Send a message to the person who requested a photo of the grave monument of Derek Boileau Lang with the following comment:
I'm researching WW2 recipients of the Military Cross and Derek Lang was awarded his for a particularly audacious escape from captivity following the fall of France in 1940. This will link in with his Telegraph Obituary published in 2001. Thank you for your time and for being in a position to supply a copy of this memorial.
