Dear Mr. Lawless,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and found European Theater of Operations United States Army (ETOUSA) Operational Maps, Engineer Division Letters and Operations Reports, Appendices A-Q to Communications Zone Plan and Background Files to the Study "The Lorraine Campaign".
We also suggest that you contact the National Archives at College Park - Cartographic (RDSC) via email at email@example.com for any information pertaining to digital map data they may have in their custody.
We hope this is helpful. Best of luck with your research!
