Doris Brittingham at Normandy

I am researching Doris Brittingham, a nurse from Delmar in WW2, who landed at Normandy Beach.  The question is if she landed on D day or later?  Whichever  day she landed it was not a walk on the beach.  In the Book "And If I Perish" by   Evelyn Monahan, Rosemary Neidel-Greenlee  she is mentioned and a description of her and her fellow nurses landing on Normandy is included.  Here is part of that book
