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.
