Late in the night, when the moon was in mid-heaven, he came to my tent, and told me that something was the matter with Vixen. My adjutant and I hastened out, and there we beheld her in the agony of a brain fever. She was the most painfully magnificent animal I ever saw. Crouched on the ground, with her forelegs stretched out and wide apart, she was swaying to and fro, with hard and stertorous breath,--every vein swollen and throbbing in the moonlight. De Grandèle, our quiet veterinary surgeon, had been called while it was yet time to apply the lancet. As the hot stream spurted from her neck she grew easier; her eye recovered its gentleness, and she laid her head against my breast with the old sigh, and seemed to know and to return all my love for her. I sat with her until the first gray of dawn, when she had grown quite calm, and then I left her with De Grandèle and Rudolf while I went to my duties. We must march at five o'clock, and poor Vixen could not be moved. The thought of leaving her was very bitter, but I feared it must be done, and I asked De Grandèle how he could best end her sufferings,--or was there still some hope? He shook his head mournfully, like a kind-hearted doctor as he was, and said that he feared not; but still, as I was so fond of her, if I would leave him six men, he would do his best to bring her on, and, if he could not, he would not leave her alive. I have had few harder duties than to march that morning. Four days after, De Grandèle sent a message to me at our station near Rolla, that he was coming on nicely, and hoped to be in at nightfall. "Vixen seems to be better and stronger." At nightfall they came, the poor old creature stepping slowly and timidly over the rough road, all the old fire and force gone out of her, and with only a feeble whinny as she saw me walking to meet her. We built for her the best quarters we could under the mountain-side, and spread her a soft bed of leaves. There was now hope that she would recover sufficiently to be sent to St. Louis to be nursed. That night, an infernal brute of a troop horse that had already killed Ludlow's charger, led by some fiendish spirit, broke into Vixen's enclosure, and with one kick laid open her hock joint. In vain they told me that she was incurable. I could not let her die now, when she was just restored to me; and I forced from De Grandèle the confession that she _might_ be slung up and so bound that the wound would heal, although the joint must be stiff. She could never carry me again, but she could be my pet; and I would send her home, and make her happy for many a long year yet. We moved camp two miles, to the edge of the town, and she followed, painfully and slowly, the injured limb dragging behind her; I could not give her up. She was picketed near my tent, and for some days grew no worse.
