Here is some information for you. https://www.findagrave.com/memorial/84683120/john-c-hamilton
531st Engineer Shore Regiment, Company C. I've been told that some men had training in Ft. Belviour, VA. The 531st in England I think near Plymouth. The 531st ESR, had returned to England were they had been at Anzio, Italy. Then soon began training for the Normandy attack. The 531st was at Utah beach in Normandy. From what I know is the 531st ESR, in St Mere Eglise, St Lo, Carantan, Cherebourg, in France. Maastricht and Auchen in Holland, Belgium, and Germany. I also know that shortly after D-day sometime in 1944 the 531st was re-organized to the 3053rd Engineer Combat Battalion.
Sir - Thank you for your efforts. John S. Hamilton, Chicago, IL died in 1996 (car accident). He was involved in building Bailey bridge across Albert Canal and trying to demo a bridge in Maastricht Dec 1944. However, your information has been most helpful!
Dear Mr. Moeller,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located Organizational Unit Records, 1943 - 1947 in the Records of Headquarters, European Theater of Operations, United States Army (World War II) (Record Group 498) that includes 3 file units titled 531st Engineer Shore Regiment 1944; 3053rd Engineer Combat Battalion (Amphibious) 1945; and 3053rd Engineer Combat Battalion (Amphibious) November 1944-August 1945. The records are not digitized. We also located the World War II Operations Reports, 1940-1948 in the Records of the Adjutant General's Office, 1917-1985 (Record Group 407) that may include records of the 531st and 3053rd Engineers during WWII.

We suggest that you request a copy of his Official Military Personnel File (OMPF). OMPFs and individual medical reports for officers of the U.S. Army who were separated from the service after June 1917 and before 1959 are in the custody of NARA's National Personnel Records Center in St. Louis. In many cases where personnel records were destroyed in the 1973 fire, proof of service can be provided from other records such as morning reports, payrolls, and military orders, and a certificate of military service will be issued. Please complete a GSA Standard Form 180 and mail it to NARA's National Personnel Records Center, (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. For more information see Official Military Personnel Files (OMPF), Archival Records Requests.
Selective Service records for individuals who served after World War I and were born before 1960 are in the custody of the National Archives at St. Louis (RL-SL). There are two types of records: cards and classification histories. The individual Draft Registration Card (SSS Form 1) may contain information such as: name, Selective Service registration number, age, date and place of birth, ethnicity, place of residence at time of registration and basic physical description. The Classification History (SSS Form 102) may contain: name; date of birth; classification and date of mailing notice; date of appeal to the board; date and results of armed forces physical examination; entry into active duty or civilian work in lieu of induction (may include date, branch of service entered and mode of entry, such as enlisted or ordered); date of separation from active duty or civilian work; and general remarks. Please complete a Form NA-13172 to request a search of these records and email it to RL-SL 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 RDT2 and RL-SL. Also, the NPRC is closed except for emergencies. Currently, NPRC will continue servicing requests ONLY associated with medical treatments, burials, and homeless veterans seeking admittance to a homeless shelter. If your request is urgent, please see Emergency Requests and Deadlines. Please refrain from submitting non-emergency requests such as replacement medals, administrative corrections, or records research until NPRC returns to pre-COVID staffing levels. Please check archives.gov/veterans for updates to the NPRC operating hours and status. We apologize for any inconvenience.
We hope this is helpful. Best of luck with your research!
