By August 1940 the first phase of the Battle of Britain was drawing to a close as the Luftwaffe’s attempts to draw the RAF out with small scale attacks had failed to succeed. The second phase began on August 13th when Luftflotten 2,3 and 5 began a series of massive air attacks aimed at RAF air bases and the vital network of radar installations which provided them with the critical early warning of impeding attack. The Luftwaffe had at this time some 1100 fighters and 1300 bombers; opposing this the RAF had a mere 675 fighters.

Around midday on August 18th, Luftflotte 2 launched a huge series of attacks which would make up a significant proportion of the 850 or so sorties launched by the Luftwaffe on that day. RAF Biggin Hill and RAF Kenley were both targeted by a wave consisting of some 108 bomber and 150 fighters. The majority of the inbound raid was detected by Britain’s radar network. Nine squadrons were vectored out to meet the inbound raiders.

Meanwhile, in the vicinity of Biggin Hill, a huge dogfight was developing as No.615 Squadron’s Hurricanes were bounced by Bf109s of JG3; however, the ensuing combat allowed No.32 Squadron’s Hurricanes to smash into the main bomber force. The head on attack succeeded in breaking up the entire formation of Dorniers.

By this time Ju88s of KG76 had arrived at Kenley but found their target obscured by smoke from the damage caused by an earlier low level attack. They too were attacked by RAF fighters. Simultaneously, KG1’s Heinkel 111s were approaching Biggin Hill. Escorting Bf109s broke away to intercept approaching Spitfires of No.615 Squadron, succeeding in keeping the British fighters at bay to allow the bombers a clear run to the target. However, the only damage was to the station golf course. Airfields at Croydon and Manston were also attacked as secondary targets. A further wave of 109s was sent to protect the retreating German force, but this took heavy losses.

Luftflotte 3 were the next to enter the fray with over 100 Junkers 87 Stukas of StG77and StG3. The dive bombers launched to attack airfields at Thorney Island, Gosport and Ford, as well as targeting Poling radar station, escorted by 157 Bf109s of JG2, JG27 and JG53. After underestimating the size of the raid only 68 British fighters were scrambled to intercept. Some 300 aircraft swirled in a huge dogfight in the ensuing melee whilst the Stukas still continued to bomb their assigned targets under fire from enemy fighters and AA.

By early evening, Luftflotte 2 had reassembled and was ready for another strike. The final big push against Fighter Command came in the form of 58 Dornier 17s of KG2 and 51 Heinkel 111s of KG53, attacking RAF Hornchurch and RAF North Weald respectively. Escorting them were 140 German fighters. 13 Squadrons of Hurricanes and Spitfires were scrambled from 11 Group to intercept, with a further four sent to assist from 12 Group to the North. British fighters tore through the ranks of KG53’s Heinkels, scattering the raid and forcing many of the German bombers to jettison their payloads and flee.

Whilst the Luftwaffe continued to launch raids over Britain after dark, the brunt of the fighting on August 18th was now over. In terms of aircraft losses, the Luftwaffe lost some 35 fighters and 30 bombers whilst the RAF lost 31 aircraft, but critically only 10 pilots.

However, the Luftwaffe’s objective was to destroy the RAF on the ground as well as in the air and in that respect they had achieved other notable successes throughout the day. The propaganda machines of both nations claimed approximately double the successes they had actually achieved in terms of aircraft destroyed, whilst also only admitting to about half the losses suffered. However, both sides had experienced their greatest losses in a single day for the entire campaign in what would become known as ‘The Hardest Day’.
