Never before, and never since, has the valley of the Rosebud beheld such a gathering as was there to be seen on that brilliant 10th of August, 1876--brilliant, that is to say, as nature could make it, for in General Crook's command, at least, there was nothing of embellishment. The war of the Revolution, the huts of Valley Forge, never exhibited so sombre an array of soldiery as we presented when General Terry and his brigade confronted us at the great bend. It may be said that we were surprised at the meeting, and it can be established that they were astonished. Marching up the valley, General Terry was in daily expectation of finding a mass of Indians in his front. At latest accounts they were in strong force--in thousands, no doubt--between him and General Crook's position at the base of the Big Horn, and he commenced his aggressive move with every precaution, and with supplies for a long and stirring campaign. He had with him a complete wagon train, tents and equipage of every description. We had a few days' bacon and hard-tack, coffee and sugar, and a whole arsenal of ammunition on our mules, but not a tent, and only one blanket apiece. He had artillery in the shape of a few light field-pieces, and was making slow, cautious advances up the Rosebud at the rate of eight or ten miles a day. He had not come upon a single recent Indian "sign," yet knew that the country to the south must have been full of them within the fortnight. So when his scouts reported an immense cloud of dust coming down the valley above the bend, and his Indian allies began the same absurd gyrations and uproar which we had observed in ours, he very naturally supposed that a horde of hostiles was sweeping down to the attack, and made his dispositions accordingly. It was my good-fortune to be in our advance, and to witness the beautiful deployment of the Seventh Cavalry over the plains in our front, and it is hard to say which side would have whipped if we had not discovered that neither was Sioux. A report gained credence later in the day that Dr. Clements, Crook's medical director, said that it would be Sioux-icidal to fight under the circumstances; but his friends believed that this eruptiveness was due to professional disappointment at the non-employment of himself and his able assistants, and the matter was hushed up.
