My father never talked much about Puerto Rico either, and thus I am curious as to what the mission(s) were going on there at that time. When he was stationed in Atlanta before going to Puerto Rico in 1945, he worked for the War Department as an attorney, investigating dependent claims and prosecuting/defending various soldier crimes, such as AWOL. But, I don't know if that's what he did in Puerto Rico. He did not say. I contacted the head person of JAG at one time, and he did not have information. Letters from my father to mother at that time were censored for content, so they do not provide much information. I saw your post, and thought that I would ask. I believe there is a story there of some sort, but I don't know what. I do remember my father saying he got to fly in the Colonel's airplane--and he found that much superior to typical military airplanes. Thank you.
