Camels and Doughboys by Darby Perrin

185th Sopwith Camels depart in the waning light of day. Known as the "Bats", the 185th Aero Squadron is notable as it was the first and only night pursuit (fighter) squadron organized by the United States during World War I. Its mission was night interception of enemy aircraft, primarily bombers and observation aircraft. It was engaged in combat for less than a month before the end of hostilities in 1918.
