Nothing happens until something moves.
The United states Army Transportation Corps is one of the Army's youngest service branches, having been established in 1942. However, the origin of its role extends far back to the Revolutionary War when in the crucial campaign General George Washington used animal-driven transportation to move American and French forces from the Hudson Valley to Yorktown, more than 450 miles away. So important was transportation in the American Revolution that Washington advised Congress to establish the position of Wagonmaster General to provide the Army's essential mobility. With the Civil War came the extensive use of the military railway service in moving troops to battle. The importance of transportation for the military increased rapidly as the U.S. Army Transport Service appeared during the Spanish American War and subsequently the Transportation Service was created in World War I. During this war, the Transportation Service carried 2 million men and their supplies to make them a fighting force across 3,000 miles of ocean.
