This time 383 bombers participated. While 4,317 bombs fell on the city, the sea and in the surrounding area, only 100 bombs fell within the city. The warning was sounded at 20:12 and the bombers approached again in two waves: 20:12–23:10 on 16 February and 23:45–05:49 on 17 February. The first wave tried to concentrate the bombing by approaching from different directions. In the second wave, the aircraft came in smaller groups from the east. Finnish intelligence had intercepted messages one hour and 40 minutes before the raid and warned the air defense, which had time to prepare. The air defense sounded the warning 49 minutes before the raid. Radar picked up the first aircraft 34 minutes before the beginning of the bombings.
