Thursday August 15
Cloudy in the morning clearing to give fine and sunny weather in the south-east, but remaining overcast in the west and north.
This was the day on which the Luftwaffe launched an all out assault on Fighter Command. It would become known as the Luftwaffe’s ‘Black Thursday’. Events today were many and complicated and hundreds of pages have been devoted to the various actions. To start, I have attempted to establish a simplified timeline of the day’s major events.
1) 11.30-12.00 An estimated 60 Ju 87s with a large force of 50 escorting Bf 109s crossed the coast near Dungeness. They had been seen by RDF forming up over Cap Gris Nez and Nos, 54, 56, 501 and 614 Squadrons sent off to their patrol lines. Only 56 squadron failed to make contact. 26 Ju 87s of II./StG1 bombed Lympne and withdrew without being intercepted. About 30 Ju 87s of IV(St)/LG1 made for Dover and Hawkinge, both being bombed. No. 501 Squadron managed to bounce these Ju 87s. A small group of Bf 110s flashed over Manston strafing and bombing as they went. No 54 Squadron attacked a large group of Bf 109s off the coast of Dover, and then found Ju 87s bombing the port, protected by at least 40 Bf 109s orbiting above. As 615 Squadron arrived its B Flight was bounced by these Bf 109s.
Luftflotte 5 based in Norway and Denmark launch simultaneous attacks on the north east coast.
2) 12.30-13-15 A diversionary raid by He 115 floatplanes attempted to lure fighters north in the belief that Edinburgh was the target. Radar showed a large plot approaching the Northumberland coast and Nos. 72, 605, 41, 79 and 607 Squadrons were scrambled. 72 Squadron, searching for a 30+ raid was the first to see the German air armada, about 30 miles off the Farne Islands. They met a large force of He 111s with an escort of Bf 110s. This was 63 He 111s of I and III./KG 26 with an escort of 21 Bf 110s of I./ZG 76. Legend has it that F/Lt Graham hesitated on seeing this formation, leading one of his pilots to enquire whether he had seen the enemy formation. Graham who had a stammer, supposedly replied ‘Of course I’ve seen the b-b-b-bastards, I’m trying to w-w-w-work out what to do’. Graham and 72 squadron attacked and managed to separate some of the escorts from the bombers. Off Sunderland the formation split into two formations one heading NW the other SW. No 79 Squadron was next to engage, attacking come Bf 110s approaching Acklington and then a large formation He 111s, escorted by more Bf 110s, headed towards Newcastle. No. 605 Squadron also attacked this formation, its B Flight attempted to stand between the bombers and Newcastle. No. 41 Squadron attacked the southern formation, joined by No. 607 Squadron a few minutes later.
3) 12.10-14-00 A second raid was plotted 100 miles to the south, estimated 30+, heading for Scarborough. This raid consisted entirely of the 50 Ju 88s of I, II and III KG 30, flying from Aalborg in Denmark. This raid crossed the coast near Bridlington and also split into two formations, one headed south for Driffield, the other north towards Tyneside. Nos. 616, 264 (Defiants), A and B Flights of 73 and 219 Squadron (Blenheims) were all ordered off. No 616 Squadron sighted the raid ten miles of Flamborough Head and were joined by B Flight of 73 Squadron in an interception. A Flight failed to make contact, as did the Defiants of 264 Squadron. The Blenheims of 219 Squadron made contact, but were far too slow to make meaningful attacks, they engaged in fruitless tail chases with the retreating Ju 88s. Driffield was heavily bombed, 14 service personnel were killed, including Margueritte Hudson, a 19 year old WAAF, the first to be killed in the Battle of Britain.
A large raid developed over Kent, which may have been intended partly as cover for a precision attack by Eprg 210.
4) 14.50-15-15 Back in the South East, and five raids, an estimated 250 aircraft, Do 17s with escorts of Bf 109s appear on 11 Groups plotting table. Nos. 64, 151, 111 and 501 Squadrons were scrambled to their patrol lines. No. 64 Squadron engaged Bf 109s at 22,000 feet, but were in turn attacked by another formation of 30 Bf 109s. No. 151 Squadrons Hurricanes were ordered to attack bombers over Deal, but were driven off by the escorting Bf 109s. No 111 Squadron had more success, attacking the Do 17s of I and II./KG 3 chasing them out over the Thames estuary. III./KG 3 meanwhile went to Eastchurch, again. Just 7 Hurricanes of No 501 Squadron reached their patrol area in time, to find an estimated 150 Do 17s high above them crossing the coast near Folkestone. They climbed to engage and chased the bombers across Kent to the Thames estuary. Other smaller raids by KG I and II attacked targets in Kent and were not intercepted. Their notable successes were the bombing of the Short’s and Pobjoy works in Rochester, disrupting production at both for several days.
5) 14.55-15-30 A large raid passed North Foreland undetected because the RDF station was still off air. This was an attack by Epgr 210 on Martlesham Heath in Suffolk. The raid was not plotted until it was just off Orfordness and though elements of no less than eight squadrons, some of which were already airborne, were tasked to the raid only 1 and part of 17 squadron intercepted. 32 squadron sighted some raiders but failed to intercept. None of the others made contact. This is surely a sign of what might have been. Martlesham Heath was not badly damaged, though two hangars were hit.
6) 17.30-17.45 10 Group began to see a large raid developing. By 17.20 seven raids were detected approaching the coast between Portland and Selsey Bill. Nos 10 and 11 Groups would despatch the largest fighter force yet assembled. In defence of Portland Nos. 152, 87 and 213 Squadrons are sent off. 152 was first to see the enemy, 47 Ju 87s of I./StG 1 (target Warmwell) and II./StG 2 (Yeovil) escorted by 40 Bf 110s and 60 Bf 109s. The other two squadrons also arrived to intercept.
7) 17.30-19.00 First Phase. Between Thorney Island and Winchester. Two relatively small raids of 30 Ju 88s with 20 Bf 110 escorts crossed the coast at Selsey Bill, heading for the airfields at Andover and Worthy Down. Between 17.05 and 17.50 Fighter Command despatched twelve squadrons. Nos. 43, 111, 32 and 601 engaged this raid.
Phase Two. Middle Wallop to Southampton. No 609 Squadron took off as Middle Wallop was bombed, the raid was engaged by 249 squadron as it withdrew. No 234 Squadron, patrolling near Swanage caught sight of the raid as it withdrew and also made an attack.
For a second time today a large raid over Kent served as a diversion for a smaller precision raid.
8) As the earlier raids withdrew a series of new RDF plots appeared, 60+ aircraft approaching the coast between Dover and Dungeness. This raid again divided, Ju 88s and Do 17s heading for Biggin Hill, but bombing West Malling and a smaller raid of the Bf 110s of Eprg 210 heading for Kenley, that bombed Croydon. One airfield looks much like another. Fighter Command sent off Nos. 266, 54, 610, 615, 501, 151, 64 and 43 Squadrons. The ‘West Malling’ raid was met first by 266 squadron off Dover and several others engaged. West Malling was bombed and rendered inoperable for four days. The ‘Kenley’ raid was intercepted by Nos 32 and 111 Squadrons and Eprg 210 was badly mauled losing seven of its Bf 110s, including that of Hptm Walter Rubensdorffer, the Gruppenkommandeur, who was killed.
What were the results of the day’s action?
First, the British view. The Ju 87s bombing Kent in the first raid had caught no aircraft on the ground, but hangars and other facilities at both Hawkinge and Lympne were destroyed and damaged. Dover, Rye and Foreness radar stations were put off air for the rest of the day, but the Luftwaffe ignored such success and anyway never sought to exploit it.
32 civilians were killed and 105 injured in the ‘Battle of Sunderland’ as He 111s scattered their bombs over a large area.
The Ju 88s that bombed Yorkshire killed three men and caused substantial damage and casualties at Driffield, also destroying nine Whitley bombers and a Miles Magister trainer.
The bombing of Rochester caused damage to the airfield and disrupted production at the Short Bros. and Pobjoy works.
Eastchurch was bombed again, but little damage done.
Eprg 210’s raid on Martlesham Heath caused widespread damage and destroyed one Fairey Battle.
The Ju 88s that managed to bomb Andover (an Army Cooperation Command airfield) and Worthy Down (Fleet Air Arm) did little damage, but Middle Wallop was hit again.
The attack on West Malling (intended for Biggin Hill) killed two airmen. The field was not operational anyway. Eprg 210’s attack on Croydon (intended for Kenley) did considerable damage and killed 6 airmen and 62 civilians, but at great cost to the attacking unit.
As for the fighting in the air, the RAF had lost 25 fighters (11 Spitfires, 14 Hurricanes) with another 19 damaged. 12 pilots had been killed and another 3 lost as PoWs.
So what of the Luftwaffe?
Aircraft that failed to return amounted to 25 Bf 110s, 16 Ju 88s, 9 He 111s, 6 Ju 87s, 6 Bf 109s, 3 Do 17s, 1 He 115, 1 He 59 and 1 Ar 196, total losses of 68 aircraft. Another 20 aircraft returned damaged, some written off. 184 airmen were killed or taken prisoner.
The Luftwaffe pilots claimed to have shot down 102 British fighters. This was reduced by Luftwaffe Intelligence by about 30%, to 70. It was another manifest failure of the Luftwaffe Intelligence service. Kesselring chose to believe the figures, reckoning the Fighter Command must already be on its last legs. Hugo Sperrle, commanding Luftflotte 3, did not and concluded that Fighter Command might still have 1,000 aircraft at its disposal. Neither was correct, but Sperrle was closest.
