Red Harvest is a play in three acts by Walter Charles Roberts that uses pages from an American Red Cross nurse's diary detailing her experiences working with the Red Cross in France on the Western Front during World War I as its source material. Set in American Red Cross Hospital 111, a field hospital in Jouy-sur-Morin, the play takes place in 1918 at the time of the Battle of Château-Thierry. The play centers around the head nurse, Zinna Meek, as she struggles to lead the under staffed and under supplied hospital through a dangerous time when the hospital itself is experiencing air raids, shell fire, and a large crowd of severely wounded soldiers, many of whom are difficult surgical cases.
