125th Field Artillery 34th Div (Red Bull)

Trying to find records, roster, pictures ect. One of my uncles served in Headquarters Battery enlisted 11/12/1941 was discharged 7/26/1945
When he left for basic training he served 5 months 18 days in the US then served 3 yrs 2 months 18 days before he returned home. Once he went to basic he didn't return until after the war. Sgt Allen Alexander was in the battles of Tunisian,Foggia,Rome,Arno,Appennines,Fo Valley. Medals he received European African Middle Eastern Theater Ribbon with a Silver Star, Good Conduct Ribbon and the American Defense Service Ribbon. If anyone can steer me in the right direction on getting this info a big thanks
