Fort Gibson was not only the oldest and most celebrated military establishment in the annals of Oklahoma but in its early days it was the farthest west outpost of the United States, and in many respects continued for years to be one of the most important on that frontier. It was one of the chain of forts reaching from the northern to the southern boundaries of the nation, which included Fort Snelling, Fort Leavenworth, Fort Gibson, Fort Towson, and Fort Jesup, at times there were as many soldiers stationed at Fort Gibson as in all the other forts together. It was constructed in a wilderness frequented by bears, wolves, and panthers, while the neighboring prairies were the feeding grounds of wild horses, buffalo and deer. The nearby streams were rich in beaver, and furs were shipped by trappers and traders to eastern markets.
