Thank you Mr Frost for this helpful information. I doubt very much that my Father was on the Elmcrest went she was sunk. However he said very little about the war.
My Mother met him when the Dartford docked in Cardiff and had to go virtually straight back to Sunderland - I remember vividly that she had hysterics on the train! I was 5. I never saw her cry again despite all the losses including that of her Father a month later.
