My wife had a distant relative who served in the 1339th Engineer Construction Battalion during WWII. He served between 1942 and 1946, returning home multiple times, based on a military bonus application I found on Ancestry.com. I would love to add more detail in the family tree on his time in the service but am unable to find any documents or resources detailing that particular battalion. Any help would be appreciated!
Here is an image of the bonus file:
