In the final days of the Third Reich, the Allies sent TICOM intelligence assault teams into Germany in search of the signal intelligence secrets of the Wehrmacht. Chief among their targets was the Wehrmacht cryptologic service OKW/ Chi . As OKW/ Chi dissolved in the final days of the war, its archive disappeared, resulting in a months-long search from the northern most border of Germany to the mountains of Bavaria and Austria. This is the story of that search, of which details had remained classified for over 60 years1. 1Many of the TICOM reports cited in this article can be found on the author's website, the TICOM Archive , available at https://sites.google.com/site/ticomarchive/.
