After the TET offensive of 1968, the North Vietnamese Army forces fled back to their base camps in the jungle covered mountains where they lived, trained and prepared their attacks. During Operation Mameluke Thrust, Marines went into those mountains in search of the NVA. The Marines were hunting and the NVA were ready for them. During several battles, the NVA and Marines fought fiercely, with heavy casualties on both sides. This is the story of one of those battles told by a 19 year old Marine who fought in those battles. As the Marines swept along a river, the point platoon rappelled down a waterfall that then separated them from the main body of the Marine force. The NVA, who had been waiting in ambush, opened fire on both the point platoon and main body. The point platoon, isolated from the main body and in an open field surrounded by a numerically superior NVA force in fortified concealed positions, fought bravely. This story is dedicated to the 21 members of 3rd platoon of Bravo Company, 1st Battalion 7th Marines, who were killed or wounded at the waterfall in the mountains near Thuong Duc in Quang Nam province.
