The British County Divisions of the Second World War were raised by the British Army in 1941 as a defence against a planned German invasion of Britain. They were static formations which were supposed to command the Independent Infantry Brigades (Home) which were on anti-invasion duties. Each coast in danger had its own County Division.
The divisions were:
- Devon and Cornwall County Division
- Dorset County Division
- Durham and North Riding County Division
- Essex County Division (formerly the West Sussex County Division)
- Hampshire County Division
- Lincolnshire County Division
- Norfolk County Division
- Northumberland County Division
- West Sussex County Division (later, the Essex County Division)
- Yorkshire County Division
These formations had none of the usual divisional units that other permanent divisions had. Any they commanded were temporarily on loan from other formations.
