In June KG 55 continued long-range operations. It is believed the "Geschwader" flew to Marseille on 1 June 1940 on a leaflet-dropping exercise with "Kampfgeschwader" 53. On 3 June the entire wing flew on Operation Paula—a mass attack against industrial targets around Paris. It supported the drive of the Army Group B to Paris until the city's capture on 14 June. The last operations were flown on 22 June 1940, three days before the French surrender. From 6–19 June the formation operated in "Geschwader"-strength against troop concentrations and rail targets around Nancy. Between 20 and 23 June 1940, KG 55 were already operating over the United Kingdom, bombing targets in Bristol and Cardiff flying from forward airfields near Paris.
