On the 22 July 1917 KG 3 attacked once more England and bombed a number of targets. Some claims were made on German Gotha's but no proof was found of that as far as I know...
However the British planes suffered some losses, due to the fact that in London the red alert had been given in mistake and maroon rockets were fired off which made some AA batteries in the southnern Essex area that the bombers were near them, which resulted in opening fire on their own planes of which some British sources said that 2 were shot down by them. However we did not find any proof of that either. Does anyone have any more on this ? They are not in Henshaw.
Thanks and best from Johan
