FT. MEADE, Md. – Trying to evade the prying eyes of the allied postal censors of WWII, U.S. servicemen and women created secret messages, referred to as Sweetheart codes, to convey their most intimate feelings to one another.

Determined to express their innermost personal thoughts – sometimes in the most passionate of terms – these war-torn lovers employed previously agreed-upon cipher systems to help keep their most romantic thoughts hidden from the government censors.

The National Cryptologic Museum is pleased to offer this Valentine’s Day salute – Sweetheart Codes – featuring historic coded love letters from WWII. The program will run from February 7 through March 31, 2023. Come visit us to get an inside glimpse of the greatest generation’s encoded letters of love.
