The Autobahn is the freeway system built during the reign of the Third Reich. Employing 100,000 Germans during the 1930s depression, the Autobahn became an essential part of the infrastructure for the German military during World War II.
Staging areas for new troops arriving in the ETO (European Theater of Operations), were known as "Cigarette Camps". Each camp was named after a brand of cigarette for security reasons. Referring to camps without any indication of geographical location help to block information leaks to the enemy. After V-E Day (Victory in Europe) the camps were converted to redeployment centers. An estimated 3 million American troops either entered or left Europe through the Le Havre area camps.
