After 1939 she covered several key military confrontations in Western Europe, including Monte Cassino and the Battle of the Bulge. In June 1944, she stowed away on a hospital ship to report on the D-Day landings and entered Dachau with American troops in May 1945. In 1966 she covered the war in Vietnam with a series of six dispatches for The Guardian. The authorities later refused her accreditation to work in South Vietnam. In the 1980s she travelled in Central America, writing about the wars in El Salvador and Nicaragua. A few years later she published a report from Panama in the wake of the US invasion. Her last long piece of reportage, written shortly before she died, was about street children in Brazil. She was the author of several novels and collections of short stories. Her war reportage can be read in The Face of War. The View from the Ground, a collection of her other journalism, was published in 1988.
