Hi Ron. Sorry it has been a while since i was last in touch with you. Just looking at the article about the HENRY W. GRADY. Have a look at the voyage records on convoyweb for the D-Day period, it seems that she was in convoy between the 5th till the 7th June. I leave you to draw your own conclusions.
Ron,send me an email,as i might have some information i can send you.
