Seeking information about the 528th Field Artillery Battalion

I'm researching my grandfather's WWII military service, and I'm trying to find information about the unit he was with.

He was a lineman in the 528th Field artillery battalion, Hq & Hq battery.  He arrived  in Liverpool Europe with the unit on

November 13 1944 and  left for the USA on Aug 6 1945 on the Pierre Soule troopship, from Le Havre.

Does anyone have any information on this unit or battery that you can share with me?

Thank you,
