Dark Sunrise Vietnam removes readers from the easy chair and places them with two Marine Corps Divisions in Vietnam. The South Vietnamese cannot defeat the Viet Cong or North Vietnamese in combat. Before long the Marine Corps 3rd Division is sent north to the DMZ. The 1st Marine Division South to Da Nang and the Mekong Delta. The Marines have a bond between them forged in steel and tempered in blood. Search and Destroy missions, Combat sweeps and Patrols are conducted. A continuous problem is surrounding the enemy in combat and suddenly intense silence. Combat sweep of the area reveals no enemy dead, where did they go? The enemy is almost always invisible unless willing to be seen. The Ho Chi Minh trail is found with elephants carrying heavy guns or ammunition. Also thousands of old men and women moving supplies on their backs or bicycles. When the tunnels of Chu Chi are discovered, they weave through a trail of deception, Bear traps, Punji traps, snares, trip wires, tiger pits, bombs, lures, shadows and ambush. Help from the Mongtagnard Tribesmen is requested. How does this all end?
