The first mission on 25 October, a night attack of 16 aircraft on Harwich led to three bombers being lost, with one crashing on takeoff and two becoming lost on their return. On 11 November a formation of 10 BR.20s escorted by Fiat CR.42 biplane fighters on a daylight raid on Harwich, was intercepted by RAF Hurricanes. Three bombers were downed and three CR.42s destroyed with four damaged, with no loss to the Hurricanes. In early January 1941 all of the bombers were redeployed.
