In December 1944, Koch warned Patton that intelligence indicators pointed to an imminent large-scale German offensive against First Army in the Ardennes, to Third Army's north. Though G-2s at other commands believed Germany incapable of a large scale offensive, Patton heeded Koch's warning and incorporated emergency measures for aiding First Army into his subsequent plans. As a result, when Germany launched the offensive that became known as the Battle of the Bulge, Third Army was prepared to reorient from attacking on a west to east axis to advance north towards First Army and immediately enter combat. Third Army's effort helped end the German offensive and left the Allies prepared to enter Germany in the spring of 1945.
