German intelligence reports 71 aircraft destroyed - including all of 65 Sqn on the ground at Manston. (Actual RAF losses were 22 from 732 sorties.)
Luftwaffe signals chief Martini assesses that all radar stations are still operational. (Ventnor appeared on line as it is transmitting powered by a backup generator but it is unable to receive any echoes so is actually not functioning.) Conclusion is that operations rooms must be well protected underground and it is only possible to shut down radar coverage for short periods.
Reichsmarscahll Göring gives the order to launch Adler Tag the following day - this is intercepted by the British Ultra.
