From there, the menu would be passed to Jimmie Lee or another bombe deck operator. If there was a hit, it would go to somebody like Margaret Gilman, from Bryn Mawr, who would run it through the M-9 to see if the “hit” produced coherent German. Once they got a key setting, subsequent messages for that day could be run through the M-9 and translated, without having to use the bombes. Soon, the operation was so smooth that most keys were obtained in hours and most messages decrypted immediately.
