Hamburger hill battle tour is designed by our special arrangement of Viet Linh Travel. It brings you a recall memory of the war. The Battle of Hamburger Hill during the Vietnam War, also known as Hill 937. The battle, which was fought on May 10-20, 1969 was a direct assault against a heavily defended and strategically insignificant hill, resulted in over 400 U.S. casualties and caused an outrage back home. Hamburger Hill battle had run afoul of a fundamental war-fighting equation and the expenditure of effort at Hamburger Hill exceeded the value the American people attached to the war in Vietnam.
