A is for Arlington Hall #AtoZChallenge
The A to Z Challenge asks bloggers to post 26 posts, one for each letter of the English alphabet, in April. Most of us choose to make these posts on a particular theme. My theme for 2022 is Codebreaking in World War II, which fits with the topic of the novel that I’m writing. Visit every day (except Sunday) in April for a new post on my topic.
A is for Arlington Hall
Arlington Hall was originally a junior college for young women, west of Washington DC and the Arlington National Cemetery. Near the beginning of World War II, the government took possession of the 100-acre campus and the existing buildings.
Arlington Hall housed the Signals Intelligence Service of the U.S. Army during World War II. This is where army and civilian personnel, mostly women, decoded or decrypted and translated intercepted radio signals.

Arlington Hall worked, mainly, on encrypted Japanese diplomatic and army messages. Bletchley Park, more famously, did similar work breaking European cipher systems, like Enigma. Another women’s college in DC, Mount Vernon Seminary and College, was commandeered by the Navy and became the Naval Communications Annex, performing similar work on the enemies’ naval codes.
Hastily constructed buildings were added to the Arlington Hall campus to house tabulating machines, desks for thousands of employees, and services for those employees (including a beauty parlor, a barbershop, a tailor, and a mess hall).

At Arlington Hall, American personnel learned the secrets of their enemies, everything from the exact itinerary of Admiral Yamamoto’s final journey to the placements of German defenses along the west European coast.
For more information on the women code-breakers at Arlington Hall and the Naval Communications Annex, I recommend the book Code Girls by Liza Mundy. The Achievements of the Signal Security Agency in World War II is a government report written in 1946. It was Top Secret when it was published but now is available on the internet for anyone who wants to learn in great detail about the work done at Arlington Hall.
I’ve always been interested in history of most categories. My father was in World War II over in the Pacific theater. I learned more about this particular history after he started trying to find old comrades. I’d had to look of officers and a few of the names he could recall as well as his unit. What a trip through the Past. I read with different eyes after learning more about my father’s participation.
G’day Joy,
I didn’t realise the US had similar groups of decoders like those at Bletchley Park. I doubt we had anyone doing that job here in Australia. It is great to read about how women in particular played a role in war.
Thanks for sharing an interesting bit of history I was unaware of.
Off to a great start 🙂 I’m already learning new things. You have such a great theme!
Happy A to Z!

Very interesting topic! I’m visiting from April A to Z Roadtrip!
I wonder what kind of security vetting system was in place at that time. Security clearances are a pretty big deal (and long have been) for government employees and contractors; no doubt the code workers were subjected to some level of scrutiny — it makes me curious how that worked.
I wrote a little about that in S is for Secrecy Oath
Stopping by from the A to Z Road Trip. I enjoyed your series this April!
Hello, Joy, I’m finally out and about on the 2022 A to Z Road Trip to visit blogs. 2022 was my first A2Z challenge, and I didn’t get around to all the blogs during April. WWII code breakers is fascinating and intriguing, particularly the female involvement. I’m off to read your B through Z now. Thanks for these history lessons.
