Heavy attacks on London, broken up by Fighter Command. Highest German losses since 18 August [185 claimed by the RAF] force a serious rethink by the German High Command.

Night: Heavy damage to London.

Weather: Fair with some cloud patches. Fine during the evening.

By mid-September 1940, the Luftwaffe’s campaign against Fighter Command had reached a critical juncture. Adolf Hitler had set a provisional date of 17 September for Operation Sea Lion, contingent on German air superiority being achieved. With time running out and the autumn weather becoming increasingly unpredictable, Reichsmarschall Hermann Göring issued orders on 14 September for a maximum-effort daylight assault on London the following day. It would be the fifth large-scale attack on the capital and was intended to crush British morale and destroy the last of Fighter Command’s strength. Specific flight paths and bombing altitudes were distributed to bomber Gruppen. While the Germans remained unaware of the limitations of British radar above 20,000 feet, they had begun flying at higher altitudes in the belief that such tactics had delayed RAF interceptions in recent raids.

Despite repeated promises that one final blow would bring victory, morale among German aircrews was low. Luftwaffe crews had been told in July and again in August that Fighter Command was nearly defeated, yet every raid met fierce resistance. As General Adolf Galland later recalled:

“Failure to achieve any notable success, constantly changing orders betraying lack of purpose and obvious misjudgment of the situation by the Command… had a most demoralizing effect on us, the fighter pilots, who were already overtaxed by physical and mental strain.”

In Britain, the picture was different. Fighter Command had recovered much of its operational strength. Airfields had been repaired, aircraft losses replenished, and radar stations were restored to full capacity. The Luftwaffe’s daily bombing of aerodromes had not succeeded in breaking down the system. By 15 September, the RAF was ready.

Enemy Action by Day

Weather over southern England had cleared after overnight rain, with fine conditions prevailing beneath a broken cloud base. At RAF Uxbridge, Air Vice-Marshal Keith Park received early radar reports indicating increased German aerial activity over northern France. That morning, Prime Minister Winston Churchill visited No. 11 Group headquarters. At the time of his arrival, the plotting tables showed little more than scattered reconnaissance tracks, and WAAF personnel continued their duties as normal.

The first daylight combat occurred shortly after 08:00 hours. A Heinkel He 111 from Aufklärungsgruppe 51, engaged in long-range reconnaissance, was intercepted over the Channel by Hurricanes of No. 87 Squadron and shot down. A Heinkel He 59 air-sea rescue aircraft was dispatched to search for survivors but found no trace of the bomber or its five-man crew. Further high-altitude reconnaissance flights by Ju 88s penetrated deep into Britain during the morning, photographing targets ranging from RAF Sealand and Chatham Dockyard to Manchester and Liverpool. These aircraft flew above the effective interception ceiling, and all returned safely.

Though these early movements caused no damage, their scale and pattern suggested that a major operation was imminent.

10:10–13:00 Hours: The Noon Attack

At 10:10 hours, the first major German formation became airborne. Major Alois Lindmayr, Gruppenkommandeur of I./Kampfgeschwader 76, led the attack. A veteran of the French campaign and holder of the Knight’s Cross, Lindmayr commanded a force of Dornier Do 17s drawn from both I. and III./KG 76. III./KG 76 contributed 19 aircraft from Cormeilles-en-Vexin, while I./KG 76—reduced by attrition—could muster only eight serviceable bombers. As a result, two Gruppen were committed to perform the task normally assigned to one.

The formation rendezvoused over Amiens before proceeding toward Cap Gris-Nez to meet its fighter escort. En route, cloud disrupted cohesion, delaying the force by approximately ten minutes while it reformed. Two bombers failed to rejoin and returned to base. Among the attacking aircraft was a Dornier piloted by Feldwebel Rudolf Heitsch, experimentally fitted with a rear-mounted infantry flamethrower intended to deter close pursuit.

At 10:30 hours, Chain Home radar stations—particularly Dover—reported a hostile concentration forming over the Pas-de-Calais. The filter room at Stanmore confirmed the tracks, and group and sector commands were alerted that more than forty aircraft were entering Kentish airspace. By 11:04 hours, Lindmayr’s force had reached Calais. Wing Commander Lord Willoughby de Broke, Park’s senior controller, observed the raid’s progress alongside Park and the Prime Minister, uncertain whether the plots represented bombers or fighter sweeps.

Park elected to gamble. At 11:15 hours, he committed nine squadrons from Biggin Hill, ordering Nos. 72 and 92 Squadrons to patrol at 25,000 feet over Canterbury. No. 603 Squadron was to follow and attack the close escort. Further squadrons were held in readiness at Northolt, Kenley, Debden, Hornchurch, and North Weald.

The bombers crossed the English coast at Folkestone at 11:36 hours. Escorting them were Bf 109s from JG 27 and I./JG 52 at medium altitude, JG 53 providing top cover, and approximately thirty aircraft from JG 3 flying close escort. Elements of Lehrgeschwader 2 operated ahead of the main force. A strong headwind slowed the Dorniers, increasing fuel consumption among the Bf 109s while simultaneously aiding RAF fighters climbing from the north.

By 11:50 hours, Spitfires of Nos. 72 and 92 Squadrons attacked from above, breaking up JG 53’s high cover. No. 603 Squadron soon joined the engagement against JG 3’s close escort, while Hurricanes of Nos. 253 and 501 Squadrons pressed home head-on attacks against the bombers, holding formation under intense defensive fire. Additional RAF squadrons entered the battle as the fighting spread across Kent and south-east England.

During these opening engagements, German fighter losses mounted rapidly. At approximately 12:00 hours, a Bf 109E-4 (W.Nr. 3182) of 1./JG 52 was shot down over Ashford by Pilot Officer G. H. Bennions of No. 41 Squadron and Pilot Officer C. A. McGaw of No. 73 Squadron. The aircraft crashed at Dering Wood, Berry Court, Biddenden Green, after Lt. H. Bertel baled out and was captured.

At 12:07 hours, as the outskirts of London came into view, the Bf 109 escorts began disengaging and turning back towards France as fuel reserves ran low—precisely the effect Park had intended through his policy of continuous interception along the bombers’ route. The Dorniers pressed on and released their bombs over London, striking rail lines near Battersea Park on the south bank of the Thames. Although tracks and a viaduct were damaged, repairs were completed within days.

Bader’s Duxford Wing—Nos. 19, 242, 302, 310, and 611 Squadrons—arrived over London and immediately engaged the German formations as they began their bombing run.

Around the same time, at 12:09 hours, Flying Officer A. D. J. Lovell and Pilot Officer J. D. Smith of No. 73 Squadron destroyed a Bf 109E-4 (W.Nr. 5197) of 1./JG 53 during combat over Canterbury. The fighter crashed at Adisham Court, Bekesbourne, and Fw. H. Tschoppe baled out and was captured, though severely burned.

At 12:15 hours, Pilot Officer R. H. Holland of No. 92 Squadron shot down a Bf 109E-4 (W.Nr. 5205) of JG 3 near Bilsington. The aircraft crashed into outbuildings at Tarpots Farm, and Oberstlt. H. von Wedel was captured.

As the German escorts withdrew, Hurricanes of Nos. 504 and 257 Squadrons intercepted the trailing Dorniers over south London. One bomber, a Do 17Z (W.Nr. 2361, F1+FH) of 1./KG 76 flown by Oblt. R. Zehbe, had fallen behind the formation with engine trouble and came under repeated attack from Flight Lieutenant J. Jefferies, Sergeants J. Hubáček, R. Půda, and J. Kaucký of No. 310 Squadron, Pilot Officers J. Curchin and A. K. Ogilvie of No. 609 Squadron, Flying Officer P. T. Parsons of No. 504 Squadron, and Pilot Officer A. C. Cochrane of No. 257 Squadron.

The bomber was finally destroyed when Sergeant Ray Holmes of No. 504 Squadron collided with it during the engagement. The Dornier disintegrated in the air and crashed onto the forecourt of Victoria Station. Bombs released during its descent fell near Buckingham Palace, causing damage but failing to explode.

Uffz. H. Goschenhofer and Uffz. G. Hübel were killed. Zehbe baled out and landed in Kennington, where he was attacked by civilians; he later died of his wounds. Obgfr. L. Armbruster and Uffz. L. Hammermeister also baled out and were captured. Holmes escaped by parachute, injured but alive.

Contrary to later popular accounts, Holmes’s combat report did not describe a deliberate ramming. The incident nevertheless became embedded in public mythology as an emblem of desperate resistance.

The escort formations continued to suffer losses as the battle spread. At 12:30 hours, Sergeant D. G. S. R. Cox of No. 19 Squadron destroyed a Bf 109E-1 (W.Nr. 6147) of 2./JG 27. The aircraft crashed at Lodge Wood, Homestead, Isfield, near Uckfield, and Uffz. A. Walburger was captured.

At 12:42 hours, Flight Sergeant C. Sydney of No. 92 Squadron shot down a Bf 109E-1 (W.Nr. 3619) of 3./JG 53 over London. The aircraft force-landed at Grand Redoubt between Hythe and Dymchurch, and Uffz. K.-H. Feldmann was captured.

Shortly afterwards, at 12:45 hours, Pilot Officer J. F. J. MacPhail of No. 603 Squadron destroyed a Bf 109 of 2./JG 53 during combat over Maidstone. The aircraft crashed at Gore Wood, Aldington Court Farm, Bearsted, killing Oblt. R. Schmidt, who was later buried in St Mary’s churchyard, Thurnham.

Further losses followed. At 12:50 hours, a Bf 109E-4 (W.Nr. 1590) of 3./JG 53 was shot down over London by Flight Sergeant G. C. Unwin of No. 19 Squadron and Flying Officer A. D. Nesbitt of No. 1 (RCAF) Squadron. The aircraft crashed at Mullard Wood, Norheads Farm, Biggin Hill. Oblt. J. Haase baled out but was killed when his parachute failed to open.

KG 76’s formation had been shattered under continuous RAF attack. Six Dorniers were destroyed and many others badly damaged as the surviving bombers withdrew under increasingly limited escort. Among the losses was a Do 17Z (W.Nr. 2555, F1+FS) of 8./KG 76 equipped with an experimental flame-throwing device, which malfunctioned at altitude, spraying oil. At 12:10 hours, the bomber was brought down by Flying Officer J. C. Dundas and Pilot Officer E. Q. Tobin of No. 609 Squadron together with anti-aircraft fire while taking part in the raid on London’s docks. The aircraft force-landed at Castle Farm, Shoreham. Fw. S. Schmid was captured but later died of his wounds, while Fw. H. Pfeiffer, Fw. M. Sauter, and Fw. R. Heitsch were captured.

At 12:20 hours, another Do 17Z (W.Nr. 2578, F1+BS) of 8./KG 76, was shot down by Pilot Officer A. R. H. Barton of No. 253 Squadron and crashed into the sea off Herne Bay. The body of Fw. L. Keck later washed ashore at Herne Bay on 29 September, while Uffz. G. Rosenow’s body came ashore at Southwold on 15 October. Uffz. O. Zahn and Uffz. H. Heitmann were posted missing, believed killed.

At the same time, a Do 17Z (W.Nr. 2814, F1+AT) of 9./KG 76 was shot down over London by Flight Sergeant J. Komínek of No. 310 Squadron, Sergeants C. A. L. Hurry and G. W. Jefferys of No. 46 Squadron, and Pilot Officer V. M. M. Ortmans and Sergeant R. J. Ommaney of No. 229 Squadron. The aircraft crashed at Argos Hill Lodge, Red Lane Farm, Rotherfield. Obgfr. K. Böhme, Gefr. J. Kotone, and Lt. A. Wagner were killed, while Gefr. P. Holdenried attempted to bale out but became entangled in the tailplane and was also killed.

At 12:30 hours, a Do 17Z-2 (W.Nr. 3322, F1+DT) of 9./KG 76 was brought down during combat over London by Sergeant E. Tyrer of No. 46 Squadron, Flight Lieutenant R. F. Rimmer of No. 249 Squadron, Flight Lieutenant P. M. Brothers and Pilot Officer P. A. Mortimer of No. 257 Squadron, Sergeant E. W. Wright of No. 605 Squadron, and Pilot Officer H. N. Tamblyn of No. 242 Squadron. The aircraft crashed at Underriver, Sevenoaks. Oberfw. H. Streit, Fw. W. Seuffert, and Fw. W. Raab baled out and were captured, but Uffz. E. Malter was killed when his parachute fouled the aircraft.

Ten minutes later, a Do 17Z-3 (W.Nr. 2651, F1+FL) of 3./KG 76 was shot down by Pilot Officer J. R. B. Meaker of No. 249 Squadron, Flight Lieutenant W. J. Leather, Flying Officer T. D. Williams, and Pilot Officer P. S. C. Pollard of No. 611 Squadron, Flight Lieutenant K. McL. Gillies and Pilot Officer C. A. W. Bodie of No. 66 Squadron, and Flight Lieutenant J. W. Villa of No. 92 Squadron. The aircraft crashed at Alcrofts Farm, Sturry. Oberfw. K. Niebler, Fw. K. Wissmann, and Uffz. J.-F. Schatz were killed, while Oblt. K.-E. Wilke and Uffz. H. Zrenner baled out and were captured.

By 13:00 hours, the first phase of the battle had ended. Churchill, watching the plots clear from the operations table, expressed satisfaction as RAF squadrons returned to refuel and rearm. Of the Duxford Wing’s fifty-six aircraft, only forty-nine remained serviceable for the afternoon fighting.

13:45–15:45 Hours: The Afternoon Attack

Even as KG 76’s survivors landed in France, a far larger second wave was assembling. Bomber units from KG 2, KG 3, KG 26, and KG 53 took off to attack the London docks and industrial targets north and south of the Thames. In total, 114 bombers advanced in four columns, supported by a powerful fighter screen from JG 3, JG 26, JG 53, JG 77, and elements of LG 2 and ZG 26.

Chain Home detected the raid at 13:45 hours. Park ordered successive waves of interceptions, eventually committing nearly every available squadron. By 14:20 hours, the RAF had 276 fighters airborne, though the Germans still enjoyed a numerical advantage—particularly in Bf 109s.

Initial engagements erupted over Romney Marsh, where Spitfires of Nos. 41, 92, and 222 Squadrons clashed with JG 26.

At 14:20 hours, a Bf 109E-4 (W.Nr. 2803) of 9./JG 51 was shot down during combat with RAF fighters and crashed at Skinners Corner, Mascalls, near Paddock Wood, killing Lt. F. Klotz. Ten minutes later, Pilot Officer W. Cunningham of No. 19 Squadron brought down a Bf 109E-4 (W.Nr. 3266) of 7./JG 51 during combat near Dover. The fighter crashed at Nelson Park, St Margaret’s-at-Cliffe, and Lt. K. Bildau baled out and was captured.

At 14:45 hours, Flying Officer L. A. Haines of No. 19 Squadron destroyed a Bf 109E-7 (W.Nr. 2058) of 3./LG 2 during combat over London. The aircraft crashed at Shellness, and Uffz. A. Klick was captured.

Hurricanes from Nos. 213 and 607 attacked KG 3 head-on, followed by further assaults from Nos. 605 and 501 Squadrons. Despite losses, the Dorniers pressed on, reaching the Thames at 14:31 under heavy anti-aircraft fire.

At approximately 14:35 hours, Churchill stood beside Park in the Uxbridge operations room, watching as every squadron marker was committed. Turning to Park, he asked quietly,

“What other reserves have we?”

Park replied,

“There are none.”

The decisive fighting unfolded near Gravesend. Do 17s of KG 3 and He 111s of KG 26 were intercepted by Hurricanes from Nos. 17, 46, 249, 257, 504, and 603 Squadrons. Three Dorniers were destroyed in the opening attacks, including the aircraft of Hauptmann Ernst Püttmann. KG 53 and KG 2 were then engaged in turn by Spitfires and Hurricanes from Nos. 1 (RCAF), 66, 72, 73, 229, 253, and 303 Squadrons.

Cloud hindered interception accuracy but also obscured targets. At 14:45 hours, approximately 100 bombers dropped 120 tons of ordnance, concentrating on West Ham after failing to locate the Surrey Commercial Docks. The Bromley-by-Bow gasworks was badly damaged, Upton Park station was hit, and surrounding residential districts were devastated. Seventeen civilians were killed and more than a hundred injured.

As fuel reserves dwindled, the Bf 109 escorts began withdrawing, leaving the bombers increasingly exposed. The Dorniers of KG 3 suffered catastrophic losses.

At 14:23 hours, a Do 17Z-2 (W.Nr. 3294, 5K+DM) of 4./KG 3 was shot down by Pilot Officer A. E. Johnson of No. 46 Squadron, Pilot Officers H. P. Hill and D. G. Williams of No. 92 Squadron, Pilot Officer R. G. A. Barclay of No. 249 Squadron, Flying Officer B. van Mentz of No. 222 Squadron, Flying Officer P. S. Turner of No. 242 Squadron, and Flying Officer J. R. Hardacre of No. 504 Squadron. The aircraft crashed at Gladstone Road, Laindon Hills, Billericay. Lt. K. Dumler, Uffz. H. Maskolus, and Fw. A. Vogel were killed, while Uffz. G. Friebe baled out and was captured.

At 14:30 hours, a Do 17Z-2 (W.Nr. 4200, 5K+JN) of 5./KG 3 was rammed during combat over London by Pilot Officer T. P. M. Cooper-Slipper of No. 605 Squadron. The Dornier crashed into Widehurst Woods near Marden. Oberfw. E. Rilling baled out too low and was killed, while Oberfw. H. Howind, Oberfw. H. Hobel, and Fw. E. Zimmermann parachuted safely and were captured.

Fifteen minutes later, Squadron Leader J. Sample of No. 504 Squadron and anti-aircraft fire brought down a Do 17Z-2 (W.Nr. 3457, 5K+JM) of 4./KG 3 over London. The bomber crashed into houses in Perry Street near Barnehurst Golf Course, Dartford. Uffz. K. Hausburg baled out but was killed when his parachute failed to open, while Lt. H. Michaelis and Flgr. H. Bormann were captured. Uffz. W. Burbulla later died of wounds in Dartford Hospital.

At almost the same moment, a Do 17Z-3 (W.Nr. 2881, 5K+CM) of 4./KG 3 was shot down by Flight Lieutenant E. N. Ryder and Flying Officer J. G. Boyle of No. 41 Squadron, Flying Officer S. Fejfar of No. 310 Squadron, Pilot Officer R. Berry of No. 603 Squadron, and anti-aircraft fire. The aircraft force-landed at Lower Stoke on the Isle of Grain, and all four crew members were captured.

At 15:00 hours, a Do 17Z-2 (W.Nr. 1176, 5K+DN) of 5./KG 3 was shot down during combat over London and crashed into the Thames Estuary. Fw. K. Falke baled out and was captured, while Hptm. E. Püttmann and Oblt. A. Langenheim were posted missing, believed killed.

Fifteen minutes later, Pilot Officer P. J. T. Stephenson of No. 607 Squadron destroyed a Do 17Z-3 (W.Nr. 3458, 5K+GN) of 5./KG 3 during combat over the Thames. The aircraft crashed at Combwell Wood, Kilndown, near Goudhurst. Oblt. H. Becker-Ross, Oberfw. G. Bruckner, Fw. A. Hansen, and Fw. W. Brinkmann were all killed and later buried in All Saints Churchyard, Staplehurst.

KG 2 likewise suffered heavily as RAF squadrons attacked the withdrawing bombers across Kent and the Thames Estuary. At 14:45 hours, a Do 17Z-2 (W.Nr. 3230, U5+ET) of 9./KG 2 was shot down by Squadron Leader J. E. McComb, Flying Officers M. P. Brown and T. D. Williams, and Pilot Officer J. W. Lund of No. 611 Squadron. The aircraft crashed at Cranbrook. Uffz. R. Lenz, Uffz. O. Krummheuer, and Fw. H. Glaser were killed, while Uffz. J. Sehrt baled out and was captured.

At 15:05 hours, a Do 17Z (W.Nr. 3440, U5+PS) of 8./KG 2 was brought down by Sergeant R. A. Innes of No. 253 Squadron, Flying Officer R. W. Oxspring of No. 66 Squadron, Pilot Officer H. P. Hill of No. 92 Squadron, and anti-aircraft fire. The bomber crashed at The Chase, City Way, Chatham, and all four crew members baled out and were captured.

At 15:15 hours, Pilot Officer A. Lyall of No. 602 Squadron, Squadron Leader H. S. Darley, Flying Officer J. C. Dundas, and Pilot Officer M. E. Staples of No. 609 Squadron, together with Flight Lieutenant G. ff. Powell-Shedden of No. 242 Squadron, shot down a Do 17Z-3 (W.Nr. 2678, U5+CN) of 5./KG 2. The aircraft force-landed at Eighteen Pounder Farm, Westfield, near Hastings. Uffz. F. Reinisch, Oblt. U. Latz, and Fw. K. Haase were captured, while Oberfw. W. Hafner baled out and was believed to have drowned.

Another Do 17Z (W.Nr. 3405, U5+FT) of 9./KG 2 was shot down during combat over the Thames Estuary by Pilot Officer W. B. Pattullo of No. 46 Squadron and Pilot Officer B. G. Stapleton of No. 603 Squadron. The aircraft crashed into the sea off Herne Bay. The body of Uffz. H. Hoppe later washed ashore on the Isle of Sheppey, while Oberfhr. K.-O. Staib’s body was recovered at Graveney Marsh on 30 September. Gefr. A. Hoffmann and Gefr. J. Zierer were rescued by a Royal Navy launch.

The Heinkel formations of KG 26 and KG 53 likewise suffered severe losses as the fighting continued unabated. At 14:30 hours, Pilot Officer R. Mottram of No. 92 Squadron shot down a He 111H-2 (W.Nr. 5718, A1+LN) of 5./KG 53 during combat over London. The aircraft force-landed at Trafford Farm, Benenden. Fw. O. Maier and Gefr. A. Hoffmann were killed, while Lt. H. Bansch, Uffz. S. Bauer, and Uffz. E. Buttler were captured.

At 14:50 hours, Sergeant B. Furst of No. 310 Squadron and Flying Officer B. D. Russell of No. 1 (RCAF) Squadron brought down a He 111H-2 (W.Nr. 3140, A1+DA) of KG 53 during a bombing mission against Beckton Gasworks. The aircraft crashed at Woolwich Arsenal. Fw. A. Benz, Fw. A. Schweiger, Uffz. H. Meyer, and Uffz. G. Geiger were killed, while Fw. M. Cionber baled out badly injured and was admitted to the Royal Herbert Hospital.

Five minutes later, a He 111H-2 (W.Nr. 5120, A1+EL) of 3./KG 53 was shot down during a raid on London’s docks and force-landed at Horstead Hall, Botany Farm. Fw. F. Grotzki was killed, while Uffz. A. Gerding, Lt. H. Boeckh, Uffz. K. Altmann, and Obergefr. R. Kurzawski were captured.

At 15:00 hours, a He 111H-4 (W.Nr. 6985, 1H+IH) of 1./KG 26 was shot down over London by Squadron Leader E. A. McNab of No. 1 (RCAF) Squadron, Sub-Lieutenant A. G. Blake of No. 19 Squadron, Pilot Officer H. C. Baker of No. 41 Squadron, Pilot Officers A. C. Cochrane and P. A. Mortimer of No. 257 Squadron, and Sergeant E. M. C. Prchl of No. 310 Squadron. The bomber force-landed at Asplens Head, Foulness, and all five crew members were captured.

At the same time, a He 111H-1 (W.Nr. 2771, A1+AN) of 5./KG 53 was brought down during combat by a large concentration of RAF fighters, including aircraft from Nos. 1 (RCAF), 66, 92, 229, 238, 242, 249, and 504 Squadrons. The bomber force-landed at West Malling airfield. Obergefr. E. Sailler and Gefr. H. Lange were killed, while Uffz. O. Zilling, Fw. R. Lichtenhagen, and Fw. K. Behrendt were captured.

Thirty minutes later, Pilot Officer H. P. Hill of No. 92 Squadron shot down a He 111H-2 (W.Nr. 5481, A1+GL) of 3./KG 53 over London. The aircraft crashed at Bourne Farm, Sandhurst. Uffz. A. Lehner and Fw. K. Rothig were killed, while Oblt. G. Buchner, Gefr. H. Stamminger, and Gefr. H. Richter baled out and were captured.

Meanwhile, RAF fighters continued to inflict losses on the withdrawing escorts. At 15:00 hours, Pilot Officer D. W. Crowley-Milling of No. 242 Squadron shot down a Bf 109E-1 (W.Nr. 2685) of 1./JG 3 over London. The aircraft crashed at St Michael’s, Tenterden, and Oberfw. F. Hessel baled out and was captured.

At the same time, a Bf 109E-7 (W.Nr. 2061) of 1./LG 2 was brought down over London by Sergeant M. Wojciechowski of No. 303 Squadron and Sergeant G. J. Bailey of No. 603 Squadron. The fighter crashed at Hartlip Churchyard, Rainham, and Uffz. H. Streibing baled out and was captured.

At 15:15 hours, a Bf 110C-3 (W.Nr. 3802, L1+IH) of 13./LG 1 was shot down during combat with RAF fighters and crashed at Rippers Cross, Hothfield Farm, Ashford. Oblt. H. Müller was killed, while Fw. A. Hoffmann later died of his wounds.

Fifteen minutes later, a Bf 109E-4 (W.Nr. 1606) of 3./JG 3 was shot down by RAF fighters and crashed at Thorn Farm, Pluckley Brickworks. Oblt. H. Reumschüssel baled out and was captured. Another fighter lost during the withdrawal was a Bf 109E-4 (W.Nr. 3759) of 1./JG 77, which crashed at Stutfall Castle, Lympne, killing Oblt. H. Kunze.

By 15:45 hours, the surviving formations were streaming back across the Channel in disarray.

At 16:00 hours, Pilot Officer D. G. Williams of No. 92 Squadron, together with anti-aircraft fire, brought down a He 111H-3 (W.Nr. 6843, A1+GM) of 2./KG 53. The aircraft crashed at Peasridge Farm, Frittenden, near Staplehurst. Major M. Gruber, Oblt. H.-P. Schierning, Fw. M. Nagl, and Oberfw. G. Schmidt baled out and were captured, while Fw. A. Grassi was killed.

KG 2 lost eight Do 17s, KG 3 a further six, while KG 53 suffered the loss of six He 111s, including the aircraft of Major Max Gruber. Although RAF claims greatly exceeded the Luftwaffe’s actual losses, German casualties were nevertheless severe.

Other Daylight and Evening Raids

At approximately 15:00 hours, more than twenty unescorted He 111s from III./KG 55 attempted an attack on naval targets at Portland. They were intercepted by Spitfires of No. 152 Squadron, suffering losses while inflicting only minor damage.

At 17:40 hours, aircraft from Erprobungsgruppe 210 attacked Southampton, aiming at the Spitfire factory at Woolston. Despite intense anti-aircraft fire, the factory escaped destruction, though nearby residential areas and infrastructure were damaged, causing civilian casualties.

Further minor reconnaissance and nuisance raids occurred into the evening.

Enemy Action by Night

Night bombing began at 22:48 hours when KG 27 attacked Liverpool, causing widespread damage but relatively few casualties. Additional raids struck Eastbourne, Worthing, Bournemouth, Cardiff, Bristol, Manchester, and towns across the Midlands and North West. RAF night fighters flew 64 sorties and intercepted several aircraft but achieved no confirmed victories.

Summary

Sunday, 15 September 1940, was a decisive turning point in the Battle of Britain. Fighter Command, fully committed, had repelled two of the largest coordinated attacks of the campaign. The Luftwaffe suffered unsustainable losses. Hitler’s assumption that the RAF was on the verge of collapse was conclusively disproved. Operation Sea Lion was postponed indefinitely.

This day—later commemorated as Battle of Britain Day—marked the moment when the strategic initiative in the air war shifted firmly to Britain. As Churchill watched from the operations room at Uxbridge, he understood the significance. Britain had not only survived—it had fought back and won.

3. The final moments of Dornier Do 17Z-2 ‘F1+FH’ (Wk-Nr 2361) of 1.Staffel/KG 76, brought down by Sergeant Ray Holmes of No. 504 Hurricane Squadron on 15 September, 1940.
4. Soldiers survey the carnage after a Dornier Do 17 bomber crashed onto the forecourt of Victoria Station following a mid-air collision with Sergeant Ray Holmes’ Hurricane on 15 September 1940 over central London. The shop of well-known clock supplier James Walker Ltd was badly damaged and a mass of mantel clocks are scattered across the pavement.
5. The wreckage of the Hurricane that collided with a Dornier Do 17 bomber on 15 September 1940, is placed near Buckingham Palace Road in central London. The crater that contained the Rolls-Royce Merlin engine and other wreckage was simply filled in and covered over. In 2004, the engine was recovered during a televised archaeological dig in the presence of its former pilot, Sergeant Ray Holmes of No. 504 Squadron, who had bailed out of the aircraft after colliding with the German bomber.

7. Dornier Do 17Z (F1+FS) of 8./KG 76, flown by Feldwebel Rudolf Heitsch, force-landed at Castle Farm near Shoreham on 15 September 1940 after a low-level chase by No. 609 Squadron Spitfires flown by Flight Lieutenant Dundas and Pilot Officer Tobin. The bomber, part of a formation intercepted over Kent, narrowly missed power cables before coming down. Its crew were captured by the Home Guard: Heitsch and his observer were unhurt, the gunner wounded, and the wireless operator fatally injured. The aircraft was fitted with a tail-mounted flamethrower intended to deter pursuers, though it malfunctioned, spraying only oil. A local hop picker was also wounded by stray fire.
