Overview
The Red Ball Express was a famed truck convoy system that supplied Allied forces moving quickly through Europe after breaking out from the D-Day beaches in Normandy in 1944. To expedite cargo shipment to the front, trucks emblazoned with red balls followed a similarly marked route that was closed to civilian traffic. The trucks also had priority on regular roads.
Conceived in an urgent 36-hour meeting, the convoy system began operating on August 25, 1944. Staffed primarily with African-American soldiers, the Express at its peak operated 5,958 vehicles that carried about 12,500 tons of supplies a day. It ran for 83 days until November 16, when the port facilities at Antwerp, Belgium, were opened, enough French rail lines were repaired, and portable gasoline pipelines were deployed.
History
Use of the term "Red Ball" to describe express cargo service dated at least to the end of the 19th century. Around 1892, the Santa Fe railroad began using it to refer to express shipping for priority freight and perishables. Such trains and the tracks cleared for their use were marked with red balls. The term grew in popularity and was extensively used by the 1920s.
The need for such a priority transport service during World War II arose in the European Theater following the successful Allied invasion at Normandy in June 1944. To hobble the German army's ability to move forces and bring up reinforcements in a counter-attack, the Allies had preemptively bombed the French railway system into ruins in the weeks leading up to the D-Day landing.
