Dear Mr. Cizewski,
Thank you for posting your request on History Hub!
We searched the World War II Operations Reports, 1940-1948 in the Records of the Adjutant General's Office (Record Group 407) and located after action reports and supporting documents for 23-30 April 1945 & 1-10 May 1945 of the 27th Tank Battalion, 20th Armored Division. The 27th was temporarily attached to the 42nd Infantry Division from 24 April to 10 May 1945. For access to and/or copies of these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at email@example.com.
We hope this information is helpful. Best of luck with your research!
