"Map Exhibiting the Lines of March Passed Over by the Troops of the United States During the Year Ending June 30th 1858...", U.S. War Department

This finely engraved map shows Army troop movements throughout the United States by land and sea in the preceding year. It includes topography, hydrography, forts, towns, and international boundaries. With an average effective force of about 10,000 men, the Army was hard pressed to provide adequate security to its citizens, particularly in the frontiers of Texas, Arkansas, Arizona, and Minnesota. Thus it was necessary to constantly withdraw forces from one frontier to reinforce another. This map clearly shows the enormous logistics problem that faced the Army in its efforts to maintain a suitable force to contain the hostile Indians.
