planners envisioned for the offensive to be just a staging point for a deep penetration over the Rur into Germany to the Rhine. After one month of heavy fighting the Americans had barely made it to the Rur. No bridgehead over the river had been made, the Germans still held some portions west of the river and the important Rur dams were still in German hands, threatening any further offensive operations. Even without knowing the upcoming German offensive, Allied planners estimated the earliest date for a large thrust into Germany for mid-January.
