I have a good friend who fought in the 1968 Vietnam Tet Offensive. He talks about how, in the battle's aftermath, he and his buddies patrolled the streets of Hue City, site of some of the most intensive fighting. He describes walking on the bodies of dead North Vietnamese and Viet Cong soldiers piled several layers high in the strategic provincial capital, and is also quick to remind me that Tet was a stunning military victory for the United States; that in fact, the US did not lose a single military encounter for the rest of the war.
