14. friendly fire kills both sides: eyewitness phillip wells

key words, sioux, 7th cavalry: December 29, 1890; .. murder of 297 Sioux Indians at Wounded Knee These 297 people, in their winter camp, were murdered by federal agents and members of the 7th Cavalry who had come to confiscate their firearms "for their own safety and protection". The slaughter began AFTER the majority of the Sioux had peacefully turned in their firearms.
at wounded knee, 1890: The 7th Cavalry troopers, most of them young and unseasoned, clenched their jaws... Custer’s fatal drive to the Little Bighorn was only 14 years in their regiment’s past.

The Battle of the Little Bighorn,.. commonly referred to as Custer's Last Stand, was an armed engagement between combined forces of the Lakota {sioux}, Northern Cheyenne, and Arapaho tribes and the 7th Cavalry Regiment of the United States Army. The battle, which occurred June 25–26, 1876, near the Little Bighorn River in eastern Montana Territory, was the most prominent action of the Great Sioux War of 1876.

greydee Thos: One big point is: Unarmed people do not fight back

Not true, unarmed people often do fight back, tho they tend to suffer more severe casualties. What maybe you meant to say is Armed people sometimes do not fight back, when they are outnumbered or demoralized.

.. the sound of a shot pierced the early morning gloom. Within seconds the charged atmosphere erupted as Indian braves scurried to retrieve their discarded rifles and troopers fired volley after volley into the Sioux camp. From the heights above, the army's Hotchkiss guns raked the Indian teepees with {cannon} grapeshot.

seemingly a better source for wounded knee than the rightwing crap you cited: Eyewitness to a Massacre Philip Wells was a mixed-blood Sioux who served as an interpreter for the Army. He later recounted what he saw that Monday morning:
"I was interpreting for {colonel} Forsyth just before the battle of Wounded Knee, December 29, 1890. The captured Indians had been ordered to give up their arms, but Big Foot replied that his people had no arms. Forsyth said to me, 'Tell Big Foot he says the Indians have no arms, yet yesterday they were well armed when they surrendered. He is deceiving me. Tell him he need have no fear in giving up his arms, as I wish to treat him kindly.' Big Foot replied, 'They have no guns, except such as you have found.' Forsyth declared, 'You are lying to me in return for my kindness.'
During this time a medicine man, gaudily dressed and fantastically painted, executed the maneuvers of the ghost dance,.. Turning to the young warriors who were squatted together, he said 'Do not fear, but let your hearts be strong. Many soldiers are about us and have many bullets, but I am assured their bullets cannot penetrate us. The prairie is large, and their bullets will fly over the prairies and will not come toward us. If they do come toward us, they will float away like dust in the air.'
{soldier said} 'Tell the Indians it is necessary that they be searched one at a time.' The young warriors paid no attention to what I told them. I heard someone on my left exclaim, 'Look out! Look out!' I saw five or six young warriors cast off their blankets and pull guns out from under them and brandish them in the air. One of the warriors shot into the soldiers, who were ordered to fire into the Indians.
Troop 'K' was drawn up between the tents of the women and children and the main body of the Indians, who had been summoned to deliver their arms. The Indians began firing into 'Troop K' to gain the canyon of Wounded Knee creek. In doing so they exposed their women and children to their own fire.

Around 40 members of the 7th Cavalry were killed, over half cut down by friendly fire from the Hotchkiss guns of their overzealous comrades-in-arms. Twenty members of the 7th Cavalry were deemed "National Heros" and awarded the Medal of Honor for their acts of cowardice.

another source: Yet getting warriors to surrender their guns was a touchy business.. as Forsyth and an ailing Big Foot parleyed in the center of the camp on Wounded Knee Creek, using the 40-year-old Wells as their go-between, a medicine man whirled and dipped, threw handfuls of dust into the air and urged the Minneconjous to believe what the Ghost Dance taught... Men leaped to their feet. Younger warriors were throwing off their blankets, bringing their rifles to their shoulders. One brandished his rifle in the air, vowing to keep his gun forever. Another fired into the soldiers. Officers screamed at their men to return fire. The camp exploded in a tumult of gunfire and smoke. http://www.historynet.com/philip-wells-wounded-at-wounded-knee.htm
