In the early 1940s, the town underwent a dramatic change. One month after the attack on
Pearl Harbor, the U. S. government chose Oak Hill and the surrounding region as the site for
Camp Swift, a massive
Army training camp and German
prisoner-of-war camp. Residents and business owners were paid a lump sum for their land, and moved to neighboring towns such as Bastrop and Elgin. Some buildings were torn down; some were sold and moved, or sold for materials. Others were used as training targets. At the time, Camp Swift was Texas' largest army training and
transshipment camp. It covered nearly 56,000 acres and had 2,750 buildings designed to hold 44,000 troops and about 4,000 prisoners of war. At its peak during
World War II, the camp housed 90,000 troops simultaneously. Camp Swift also brought civilian jobs in transportation, defense, and manufacturing. Following the war, Camp Swift was downsized, with barracks and buildings sold as scrap for $5 a truckload. The government had promised former residents they could buy back their property at war's end. Some land was returned to the original owners, but the community was not rebuilt. Because the land's value had skyrocketed, many could not afford to return. The town name disappeared from county highway maps in the 1980s. ==Today==
