In 1941, Doña Ana, New Mexico, and its surrounding areas were influenced by the rapid expansion of military activity due to the United States' preparation for World War II. While Doña Ana itself did not host a military post in 1941, significant military developments in the region impacted the area:

1. Fort Bliss Expansion

• Fort Bliss, headquartered in El Paso, Texas (about 40 miles south of Doña Ana), expanded significantly during this time to support the war effort. Training grounds for troops extended into southern New Mexico, including areas near Doña Ana.
• The region was used for military exercises and maneuvers, with Doña Ana serving as a logistical waypoint due to its proximity to training areas.

2. Doña Ana Range

• By the early 1940s, the Doña Ana Range Complex was established as part of Fort Bliss's training and testing areas. This range was utilized for artillery training and military exercises.
• It became an integral part of Fort Bliss's operations during the war and continues to be a part of the military infrastructure.

3. White Sands Proving Ground (Later White Sands Missile Range)

• Though White Sands Proving Ground officially opened in 1945, plans and surveys for establishing a large military testing site in the region were being developed during the early 1940s.
• The establishment of this site drastically shaped the area's military significance in subsequent years.

4. National Defense and Infrastructure

• The U.S. government's focus on military preparedness during 1941 brought federal resources and infrastructure to the region. Railroads, roads, and other facilities in Doña Ana and nearby areas were upgraded to support the movement of troops and supplies.
