Looking for World War 2 146th combat Engineesrs company A. how to find members of or records for?

Question

World war 2. My grandfather EDUARDO S. VILLIARREAL from Texas served from DDay in Normandy and other European campaigns. He was in Co. A of the Army 146th Combat Engineers.
I think it was part of IV or ivy, company as well.
In his letters, he mentions a SAM H BALL FROM TEXARKANNA TEXAS
& LT. KAHALY.
He rode home on the SS TEXARKANNA VICTORY, & was on it for Thanksgiving, 1945.
He rarely spoke of the war, and I am looking for ANYONE with any info, pictures, ANYTHING that can help me piece this together .
Thank You

Answer 1

There's a unit website with reunion information and an official history. For additional information you could try contacting the Army Engineer Association at their website.

There's an excerpt from a letter or memoir by"Wild Bill" Kehaly on the battalion website, btw. Maybe the same Lt Kahaly? He mentions Captain Sam Ball.
