She works alongside Kathleen an American nurse and Alice a new English nurse. Charlotte is called to help at a Casualty Clearing Station, this is very close to the front line fighting and is one of the first places the wounded arrive at. Working in terrible conditions they treat the men with little or no anaesthetic, sewing up wounds, amputating as necessary, shipping the men through as the centre is hit by debris and gas. Here she first meets Robert Fitzgerald, a gallant soldier who treats her like a Lady.
