"As soon as it was dark on the evening of the second, I proceeded with my command from Fort Henrietta to Walla Walla, having left a detachment of twenty-five men, under command of Lieutenant Sword, to protect the former post. On the morning of the third we encamped on the bank of the Walla Walla River about four miles from the fort; and, proceeding to the latter place, I found it had been pillaged by the Indians, the buildings much defaced and the furniture destroyed.
"On the morning of the fourth, a body of Indians was observed on the opposite side of the Columbia, apparently making preparations to cross the river with a large amount of baggage. Seeing us in possession of the fort, they were deterred from making the attempt, when I sent a small detachment down to a bar making into the Columbia immediately below the mouth of the Walla Walla, and opposite to where the Indians were, with directions to fire upon them and prevent the removal of their packs of provisions. The width of the river at this place is about 250 yards; and a brisk fire was at once opened upon the Indians, which was returned by them from behind the rocks on the opposite shore. No boats could be procured to cross the river in order to secure the provisions or to attack the body of Indians, numbering about fifty, who had made their appearance on the hill north of Walla Walla, who, after surveying our encampment, started off in a northeasterly direction. I at once determined to follow in pursuit of them on the following day.
"Early on the morning of the fifth I dispatched Second Major Chinn, with 150 men, to escort the baggage and packtrains to the mouth of the Touchet, there to await my return with the remainder of the forces under my command. On the same morning I marched with about two hundred men to a point on the Touchet River about twelve miles from its mouth, with the view of attacking the Walla Walla Indians, who were supposed to be encamped there. When I was near to and making towards the village, Peupeumoxmox, the chief of the tribe, with six other Indians, made their appearance under a flag of truce. He stated that he did not wish to fight; that his people did not wish to fight; and that on the following day he would come and have a talk and make a treaty of peace. On consultation with Hon. Nathan Olney, Indian agent, we concluded that this was simply a ruse to gain time for removing his village and preparing for battle. I stated to him that we had come to chastise him for the wrongs he had done to our people, and that we would not defer making an attack on his people unless he and his five followers would consent to accompany and remain with us until all difficulties were settled. I told him that he might go away under his flag of truce if he chose; but, if he did so, we would forthwith attack his village. The alternative was distinctly made known to him; and, to save his people, he chose to remain with us as a hostage for the fulfillment of his promise, as did also those who accompanied him. He at the same time said that on the following day he would accompany us to his village; that he would then assemble his people and make them deliver up all their arms and ammunition, restore the property which had been taken from the white settlers, or pay the full value of that which could not be restored; and that he would furnish fresh horses to remount my command, and cattle to supply them with provisions, to enable us to wage war against other hostile tribes who were leagued with him. Having made these promises, we refrained from making the attack, thinking we had him in our power, and that on the next day his promises would be fulfilled. I also permitted him to send one of the men who accompanied him to his village to apprise the tribes of the terms of the expected treaty, so that they might be prepared to fulfill it.
"On the sixth, we marched to the village and found it entirely deserted, but saw the Indians in considerable force on the distant hills, and watching our movements. I sent out a messenger to induce them to come in, but could not do so. And I will here observe that I have since learned from a Nez Percé boy who was taken at the same time with Peupeumoxmox, that instead of sending word to his people to make a treaty of peace, he sent an order for them to remove their women and children and prepare for battle. From all I have since learned, I am well persuaded that he was acting with duplicity, and that he expected to entrap my command in the deep ravine in which his camp was situated, and make his escape from us. We remained at the deserted village until about one o'clock in the afternoon; and seeing no hope of coming to any terms we proceeded to the mouth of the Touchet with a view of going from thence to some spot near Whitman's Station, where I had intended to form a permanent camp for the winter.
"On the morning of the seventh, Companies H and K crossed the Touchet, leading the column on the route to Whitman's Valley, and when formed on the plain, were joined by Company B. A few persons in front were driving our cattle; and a few were on the flanks of the companies and near the foot of the hills that extended along the river. These persons, as well as I can ascertain, were fired on by the Indians. Immediately all the companies except A and F (who were ordered to remain with the baggage) commenced an eager chase of the Indians in sight. A running fight was the consequence, the force of the Indians increasing with every mile. Several of the enemy were killed in the chase before reaching the farm of La Rocque, which is about twelve miles from the mouth of the Touchet. At this point they made a stand, their left resting on the river covered with trees and underbrush, their center occupying the flat, as this place was covered with clumps of sagebrush and small sand knolls, their right on the high ridge of hills which skirt the river bottom.
FORT WALLA WALLA
"When the volunteers reached this point, they were not more than forty or fifty men, being those mounted on the fleetest horses. Upon these the Indians poured a murderous fire from the brushwood and willows along the river, and from the sage bushes along the plain, wounding a number of the volunteers. The men fell back. The moment was critical. They were commanded to cross the fence which surrounds La Rocque's field, and charge upon the Indians in the brush. In executing this order, Lieutenant Burrows of Company H was killed; and Captain Munson of Company I, Isaac Miller, sergeant-major, and G. W. Smith of Company B, were wounded. A dispatch having been sent to Captain Wilson of Company A to come forward, he and his company came up on the gallop, dismounted at a slough, and with fixed bayonets pushed on through the brush. In the course of half an hour Captain Bennett was on the ground with Company F; and, with this accession, the enemy was steadily driven forward for two miles, when they took possession of a farm house and close fence, in attempting to carry which Captain Bennett of Company F and Private Kelso of Company A were killed.
"A howitzer found at Fort Walla Walla under charge of Captain Wilson, by this time was brought to bear upon the enemy. Four rounds were fired, when the piece bursted, wounding Captain Wilson. The Indians then gave way at all points; and the house and fence were seized and held by the volunteers and the bodies of our men recovered. These positions were held by as until nightfall, when the volunteers fell slowly back and returned unmolested to camp.
