Dear Ms. Ferrell,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located 10 series in the Records of the U.S. Forces in Southeast Asia (Record Group 472) that pertain to deserters during the Vietnam War.
We also located a series titled Serious Incident Reports, 1968 - 1973 also in Record Group 472 that may include information about their escape. Please review these series and then contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org for more information.
If they were tried, U.S. Army general courts-martial (GCM) records from 1917 to 1976 are in the custody of the National Archives at St. Louis (RL-SL). For access to the records, please contact RL-SL via email at email@example.com.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RTD2 and RL-SL. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is useful. Best of luck with your research!
