Military Evacuation Hospital

[MotherMave]

I don't know if this is the right forum to ask this, but I wonder if anyone can locate for me the Military Evacuation Hospital at HOE52B, Postal Sector 79C1059 please. I know is was in or near Chemin des Dames and /or Beaurieux and Aisne. I am researching a British Nurse who was with the French and who was stationed there and suffered bombings on the 27 - 28 May 1918 before being taken prisoner and after a few weeks was sent to Germany. She was held for 4 and a half months. She died in 1920 from Breast Cancer and Exhaustion at the age of 31, bless her. She was awarded the Croix de Guerre and was mentioned in despatches on the 8th September 1918 I am researching this gallant Lady and would appreciate any help with this. Thank you in advance. Mavis
