Essential background information

  • Documents specific to the American Bombe posted by Frode Weierud
  • Information about the Battle of the Atlantic posted by the Mariner’s Museum of Newport News, Virginia
  • This week I received a tip to look at “Important People of WWII” at the True People Search site. The selection of people listed is interesting and helpful background; a listing of sources might have given folks places to read more about them. There’s always wikipedia. Thanks to Chris, and teacher Jane Ziegler.
