This left the three remaining officers practically as hostages in the Indian camp. Speaking of this incident. General Wood says: "Instead of taking advantage of our position, they assured us that while we were in their camp it was our camp, and that as we had never lied to them they were going to keep faith with us. They gave us the best they had to eat and treated us as well as we could wish in every way. Just before giving us these assurances, Geronimo came to me and asked to see my rifle. It was a Hotchkiss and he had never seen its mechanism. When he asked me for the gun and some ammunition, I must confess I felt a little nervous, for I thought it might be a device to get hold of one of our weapons. I made no objection, however, but let him have it, showed him how to use it, and he fired at a mark, just missing one of his own men, which he regarded as a great joke, rolling on the {45} ground, laughing heartily and saying 'good gun.' "Late the next afternoon we came up with our command, and we then proceeded toward the boundary line. The Indians were very watchful, and when we came near any of our troops we found the Indians were always aware of their presence before we knew of it ourselves." For eleven days Captain Lawton's command moved north, with Geronimo's and Natchez's camps moving in a parallel course. During these last days of Geronimo's leadership his greatest concern was for the welfare of his people. The most urgent request that he had to make of Captain Lawton was to ask repeatedly for the assurance that his people would not be murdered. Captain Lawton in his official report says of Wood's work in the campaign: "No officer of infantry having been sent with the detachment ... Assistant Surgeon Wood was, at his own request, given command of the infantry. The work during June having been done by the cavalry, they were too much exhausted to be used again without rest, and they were left in camp at Oposura to recuperate. {46} "During this short campaign, the suffering was intense. The country was indescribably rough and the weather swelteringly hot, with heavy rains for day or night. The endurance of the men was tried to the utmost limit. Disabilities resulting from excessive fatigue reduced the infantry to fourteen men, and as they were worn out and without shoes when the new supplies reached me July 29th, they were returned to the supply camp for rest, and the cavalry under Lieutenant A. L. Smith, who had just joined his troop, continued the campaign. Heavy rains having set in, the trail of the hostiles, who were all on foot, was entirely obliterated.
