When the United States entered World War II, the 29th Infantry moved to Iceland, where it defended the rocky coastline until shipped to England in preparation for the invasion of Europe. In December, 1944 the regiment deployed to France where it provided security to the "Red Ball Express", the supply route which kept the armored thrust rolling into Germany. During the "Battle of the Bulge", the regiment secured and defended river crossings along the Meuse River in the vicinity of Namur and Liege, Belgium. The Regiment saw heavy combat near Jemelle and Rochefore, Belgium and was then deactivated in October, 1946.
