 After D-Day, the USAAF Black Widows moved to Advanced Landing Grounds at Maupertus (A-15) (422d NFS) near Cherbourg and Vannes (A-33N) (425th NFS) in Brittany France to intercept German night fighters and bombers attacking Allied positions.Although several interceptions of night-flying German aircraft were made, most Black Widow missions were night intruder missions against trains, armor, and other ground targets.The 422d eventually served at A-39 (Chateaudun) in France, then at A-78 (Florennes/Juzaine) in Belgium, then Y-59 (Strassfield) and R-2 (Langensalza) Germany.
