On the night of the 5th, 140 aircraft dropped 203 tons of H.E. bombs and 7,200 incendiaries on the dock area at Brest, and, on four other nights, a total of 126 aircraft dropped a further 186 tons of H.E. bombs and 12,680 incendiaries on the same objective. Visibility was generally poor, but, during the heaviest raid, occasional gaps in the cloud enabled the crews to observe bomb bursts in the dock and dry-dock areas and along the torpedo boat quay. They also saw large fires followed by explosions in the town and Port Militaire.
