We have what we call our "bible" - THE CORPS OF ENGINEERS: THE WAR AGAINST GERMANY, which has a lot of mentions of the 291st plus maps, see: https://archive.org/details/corpsofengineers00beck which you can read online. Go to the index for 291st to find relevant pages.
Thank you for the book !
Hi and welcome. Your English is fine!
Unfortunately, you can only obtain discharge information if you are a direct descendant of the family. You have to be a son or daughter, granddaughter, etc.
We can try and find a family member here in the states. Sometimes it does work and we get lucky.
Let me see what I can discover.
All the best!
Thank you very much for your help ! I'm looking forward to hearing from you ! If there is anything more I can do, please let me know.
