After World War II, many of the officials of the German rocket program -- including leader Wernher von Braun -- were brought to the United States to develop missiles for the U.S. Army. They initially worked at Fort Bliss, Texas. However, the group was relocated in 1950 to Redstone Arsenal in Huntsville, Alabama. The facility was transferred to NASA in 1960 and renamed the Marshall Space Flight Center. Von Braun served as the facility's first director until 1970. The center is particularly known for launch vehicle development (Mercury-Redstone, Apollo-Saturn, Shuttle) and space station operations (Skylab, ISS).
Why was Redstone Arsenal particularly chosen for the Army rocket group? There seem to be plenty of other potential choices:
Wikipedia suggests that Redstone was a natural choice because it was involved in "the production and storage of ordnance shells" during WWII. However, there were plenty of other munitions plants throughout the U.S., so why not these other sites? In particular, Wikipedia describes Thiokol having to move operations from Maryland to Redstone Arsenal.
Von Braun's group initially launched missiles from the White Sands Missile Range in New Mexico. As the largest U.S. Army facility, it has plenty of space which could have been used for R&D.
Development for the White Sands missiles occurred across the state line, at Fort Bliss, Texas. Von Braun's group started there, and arguably could have stayed there. As the second largest U.S. Army facility, it also has plenty of available space.
Cape Canaveral in Florida may at first seem like a logical choice. However, it was never owned by the Army: by the Navy as Banana River Naval Air Station (1940-1948), by the Air Force (1948-2020), and by the Space Force (2020-current).
Kennedy Space Center did not break ground until 1962, nor was it ever involved with Army missile development.
I'm looking for an answer backed by an authoritative source.
