By the oddest coincidence I was just going through my file on John E. Butts. Butts was a native of Medina, New York and was a member of the 108th Infantry, New York National Guard, when it was called into Federal service in 1940. Just before the regiment was transferred from the 27th to the 40th Infantry Division (and soon afterward left for the Pacific Theater), Butts was selected for officer training (OCS) and sent to Fort Bragg, North Carolina.
Upon completion of OCS, Butts was assigned to Company E, 60th Infantry as a platoon leader and served with distinction until killed in action near Flottemanville Hague, France, 23 June 1944. Butts was one of only four members of the regiment - and the only man of Company E - to be awarded the Congressional Medal of Honor for gallantry during World War II.
The above has little-to-nothing to do with your inquiry but I thought you might find it interesting - if only mildly.
As you've pointed out, 60th Infantry was an organic element of 9th Infantry Division. Company E was a component of regiment's 2d Battalion - one of the battalion's three rifle companies. Company E participated in almost every campaign fought in North Africa and Western Europe. They landed in French Morrocco in November 1942 and fought in Tunisia and Sicily prior to being ordered to England to train for the Invasion of Northern France. The company landed with its regiment at Normandy four days after D-Day and fought from France to Germany, via Belgium. You should be able to find any number of excellent accounts of the division's and/or regiment's service as your local public library.
