This article is designed only as a short introduction to the topic of Operation Sealion. At some stage, the author intends to write a much more detailed series of articles about this plan, as well as the plans for British defence against such an invasion and the plans for resistance in the event of occupation.
The evacuation of the BEF from Dunkirk had left the Wehrmacht in control of the Channel Coast after the fall of France and while this was an enviable position to be in, it meant that the Germans were now forced to contemplate what to do about what the Chief of Luftwaffe Intelligence called 'the most dangerous enemy'. The dire state of the British Army after the evacuation from the continent demanded immediate attention and while it would take time for reorganise and re-equip the ground forces available; they could only get stronger as went on.
Arguments still rage to this day as to how serious Hitler actually was, in contemplating an amphibious invasion of Britain, but whatever the case, the preparations that were made were conducted in a serious manner and involved a considerable cost to the German war effort.
Whatever their actual chances of success, the landings were planned as a contingency and were dependent on the efforts of the Luftwaffe to achieve air superiority over the landing area and much of southern Britain, in order German invasion of britain simulation dating forestall both the RAF and Royal Navy intervening in the operation.
The timeline of events relating to Sealion is as follows:. The main planning for the operation came out of two directives from Hitler and a supplemental one from the OKW, the first of which was issued on 16 July While the Heer found the idea appealing, rivers are not tidal, are not subject to severe weather and don't have the enemy's Home Fleet in a position to contest the crossing.
Following this was a meeting between Hitler, von Brauchitsch, and General der Artillerie Franz Halder the Army Chief of Staff on 13 Julywhere Halder presented more detailed planning proposals that outlined an operation incorporating 39 divisions and aroundmen published 20 July. Hitler authorised continued preparations but was puzzled over the lack of peace feelers from German invasion of britain simulation dating, as he once again outlined that he would prefer a negotiated settlement as he did not wish to hand Britain a military defeat which would disrupt the empire and only be of benefit to Japan and the USA.
Hitler also reviewed his decision to reduce the size of the army by thirty-five divisions to release additional manpower for the economy and scaled it down to a reduction of fifteen divisions.
The aim of this operation is to eliminate Great Britain as a base of operations from which the war against Germany can be fought and, if necessary, the island will be completely occupied. The Luftwaffe would eliminate the RAF as an effective fighting force and interdict the Royal Navy should it try to intervene and the Kriegsmarine would furnish an invasion fleet and protect it. Current army "German invasion of britain simulation dating" would form the basis of the operation, although the line would be German invasion of britain simulation dating slightly to between Ramsgate and the Isle of Wight.
In some ways, it seemed that the Luftwaffe was expected to almost defeat Britain by itself. Goring and his commanders however, mostly ignored the directive and continued with their own plans - they thought an invasion was going to be unnecessary anyway, while Raeder and the Kriegsmarine thought that OKW was insane. From this point, the Heer continued to be the main supporter of the plan, with the Luftwaffe lukewarm to the idea and the Kriegsmarine trying to torpedo the Heer's plan.
Following Fuhrer Directive No. On 28 Julythey proposed that if the invasion were to go ahead that a beachhead be established near Dover, the closest point to the continent, where a narrow corridor could be protected by minefields to each side as well as groups of U-Boats and E-Boats beyond these.
The Kriegsmarine estimated it would take ten days to put the first wave ashore and needless to say, the Heer was horrified. It had wanted landings all along the south coast from Folkestone to.
Brighton with a separate landing from Cherbourg. German invasion of britain simulation dating wanted wheeled and tracked vehicles and so all the car ferries were to be used along with all the cross-channel tourist facilities. The first wave was to be landed over three to four days and consist ofmen, 30, vehicles and 60, horses. This was followed by a memo dated 31 Julywhich advised that given the Kriegsmarine's preparations were complete by 15 Septemberthe dates most suitable for invasion would be from 22 - 26 September, when the weather was often bad.
It could not however, guarantee to able to protect the invasion from the Royal Navy and would not be able to guarantee resupply if there was indeed bad weather.
It was suggested that the invasion was put off until May when additional surface assets would be available and additional work be able to be carried out on converting or building vessels to allow for amphibious operations. It also stated that all preparations for invasion would be completed by 15 Septemberthe original deadline being kept as Hitler was concerned over the strength of the British Army if the invasion was postponed until the following spring.
Despite misgivings, the Kriegsmarine continued to scour the waterways. Mid-September saw the Kriegsmarine complete its assembly of the vessels to be used in the initial lift, as well as the finalisation of the German forces to be used see Figures 2 and 3the assault routes to be taken see Figures 4 and 7as well as German invasion of britain simulation dating plans for occupation see Figures 5 and 6.
