Mitchell Zuckoff resurrects a little-known episode in American military history in his new Lost in Shangri-la: A True Story of Survival, Adventure and the Most Incredible Rescue Mission of World War II, which describes an attempt by the Army to extract the stranded survivors of a plane crash in New Guinea. My review of the book ran this week in the Minneapolis Star-Tribune. These lines from Lost in Shangri-la don’t appear in the review but suggest the lively details gathered by Zuckoff: “In New Guinea as elsewhere, Margaret Hastings and other WACs filled strictly noncombat roles, as expressed by their slogan, ‘Free a Man to Fight.’ An earlier motto, ‘Release a Man for Combat,’ was scratched because it fed suspicions among the WACs’ detractors that their secret purpose was to provide sexual release for soldiers in the field.”
