Chosin Breakout This blown bridge at Funchilin Pass blocked the only way out for U.S. and British forces withdrawing from the Chosin Reservoir in North Korea during the Korean War. Air Force C-119 Flying Boxcars dropped portable bridge sections to span the chasm in December 1950, allowing men and equipment to reach safety.
