The 18th Division was an infantry division in the III Corps of the Army of the Republic of Vietnam (ARVN). The U.S. Military Assistance Command Vietnam considered the 18th as undisciplined and was well known throughout the ARVN for its "cowboy" reputation. In 1975 the 18th was made famous as the only ARVN division that stood fast and refused to surrender before Saigon fell.
During the last major battle of the Vietnam War, the vastly out numbered 18th Division stood and fought at Xuan Loc, 38 miles north of Saigon. This battle is considered the epic last stand of ARVN forces, where the 18th earned the name "The Supermen". It was commanded by General Le Minh Dao, a smart, conservative and emotional commander. The 18th made a defiant apocalyptic last standagainst communist forces in Xuan Loc, a city strategically important for intersecting five main routes. The fierce fighting raged for two weeks. The 18th Division, outnumbered 7:1 by the Vietnam People's Army (VPA) forces, all but destroyed three VPA divisions before finally was overwhelmed by superior numbers. The division was forced to evacuate from the city on April 21, 1975, nine days before thefall of Saigon. Upon learning the 18th had lost "Xuan Loc" that afternoon at 3:00pm President Nguyen Van Thieu made a tearful televised speech that was broadcast around the world in which he blamed the United States for abandoning South Vietnam; he closed the speech by resigning the presidency. The 18th was finally destroyed while defending Bien Hoa Air Base.
There's also stories of airmen that fought until the end. The majority of Air Force planes stripped their planes of armaments and deserted to Thailand or American carriers, but some took off with a full payload and attacked the enemy until they were shot down.
This is a picture of two soldiers from the 18th.
I think what's more amazing about the 18th that they had that reputation for being mavericks. It goes to show you that no matter what other people think of you, if you know you're right, just do what you do. There's always an opportunity for redemption. You'll get your respect and your actions will echo in eternity.
Rest easy brothers, you're free now.
