Sorry I previously said it was her son.
From a facebook message this afternoon:

my boy is home.
i remember, every halloween, he’d dress up as a soldier, it’s all he’s ever wanted to be.
before he left, he and his granddad looked at dad’s album from ww2.
it was like watching the passing of the guard onto the following generation.
but, now my boy is home.
i am overjoyed.
