The conflict that occurred at wounded knee in 1890 can best be described as a) the first major battle in the united states civil war. b) a massacre of over 300 union soldiers by the sioux. c) the last major battle in the united states civil war. d) a massacre of over 300 sioux, including women and children.

The correct answer is option D.

After the Seventh Regiment Cavalry gathered and rounded up over 300 Sioux at Wounded Knee Fort, an attempt at disarming them led ultimately to the massacre of more than 300 Sioux. Also about 40 whites died during the incident.

A deaf American Indian, confused by the orders from the soldiers, refused to follow orders thus starting the incident which ultimately would cost the lives of over 350 people, both Sioux and whites.
