My father, Simon Mostofsky, was killed in action shortly after D-Day. He was a pharmacist mate caring for the wounded on an LST on its way back to Britain. I never knew the name (actually it’s a number) of the ship he was on, but for some reason I did know it had not been sunk.
In 2010, Ancestry.com sent me a hint for a record that led me to the National Personnel Record Center, Military Personnel Records in St. Louis. http://www.archives.gov/st-louis/military-personnel/ They directed me to the Library of Congress, and I was sent the records identifying the ship as LST 280. When I received the information I did an online search for the LST 280, and found a blog with two email addresses. One responded, amazingly by a gentleman, H. R. Shawhan, who was not only a shipmate, but knew my father well, credited my father with having saved his life during a serious illness, and actually spoke to him just minutes before the fatal torpedo hit.
I was less than a year old when this happened, but receiving this information was very emotional. I did try to arrange a visit with him, but could never get a date. I believe the incident itself was too emotional for him to handle. I am attaching the letter he sent me which is attached to my father’s profile on Ancestry.com.
