Photograph of U.S. soldiers under fire (cropped). Associated Press caption reads: "A group of U.S. 1st Cavalry Division soldiers, several of them wounded, race through Viet Cong sniper fire to reach helicopter in a cemetery in Haoi Chau Jan. 31. Sand and air blasts from helicopter rotor whip at them as they dash through the cemetery, dodging gravestones and enemy fire. Troops of the unit which were not evacuated on helicopter were caught in a deadly crossfire when friendly South Vietnamese troops mistakenly opened fire on them from opposite side of enemy fire. This is one of a series by associated press photographer Eddie Adams."
