The Devon and Cornwall County Division was a County Division of the British Army created during the Second World War. It was formed on 28 February 1941, from recently recruited soldiers, in response to the renewed threat of a German invasion. The 10,000-strong division was a static formation, lacking transport, intended to defend possible landing sites along the southern Cornish and Devon coastlines from invading German troops. The creation of the division also helped to free up the more experienced troops, who were then held back from the coastline to be able to launch a counterattack against any potential German landings.
During mid-1941, Germany launched a massive invasion of the Soviet Union, which practically eliminated the threat of an invasion of the United Kingdom. Consequently, the division never saw service in its intended role. With the threat of a German invasion lifted, the British Army began a series of reforms intended to restore balance to the then infantry-heavy organisation. As a result, all nine county divisions were disbanded. The Devon and Cornwall County Division ceased to exist on 1 December, but was subsequently reformed as the 77th Infantry Division.
