III./KG 2 did not. KG 2 had formed up by 05:10, led by Geschwaderkommodore Johannes Fink. Part of the ZG 26 formation that had taken off—led by Oberstleutnant Joachim Huth—tried to warn the Dorniers of the cancellation. Unable to contact the bombers by radio, Huth tried to signal them by flying in front of them and performing aerobatics. Fink ignored him and flew on. KG 2 flew around the coast to his target, Eastchurch airfield on the Isle of Sheppey. Albert Kesselring had issued orders for bombers to abandon missions if their escorts did not show up, but Fink did not want to be accused of failing to obey orders and continued onward even though the Bf 110s turned back. The return leg would take KG 2 across No. 11 Group's territory, which could have been disastrous without fighter escort. But owing to the Observer Corps misjudging the direction of the bombers, due to low-lying cloud, and the radar not picking up the direction of the German bombers, the WAAF plotted the course of the raid incorrectly and the RAF failed to prevent the target being attacked. For an hour after dawn on 13 August, there were few German tracks upon the plot tables in operations rooms, and none at all in the central and eastern Channel. The first signs of concentration, however, came earlier than usual, for between 05:30 and 05:40 two formations of 30 or more aircraft were located in the Amiens area. For 30 minutes, they remained over land, but at 06:10 they began moving inland. The Observer Corps and radar tracked them and guided the RAF units to intercept. Unaware of the German intent, the controllers directed three full Squadrons and detachments of three others were alerted by 06:15. No. 151 was protecting a convoy in the Thames, No. 111 was protecting RAF Hawkinge and No. 74 Squadron RAF was covering RAF Manston. Parts of No. 85, No. 43 and No. 238 Squadron RAF were also airborne near London. By 06:25, the German formations were well over the Channel. No. 238 was moved to cover their own base at RAF Warmwell. No. 257 Squadron RAF was also ordered to take off at 06:20 to patrol Canterbury. Not satisfied with the strength of the forces already airborne, controllers dispatched No. 601, 213, 64 and 87 Squadrons to intercept between 06:30 and 06:35. The first combats began at
