On June 25, 1950, North Korean troops crossed the 38th parallel into South Korea to start a war of unification they thought would last three weeks. Three years later, with 33,000 American troops dead and 105,000 wounded, the war ended with the North and South divided exactly as they were before it began. The Coldest Winter: America and the Korean War, sadly David Halberstam's last book, is a powerful chronicle of "the century's nastiest little war," a bitter conflict, fought on harsh terrain in ghastly weather. This is detailed, documented history, military and political, animated by Halberstam's unique energy, authority and narrative flair. The voices of the men in the trenches add affecting, often nightmarish, images of that "sour," unwanted war.
