Once again, the main activity on the part of the enemy reconnaissance flights along with attacks by Me109s flying solo and small numbers of Ju88s. The weather held back the RAF in their pursuit of these marauders. In the early evening, Hornchurch was attacked by a single plane. That day there had also been bombs on Harrogate and Hastings.
That day a large delayed action bomb fell next door to the north wall of St. Paul’s Cathedral in London which took several days to extract. The bomb disposal experts who extracted the bomb were awarded the George Cross. The RAF flew 247 sorties but lost no planes while the Germans suffered 4 aircraft destroyed.
That night Liverpool, London and Blackpool were bombed. Bomber Command carried out further attacks on the German barges.
