Dear Mr. Blandin,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the World War II Operations Reports, 1940-1948 in the Records of the Adjutant General's Office, 1917 - 1985 (Record Group 407) that includes records of the 77th Infantry Division and the 132nd Engineer Combat Battalion during WWII. We also located a series titled Unit Histories, 1943 - 1967 in the Records of U.S. Army Operational, Tactical, and Support Organizations (World War II and Thereafter) ( Record Group 338) that includes 15 file units of the 77th Infantry Division during the 1940s. For more information about these non-digitized records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org. We were unable to locate specific records of Company A. Records of lower echelon units sometimes were incorporated into the files of the battalion.
Photographs of various U.S. Army activities dating from 1940 to 2007 are in the custody of the National Archives at College Park - Still Picture (RDSS). Please contact RDSS via email at email@example.com.

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 RDSS. We apologize for this inconvenience and appreciate your understanding and patience.
The U.S. Army Heritage & Education Center, 950 Soldiers Drive, Carlisle, PA 17013, has a large collection of published unit histories. Plus, the U.S. Army Engineer Museum has many unit histories and other materials relating to engineer units in their custody.
Lastly, we searched online and locate the following oral history recording: https://www.witnesstowar.org/combat_stories/WWII/1626
