The 9th Armored Division was cited for extraordinary heroism and gallantry in combat in the vicinity of Waldbillig and Savelborn, Luxembourg from 16–22 December 1944 during which they repulsed constant and determined attacks by an entire German division. Outnumbered five to one, with its infantry rifle companies surrounded for most of the time, clerks, cooks, mechanics, drivers and others manned the final defensive line. Supported by the outstandingly responsive and accurate fire of its artillery battalion, this widely dispersed force stopped every attack for six days until its surrounded infantry were ordered to fight their way back to them. This staunch defense disrupted the precise German attack schedule and thus gave time for the United States III and XII Corps to assemble unhindered and then launch the coordinated attack which raised the siege of Bastogne and contributed to saving much of Luxembourg and its capital from another German invasion. They were awarded the Presidential Unit Citation for their heroism.
