Traffic between the USNCML and Op-20-G4

Messages sent between the USNCML in Dayton and the Naval Communications Annex at Nebraska Avenue, Washington

The text of messages, and the listing of messages sent between Dayton and Washington were a useful way to describe the struggle to get bombes up and running in the documentary Dayton Codebreakers. They form a dramatic narrative of the successes and failures of the NCR and Navy crew in 1942 and 1943. I'm including some key pages here, along with the personnel roster and glossary at the beginning of the listing.
