The soldiers stationed at the fort led a varied life, the monotony of frontier existence being tempered by fighting the Sioux, maintaining order among the lawless element which followed the progress of the railroad, and even building smudges to protect the workers from the tormenting swarms of bloodthirsty mosquitoes.

The three blockhouses and the palisade have been restored, so that the fort looks much as it must have looked more than 50 years ago when it crowned this bluff, guarding its prominent position on the river. None of the buildings within the enclosure is left, but the sites of all are marked.

To avoid confusion, the restored fort is commonly referred to as Fort McKeen, distinguishing it from the later Fort Abraham Lincoln, although the latter included both posts. The FORT ABRAHAM LINCOLN SITE is right of the park road just south of the Indian village. Markers indicate the sites of the various structures, and holes partly filled with debris also show where the buildings of the Northwest's strongest fortress once stood. A row of cottonwoods, which grew along Officers' Row, stands in lonesome splendor.

When Gen. George A. Custer and his spirited Seventh Cavalry came to Fort Abraham Lincoln in 1873 it became a nine-company cavalry and infantry post, with the cavalry established on the level plain below, where a good drill and parade ground was available. Custer, with his long sandy-colored hair and restless vivacity, was one of the most personable and interesting military men of his time. He and his wife, a young and talented woman, soon drew about themselves a social circle that was widely known and aspired to. Balls, musicales, and other entertainments drew people from the surrounding territory, including the new town of Bismarck across the river. The social life at Fort Abraham Lincoln would have been a credit to any city, as, beneath crystal chandeliers, to the music of the Seventh's band, stately couples moved in the graceful figures of the dance.

For the soldiers, life consisted chiefly of maintaining order among the Indians and the incoming white population. At one time the guardhouse at the fort had a distinguished occupant, Rain-in-the-Face, the Sioux warrior. He had been heard boasting of "counting coup" on the bodies of two white men killed on the Stanley expedition in 1873, and Tom Custer, brother of General Custer, was sent to take him into custody at Standing Rock Agency (see Side Tour 8C). Rain-in-the-Face was arrested and imprisoned at Fort Abraham Lincoln, but escaped in a jailbreak engineered by friends of some of the other prisoners, and joined Sitting Bull.

Life at the post often grew monotonous for the troopers, who in winter found their activities hampered by the severe cold, and in the summer suffered from the torments of the heat and the mosquitoes.

When the routine of military life palled too greatly on the soldiers, they took refuge in the activities of the Point, a little settlement of dance halls, saloons, and similar places of entertainment, that flourished on the opposite bank of the river directly across from the fort. Since there was no bridge across the Missouri the Point could be reached only by ferry or on the ice. At the time of the spring break-up, however, even the ferry could not be used, and many of the soldiers missed the customary recreational and liquid facilities afforded by the Point. One spring, as the ice was going out, a young man, whose fine physique was equalled only by his foolhardy daring, offered to cross the river for some liquor. Crossing a river on breaking ice has been known as a daring feat since even before the days of Eliza and the bloodhounds, but crossing the Missouri is a particularly hazardous exploit, for this river, always maliciously menacing, is even more so in the spring, with great ice blocks eddying and whirling, crunching violently together, then flung apart by the swift current. The slightest misstep or miscalculation meant death to the young, thirsty soldier, but with the greatest nonchalance he made the crossing and the return, bringing his precious burden back with him, and great and twofold was the rejoicing when he safely reached the home shore.

Three years of existence left Fort Abraham Lincoln in comparative quiet, with only an occasional Indian skirmish. Then events on the frontier conspired to bring the Indian troubles to an end. The campaign of the Little Big Horn was planned (see History). One day in 1876 the Seventh, with bands playing and colors flying, marched away along the Heart in pursuit of the Sioux. On a stifling night early in July the residents of Bismarck were awakened from their sleep by loud sounds of shouting, of wagons and horses moving, at the river. Capt. Grant Marsh had arrived from the Little Big Horn with his steamer, the Far West, loaded with the wounded of Major Reno's command, survivors of the Battle of the Little Big Horn. But more than the wounded, he bore news—news of the death of 267 men, of the annihilation of Custer and his immediate command. Twenty-six of the waiting wives at Fort Abraham Lincoln were widows.
