80 Years Ago—December 25, 1939: For Christmas in Britain, midnight church services are cancelled so stained glass windows won’t have to be blacked out, carolers are not allowed to use handbells, and the carol service at Westminster Abbey is cancelled since the choirboys have been evacuated from London.
Soviets attempt to break out at Suomussalmi, Finland, but fail.
