U.S. Army Corps of Engineers: A Unit Study

The U.S. Army Corps of Engineers was established on June 16, 1775, by the Continental Congress to serve General George Washington.  General Washington appointed a Chief Engineer, Colonel Richard Gridley, considered the founding father of the Corps, who was responsible for building the batteries above the city of Boston that played a large role in the British evacuation of that city.  It was in 1802 that Thomas Jefferson formally organized an Army Corps of Engineers stationed at West Point.

The Army Corps of Engineers Mission

Today the mission of the Army Corps of Engineers is to “provide vital public engineering services in peace and war to strengthen our Nation’s security, energize the economy, and reduce risks from disasters.” The Engineers are responsible for planning, designing, and building flood protection systems, military facilities, and locks and dams and other structures necessary for water navigation and flood control.  They have taken on such varied tasks as surveying the American West, and building the Washington Monument, the Lincoln Memorial, the Library of Congress,  the Pentagon, Veterans Administration hospitals, missile sites, and NASA facilities.  That also assisted in the completion of  the Panama Canal.  All Corps of Engineers projects are authorized by Congress.
