Trapped on the beach

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

Operation Seelöwe

Invasion barges in Channel ports

July 1940

Operation Sealion

* 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.

Germans began planning for invasion in November 1939

Initial criteria for success:

First Law of Modern War

The air battle must be won if the war is to be won.

General of the Army Omar BradleyNovember 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
