Decisive WWII action.
Had the British lost, Hitler would have invaded Britain
and that would have changed everything, for the worse. In the spring of 1940 Hitler looked
invincible. He had conquered and
occupied Poland, Denmark, Norway, Belgium, The Netherlands, France (a great
power) and driven the British (the other great power) into the sea at Dunkirk. Although the British had managed to rescue
most of their soldiers, they abandoned all their tanks, trucks, artillery,
tents, rations, and ammunition. Only a few troops retained their rifles. Had Hitler been able to put a few divisions
ashore in England
in the summer of 1940, it would have been all over for the Brits.
Only the Royal Navy
stood in the way. Had the Germans set
out for England
in their fleet of Rhine River
barges, the Brits would have steamed up along side in destroyers and blown the
Germans out of the water. The Brits had
better than 100 destroyers backed up by 30 odd cruisers and a dozen
battleships. They had sunk Graf Spee and Bismarck. The actions off Norway
had wiped out most of the German destroyers.
Those river barges would have been on their own crossing the
channel.
The German
Luftwaffe might have been able to drive the Royal Navy away and safe guard the
crossing. For this to work, the
Luftwaffe had to establish air superiority.
You cannot be attacking RN destroyers with Spitfires on your tail. This means shooting down RAF fighters in the
air and bombing RAF bases out of operation.
The Brits knew what
was coming. They had invented and
installed the first modern air defense system.
We were still using the idea in USAF in the 1960s. It consisted of ground radar, linked by
telephone to “sector stations” which scrambled the fighters and gave them
vectors and altitudes to fly for interception.
Without the radar Luftwaffe strikes would have surprised the
RAF on the ground unless the RAF flew reconnaissance sorties to spot the
Germans at a distance. The number of
recon sorties would have huge. A fighter
unit can only put up so many sorties a day.
To waste all those sorties just flying around looking for the enemy
would have meant the end for the British.
With the radar, the British fighters could stay on their fields, all
fueled and armed, ready to scramble, and count on intercepting the Germans on
pretty much every sortie. No sorties
wasted flying recon.
Had the Germans
figured things out, they could have bombed the radar stations. There were easy to find, being right on the
coast and having 300 foot high antennas marking their positions. And they could have bombed out the sector
stations by homing in on their radio transmissions. But, the Germans never figured out what was
going on and let the radars and the sector stations operate undisturbed. They counted on shooting down the Hurricanes
and Spitfires in the air, and bombing their fields. This didn’t work out because the British
planes and pilots were as good as the Luftwaffe planes and pilots, and the
British cranked up their aircraft factories and were building more planes than
the Germans were shooting down.
Why do we care? England
was a Great Power; she had 50 odd million population. Not too shabby even compared to our 100 odd
million back then. And England
could count on solid support from Canada,
Australia, New
Zealand, South
Africa, and India. India
put up many of the troops that beat Rommel in North Africa,
and later beat the Japanese at Imphal and drove them out of Burma. And, England
was the base for the air war on Germany
and for launching D-Day. Many of the
craft that landed in Normandy
were open landing craft. They could
cross the Channel in good weather but they would never survive crossing the North
Atlantic even in summer. In
short England
was key strategic terrain. Had the
Germans taken it in 1940 it is difficult to imagine how we would ever have been
able to beat Hitler.
