On this Memorial Day, I am re-upping this post (with edits) that I first wrote 10 years ago.
I always knew him simply as Cousin Del, even though he was actually my mom’s cousin, not mine. He never married and took care of his mother until her death. After my family moved to Minnesota (in the 1970’s) he would turn up at various family functions. He was a pleasant (but quiet) man, with a witty sense of humor.
After his mother died, he stopped coming to family events and became a bit of a recluse. At first he would take phone calls from his cousins, but in recent years had even stopped doing that. Dropping by his home to say hi was definitely not appreciated. The cousins would occasionally drive by his house to see if the lights were on and the lawn mowed, 2 things that would indicate he was OK.
He died in 2013.
In the last visit my mom, her sister, and a cousin had with him he told them (for the first time ever) that he had been captain of a landing craft on D-Day. All day long he transported soldiers from the ships to the beaches, back and forth, knowing that many of them were disembarking to their deaths, and knowing that he could be shot as well. This would have been his view.

The recluse cousin, it turns out, was a hero.
Thank you, Cousin Del.
