Two or three nights after they arrived at the Fort, taking advantage of a dark evening, the Indians deprived them of all their animals. This was the result of carelessness on the part of one of the men, which, under the circumstances, was excusable. The party had encamped just without the pickets of the Fort, but had taken the precaution to secure their horses and mules while they slept, by placing them in the _corral_[12] belonging to the station. A sentinel was put upon duty over the corral, in order to make everything doubly secure. In the latter part of the night, nearly at daybreak, the sentinel saw two persons advance and deliberately let down the bars leading into the yard and drive out the animals. He mistook these men for two of his companions who were authorized to take the herd out to graze. Concluding, therefore, without going to them, that he was relieved, he sought his resting-place and was soon fast asleep. In the morning, anxious inquiries were made for the horses and mules, when a very short investigation revealed the truth of matters. It was, undoubtedly, very fortunate for the sentinel that he fell into the error alluded to. It was very apparent that the two advanced Indians who let down the bars were backed up by a strong party. The signs of Indians, discovered afterwards, proved this beyond a doubt. Their reserve party were posted where the least resistance on the part of the sentinel would have been followed by his quick and certain death. This successful theft was, no doubt, considered by the Indians a cause for great rejoicing. It may have formed the basis of promoting the brave who planned and directed it, as the animals had been obtained without the loss of a man or even the receiving of a wound. The parties living at the Fort were equally as poorly off for horses and mules as were now the trappers. The same Indians had recently performed the same trick upon them. The loss was most severely felt by the trappers, inasmuch as they had not a single animal left upon which to give chase. Nothing remained for them to enact, except a stoical indifference over their loss and await the return of McCoy, who had agreed, after finishing his business at Fort Walla Walla, to rejoin, them at Fort Hall.
