 Hi all,
 
 War is won by logistics! [;)]
 
 Germans could have trid the Sealion invasion and they might have succesfull landing in England - but they would be doomed there because the landed troops would eventually run out of ammo, fuel and supplies... [:D]
 
 The Germans never had Mullbery harbours - they simply had to rely on capturing some ports in England - and to think that such port would be able to be defended agianst everything British would have thrown against it is impossible dearm for Germans!
 
 BTW, there is one nice war game conducted in the, I think 1970's...

 The full text is in 'Sealion' by Richard Cox. The scenario
 is based on the known plans of each side, plus previously
 unpublished Admiralty weather records for September 1940.
 Each side (played by British and German officers respectively)
 was based in a command room, and the actual moves plotted
 on a scale model of SE England constructed at the School
 of Infantry. The panel of umpires included Adolf Galland,
 Admiral Friedrich Ruge, Air Chief Marshal Sir Christopher
 Foxley-Norris, Rear Admiral Edward Gueritz, General Heinz
 Trettner and Major General Glyn Gilbert.
 
 The main problem the Germans face is that are a) the
 Luftwaffe has not yet won air supremacy; b) the possible
 invasion dates are constrained by the weather and tides
 (for a high water attack) and c) it has taken until
 late September to assemble the necessary shipping.

 BB = Battleship
 CV = Aircraft Carrier
 
 22nd September - morning
 The first wave of a planned 330,000 men hit the beaches
 at dawn. Elements of 9 divisions landed between
 Folkestone and Rottingdean (near Brighton).
 In addition 7th FJ Div landed at Lympne to take the airfield.
 
 The invasion fleet suffered minor losses from MTBs during
 the night crossing, but the RN had already lost one
 CA and three DDs sunk, with one CA and two DDs damaged,
 whilst sinking three German DDs. Within hours of the landings
 which overwhelmed the beach defenders, reserve formations
 were despatched to Kent. Although there were 25 divisions
 in the UK, only 17 were fully equipped, and only three
 were based in Kent, however the defence plan relied on
 the use of mobile reserves and armoured and mechanised
 brigades were committed as soon as the main landings were
 identified.
 
 Meanwhile the air battle raged, the Luftwaffe flew 1200
 fighter and 800 bomber sorties before 1200 hrs. The RAF
 even threw in training planes hastily armed with bombs,
 but the Luftwaffe were already having problems with their
 short ranged Me 109s despite cramming as many as possible
 into the Pas de Calais.
 
 22nd - 23rd September
 The Germans had still not captured a major port, although
 they started driving for Folkestone. Shipping unloading
 on the beaches suffered heavy losses from RAF bombing
 raids and then further losses at their ports in France.
 
 The U-Boats, Luftwaffe and few surface ships had lost
 contact with the RN, but then a cruiser squadron with
 supporting DDs entered the Channel narrows and had to
 run the gauntlet of long range coastal guns, E-Boats
 and 50 Stukas. Two CAs were sunk and one damaged. However
 a diversionary German naval sortie from Norway was
 completely destroyed and other sorties by MTBS and DDs
 inflicted losses on the shipping milling about in the
 Channel. German shipping losses on the first day
 amounted to over 25% of their invasion fleet, especially
 the barges, which proved desperately unseaworthy.
 
 23rd Sept dawn - 1400 hrs.
 The RAF had lost 237 planes out 1048 (167 fighters and
 70 bombers), and the navy had suffered enough losses such
 that it was keeping its BBs and CVs back, but large
 forces of DDs and CAs were massing. Air recon showed a
 German buildup in Cherbourg and forces were diverted to
 the South West.
 
 The German Navy were despondant about their losses,
 especially as the loss of barges was seriously
 dislocating domestic industry. The Army and Airforce
 commanders were jubilant however, and preperations for
 the transfer of the next echelon continued along with
 the air transport of 22nd Div, despite Luftwaffe losses
 of 165 fighters and 168 bombers. Out of only 732 fighters
 and 724 bombers these were heavy losses. Both sides
 overestimated losses inflicted by 50%.
 
 The 22nd Div airlanded successfully at Lympne, although
 long range artillery fire directed by a stay-behind
 commando group interdicted the runways. The first British
 counterattacks by 42nd Div supported by an armoured
 brigade halted the German 34th Div in its drive on Hastings.
 7th Panzer Div was having difficulty with extensive
 anti-tank obstacles and assault teams armed with sticky
 bombs etc. Meanwhile an Australian Div had retaken
 Newhaven (the only German port), however the New Zealand
 Div arrived at Folkestone only to be attacked in the
 rear by 22nd Airlanding Div. The division fell back on
 Dover having lost 35% casualties.
 
 Sep 23rd 1400 - 1900 hrs
 Throughout the day the Luftwaffe put up a maximum effort,
 with 1500 fighter and 460 bomber sorties, but the RAF
 persisted in attacks on shipping and airfields. Much of
 this effort was directed for ground support and air
 resupply, despite Adm Raeders request for more aircover
 over the Channel. The Home Fleet had pulled out of air
 range however, leaving the fight in the hands of 57 DDs
 and 17 CAs plus MTBs. The Germans could put very little
 surface strength against this. Waves of DDs and CAs
 entered the Channel, and although two were sunk by U-Boats,
 they sank one U-Boat in return and did not stop. The German
 flotilla at Le Havre put to sea (3 DD, 14 E-Boats) and at
 dusk intercepted the British, but were wiped out, losing
 all their DDs and 7 E-Boats.
 
 The Germans now had 10 divisions ashore, but in many
 cases these were incomplete and waiting for their
 second echelon to arrive that night. The weather
 was unsuitable for the barges however, and the decision
 to sail was referred up the chain of command.
 
 23rd Sep 1900 - Sep 24th dawn
 The Fuhrer Conference held at 1800 broke out into bitter
 inter-service rivalry - the Army wanted their second
 echelon sent, and the navy protesting that the
 weather was unsuitable, and the latest naval defeat
 rendered the Channel indefensible without air support.
 Goring countered this by saying it could only be done
 by stopped the terror bombing of London, which in turn
 Hitler vetoed. The fleet was ordered to stand by.
 
 The RAF meanwhile had lost 97 more fighters leaving only
 440. The airfields of 11 Group were cratered ruins, and
 once more the threat of collapse, which had receded in
 early September, was looming. The Luftwaffe had lost
 another 71 fighters and 142 bombers. Again both sides
 overestimated losses inflicted, even after allowing for
 inflated figures.
 
 On the ground the Germans made good progress towards Dover
 and towards Canterbury, however they suffered reverses
 around Newhaven when the 45th Div and Australians
 attacked. At 2150 Hitler decided to launch the second wave,
 but only the short crossing from Calais and Dunkirk. By
 the time the order reached the ports, the second wave
 could not possibly arrive before dawn. The 6th and 8th
 divisions at Newhaven, supplied from Le Havre, would not
 be reinforced at all.
 
 Sep 24th dawn - Sep 28th
 The German fleet set sail, the weather calmed, and U-Boats,
 E-Boats and fighters covered them. However at daylight 5th
 destroyer flotilla found the barges still 10 miles off
 the coast and tore them to shreds. The Luftwaffe in turn
 committed all its remaining bombers, and the RAF responded
 with 19 squadrons of fighters. The Germans disabled two
 CAs and four DDs, but 65% of the barges were sunk. The
 faster steamers broke away and headed for Folkestone,
 but the port had been so badly damaged that they could
 only unload two at a time.
 
 The failure on the crossing meant that the German
 situation became desperate. The divisions had sufficient
 ammunition for 2 to 7 days more fighting, but without
 extra men and equipment could not extend the bridgehead.
 Hitler ordered the deployment on reserve units to Poland
 and the Germans began preparations for an evacuation as
 further British arracks hemmed them in tighter. Fast
 steamers and car ferries were assembled for evacuation
 via Rye and Folkestone. Of 90,000 troops who landed
 on 22nd september, only 15,400 returned to France, the rest
 were killed or captured.
 
 
 
 Leo "Apollo11"
 
 
 By the way Apollo, the plan in this drawing was the original Army plan which was rejected by the Navy as impossible and replaced by a much narrow front plan basically only going as far as Beachy Head (so anything West of Beachy Head was scrapped and a much higher concentration was allotted to the remaining invasion beaches). Please note, this would  have drastically reduced ferry times (closer to embarkation ports in France) and would have put all invasion beaches very close to German fighter bases in France.
