Another Indian said: "Black Coyote is deaf," and when the soldier persisted, he said, "Stop. He cannot hear your orders." At that moment, two soldiers seized Black Coyote from behind, and (allegedly) in the struggle, his rifle discharged. At the same moment, Yellow Bird threw some dust into the air, and approximately five young Lakota men with concealed weapons threw aside their blankets and fired their rifles at Troop K of the 7th. After this initial exchange, the firing became indiscriminate. At first all firing was at close range; half the Indian men were killed or wounded before they had a chance to get off any shots. Some of the Indians grabbed rifles from the piles of confiscated weapons and opened fire on the soldiers. With no cover, and with many of the Indians unarmed, this lasted a few minutes at most. While the Indian warriors and soldiers were shooting at close range, other soldiers (from Battery E, 1st Artillery) used the Hotchkiss guns against the tipi camp full of women and children. It is believed that many of the soldiers were victims of friendly fire from their own Hotchkiss guns. The Indian women and children fled the camp, seeking shelter in a nearby ravine from the crossfire. The officers had lost all control of their men. Some of the soldiers fanned out and finished off the wounded. Others leaped onto their horses and pursued the Natives (men, women, and children), in some cases for miles across the prairies. In less than an hour, at least 150 Lakota had been killed and 50 wounded. Historian Dee Brown, in "Bury My Heart at Wounded Knee", mentions an estimate of 300 of the original 350 having been killed or wounded and that the soldiers loaded 51 survivors (4 men and 47 women and children) onto wagons and took them to the Pine Ridge Reservation. Army casualties numbered 25 dead and 39 wounded. On 30 December 1890, the day after Wounded Knee, COL Forsyth and 8 Troops of the 7th Cavalry and one platoon of Artillery (the same units that had been engaged at Wounded Knee), conducted a reconnaissance to see if the nearby Catholic Mission had been torched by the Indians. In what became known as the Drexel Mission Fight, the 7th Cavalry was ambushed in a valley by Brulé Lakota under Chief Two Strike from the Rosebud Indian Reservation. Struggling through the thick snow and pinned in the valley, the Troopers' situation was perilous.
