Today we remember the recognised climax of the Battle of Britain.
70 Years ago, on Sunday the 15th of September 1940, it was a highly significant day when the RAF had all their fighter squadrons, including all reserves, in the air to meet what is considered to be the last mass determined attack by the Luftwaffe to destroy the RAF resistance and launch a German land and sea invasion. The Battle was not over, for it would last until the end of October 1940 but this day generally represents the true climax of the conflict.
On that Sunday the battle statistics are now known to be:
Sunday, 15th September, 1940**
RAF
Aircrew Losses Aircraft Lost
16 31
Luftwaffe
93 61
These figures do not allow for those German aircraft who would have limped back across the Channel with burnt out engines, smashed under-carriages, dead crew, that either finally went into the drink, or crash landed. Others may have landed on their wheels, with dead crew inside, and with their airframes heavily damaged, never to fly again. Therefore the German overall losses would be greater than the figures shown for over the UK.
This was not the worst day for the Luftwaffe, as on the 15th August 1940 the statistics** were:
RAF
Aircrew Losses Aircraft Lost
11 35
Luftwaffe
128 76
However, the trend had been the same basically throughout the battle. Although the RAF had suffered some terrible days of losses, for the Luftwaffe crews it just seemed, and was, far worse. Their High Command repeatedly told them the RAF were within 4/5 days of collapse, that certain squadrons had been totally annihilated, yet those very squadrons were still attacking them, and in some numbers. The British fighters were always there to intercept them and cause them heavy losses.
After that the Luftwaffe concentrated their attacks at night on London, and most major cities of Britain which had already commenced on the 7th September, and lasted until May 1941.
Thankfully for Great Britain, and the World, from 22nd June 1941 Hitler's interests lay elsewhere - Operation BARBARROSA - to conquer Russia, and from that moment the Nazi dream of world domination was doomed. Great Britain had survived the greatest of threats, and early defeats, to go on and gain victory thanks to the bravest of young men who gave their lives for our today.
537 RAF airmen died, but 2,662 Luftwaffe airmen were killed**. This was from 1,023 RAF aircraft lost, compared to 1,887 German planes lost. In these figures you will see why the morale of the Luftwaffe crews in their squadrons was shattered, and they lost the Battle based on more than physical losses alone.
But on this day we should also remember the young men of the Luftwaffe who were lost, along with all those of the RAF who had been obeying orders and given their lives for a cause most believed in.
As my London East End Gran, who had suffered during the Blitz, often stated when seeing either a British or German plane going down "That is some mothers son"

Let us remember they gave their today for our tomorrow.
