German Halt at Dunkirk
German army had little amphibious experience
• Looked at the Channel as a barrier
• Didn’t believe British could possibly get away
Panzer units arrived well ahead of the infantry
• Were exhausted, out of supply
• Called halt to rest, resupply, allow infantry to catch up
Luftwaffe hadn’t gotten much credit in battle
• Asked for and received permission to destroy BEF
British saw Channel as a highway - organized evacuation

Battle of Britain
Background
Operation Seelöwe (Sealion)
Operation Seelöwe
Invasion barges in Channel ports
July 1940
Operation Sealion
Germans began planning for invasion
in November 1939
Initial criteria for success:
* The Royal Navy had to be eliminated.
* The Royal Air Force (RAF) air strength had to be eliminated.
* British coastal defenses had to be destroyed.
* British submarine action against landing forces had to be prevented.
First Law of Modern War
The air battle must be won if the war is to be won.
General of the Army Omar Bradley
November 1951
USAF Doctrine
(modern)
Priorities for tactical (theater) airpower:
1. Air Superiority
2. Interdiction
3. Close Air Support
Operation Sealion
Defeat of the Royal Navy in the invasion area
required control of the air
Hitler’s conditions for Sealion:
The RAF is to be "beaten down in its morale and in fact, that it can no
longer display any appreciable aggressive force in opposition to the
German crossing".
Warning Order for Seelöwe, 16 July 1940
Operation Sea Lion
1940
German Plan
Take control of the air
 Defeat the RAF
Isolate the invasion area
 Neutralize Royal Navy, destroy communications & defenses
Invade England
 Land Panzers to employ Blitzkrieg tactics
