Dakota 38 Mankato mass execution

In the aftermath of the Dakota War of 1862, the US Military held trials for ~400 Dakota people involved in the war. Some trials lasted less than five minutes, the Dakota were given no defense representation, and the proceedings were not explained to them. The military commission called for 303 men to be sentenced to death. After review, president Abraham Lincoln ordered the hanging of 38 Dakota men which remains the largest single-day mass execution in American history. The grave was reopened the same night and all the bodies stolen and distributed to doctors- including the remains of Marpiya te najin, to William Mayo of the Mayo Clinic. The bodies were kept and not returned by Mayo Clinic until forced by NAGPRA in 1998. Additionally, two more men (Ṡaḳpedaƞ and Wakanozanzan) who escaped to the Red River Colony were drugged and brought back and hanged.
