London: The Reuters News Agency reported:
The southeast of England has been the arena of heavy dogfights. This morning more than 300 German aircraft took part in the raids; but the RAF fighters foiled the intrusion of the enemy planes. Dozens of Messerschmitt fighter planes dived from a great altitude to protect their bombers, but the British air defence was so effective that in most cases the enemy wings had to veer off and change course.
