In June, regimental headquarters went to Fort Vancouver and the several companies were distributed through Oregon, Washington Territory, Idaho, California, Nevada and Arizona, no two being at the same station.

Although not defined by one large battle, this series of guerrilla skirmishes and frontier clashes across the high-desert sagebrush plains would be the deadliest Indian War in the West, with 1,762 fatalities.

[10][circular reference] These skirmishes included an expedition from Fort Bidwell, California, during 22–29 October 1866, when Company A killed 14 Indians, three women, four children, and captured an entire camp.

Lieutenant C. E. S. Wood, A. D. C., wrote: "The entire fight was closely watched by the general commanding, who desires to express his opinion that no troops ever behaved better or in a more soldierly manner than did the officers and men engaged in this encounter."

In June 1884, the regiment was transferred to the Department of Dakota, after a tour of nearly 30 years on the Pacific coast, during the greater part of which time its stations were remote from civilization and its duties of a most arduous and thankless character.

Conflict with the "Crows" came in the fall of 1887, and on the morning of 4 November, Colonel Dudley left Fort Custer with Troops A, B, D, E, G and K, and Company B, 3d Infantry, with a section of Hotchkiss guns, to arrest "Sword Bearer" and the Indians who had fired into the agency buildings on the night of 30 September.

[16][page needed] Meanwhile, to the east of the pass, C company ambushed and destroyed three enemy troop-carriers and captured a detachment of German motorcycle troops near the village of Chouigui.

C company made an immediate attack; advancing line abreast and firing on the grounded aircraft, the M3 tanks destroyed twenty enemy planes, and only two managed to escape.

To the north, enemy infantry was seen dismounting from a column of trucks, so the remaining tanks of A Co and B Co advanced on them and decimated this force, breaking down the farmhouse gates and eliminating its garrison.

Three Panzers broke into the battalion rear area, turned, and destroyed five M3 Stuarts and five M3 halftracks, forcing 1-1 Armor to withdraw, and opening a hole in the Allied line.

During their service in the Central Highlands, troopers saw action in Pleiku, Đắk Tô, Suoi Doi, Kon Tum, An Khê and many other nameless stretches of road and jungle.
