Roys Oatman assumed command of the party. They reached New Mexico Territory early in 1851 only to find the country and climate wholly unsuited to their purpose. The other wagons gradually abandoned the goal of reaching the mouth of the Colorado River. The party had reached Maricopa Wells, when they were told that not only was the stretch of trail ahead barren and dangerous, but that the Native Americans ahead were very hostile and that they would risk their lives if they proceeded further. The other families resolved to stay. The Oatman family, eventually traveling alone, was nearly annihilated in what became known as the "Oatman Massacre" on the banks of the Gila River about east of Yuma, in what is now Arizona. Oatman massacre Mary Ann and Roys Oatman had seven children, and Mary Ann was pregnant with their eighth during their journey from Illinois to the Gila River. The Oatman children ranged in age from one to 17, the eldest being Lucy Oatman. On the Oatmans' fourth day out from Maricopa Wells, they were approached by a group of Native Americans who were asking for tobacco and food. Due to the lack of supplies, Royce Oatman was hesitant to share too much with the small party of Yavapais. They became irate at his stinginess. During the encounter, the Yavapais attacked the Oatman family. The Yavapais clubbed the family to death. All were killed except for three of the children: 15-year-old Lorenzo, who was left for dead, and 14-year-old Olive and 7-year-old Mary Ann, who were taken to be slaves for the Yavapais. After the attack, Lorenzo awoke to find his parents and siblings dead, but he saw no sign of little Mary Ann or Olive. Lorenzo attempted the hazardous trek to find help. He eventually reached a settlement, where his wounds were treated. Lorenzo rejoined the emigrant train, and three days later returned to the bodies of his slain family. In a detailed retelling which was reprinted in newspapers over the decades, he said, "We buried the bodies of father, mother and babe in one common grave." The men had no way of digging proper graves in the volcanic rocky soil, so they gathered the bodies together and formed a cairn over them. It has been said the remains were reburied several times and finally moved to the river for re-interment by early Arizona colonizer Charles Poston. Lorenzo
