In spite of the fact that Geronimo had one of the very best farms in the entire San Carlos Reservation, the Apache leader soon was again in trouble with the United States in 1884, when attempts were made to stop the making and sale of tiswin. This was an Indian drink and highly intoxicating.

In 1884-5, Geronimo gathered and led a band of Apaches that not only terrorized the settlers in southern Arizona and New Mexico, but also the inhabitants of Sonora and Chihuahua in Mexico. General Crook was ordered to proceed against the raiders and to capture or kill the chief and his followers. The story of the war is filled with exciting deeds of daring, but through them all Geronimo looms as the foremost figure. His name came to inspire terror.

At last in March, 1886, a truce was made and this was followed by a conference, at which terms of surrender were agreed upon. But the wily Geronimo was not yet caught. Again with a band of his devoted followers he fled to the Sierra Madre mountains, beyond the borders of Mexico.

General Miles was now in command of the United States troops and quickly he began an energetic campaign against the Apache outlaws. This continued until August, when the war came to an end. The entire band of 340 were made prisoners and the warfare at last was ended. Geronimo and Nachi (the latter a hereditary chieftain of the tribe, though his comrade was the real leader), were sent as prisoners of war to Florida. Later they were removed to Alabama and at last were settled near Fort Sill, Oklahoma. There, Geronimo evidently concluded (and his conclusion was the more easily arrived at because he was under the continual supervision of United States soldiers) that he had had a sufficiency of war and that henceforth he was to be a man of peace. He became prosperous, and was a most cautious spender of his money.

The part which Lieutenant Pershing, a young officer fresh from West Point, had in the round-up of this campaign naturally was not of a character to bring him into great prominence. That he did his work well and that he had the full confidence of his men, however, are evidenced from the following incidents which remain among the reports of the campaign.

In the autumn maneuver in 1887, he was specially complimented by General Miles for "marching his troops with a pack train of 140 mules in 46 hours and bringing in every animal in good condition." Doubtless his early experiences in dealing with mules on a Missouri farm had stood him in good stead.

Another instance of his courage and his ability to deal with men, even at this early stage in his career, was shown when word came of the dire predicament of a score of "bad men"—horse thieves and cow-punchers—who had been surrounded by the Indians and were threatened with the death of every one in the band unless they should be speedily rescued. The young lieutenant with his detachment not only succeeded in penetrating to their refuge, but also in saving every one of them without the loss of the life of one man, white or red. The same qualities that had been displayed in his student days were here again in evidence. His sense of duty was still strong upon him and quietly, persistently, he worked hard to do his best.

There still was work for the lieutenant on the border, for the troubles with the Indian tribes were by no means ended. His service on frontier duty at Fort Bayard, New Mexico, and in the field from July 30, 1886, to July 30, 1887, was followed by duty at Fort Stanton, New Mexico.

He went to Fort Wingate, New Mexico, in February, 1889, remaining there until September 1, 1889. He then returned to Fort Stanton to stay until September, 1890, when again he was sent to Fort Wingate.

At Fort Wingate, with the exception of a few weeks spent in scout duty, he remained until December 1, 1890, when he was transferred to take the field in the campaign against the Sioux Indians at Pine Ridge Agency, South Dakota. In February, 1891, he was stationed at Fort Niobrara, in Nebraska, only to return to the Pine Ridge Agency to take command of the Sioux Indian Scouts until July of the same year. Again he was with his troops at Fort Niobrara, remaining until August 7, 1891, when he was in command of a detachment (rifle team) en route to Fort Sheridan, Illinois. On September 25th he became Professor of Military Science and Tactics at the University of Nebraska at Lincoln, Nebraska.
