1968: North Vietnam Offensive

During the war in Vietnam, Marines defended a base at Khe Sanh, a remote but strategic outpost near the Laotian border.  
 
The North Vietnamese army attacked the base, predicting overwhelming victory. The base remained under siege for 77 days, but Marines prevented the enemy from penetrating United States defenses.  
 
The victory was a morale boost for U.S. forces in what proved to be a long struggle for peace.
