Original Title: TIL In January 1944 the Australian 9th Division found the Japanese 20th Division’s entire cryptographic library in New Guinea. The codes were buried in a steel trunk during a retreat and found by engineers looking for mines. This find lead to around 36,000 messages being decrypted in March alone.
