The first train arrived in Bismarck June 5, 1873. Part of its cargo consisted of printing presses for the Bismarck _Tribune_, which was first issued July 11, 1873, and continues publication as North Dakota's oldest newspaper. The _Tribune's_ greatest scoop was scored in 1876 when it gave the world the story of the Custer massacre at the Little Big Horn in Montana. Mark Kellogg, reporter for the _Tribune_ and New York _Herald_, was killed in the battle, but more than a column of notes on the battle was found in a buckskin pouch on his body. When Grant Marsh's steamer _Far West_ brought Reno's wounded and the first news of the disaster, Col. C. A. Lounsberry, founder-editor of the _Tribune_, obtained the story, wiring it to the _Herald_ at a reputed cost of $3,000 for 24 hours use of the telegraph wires. Bismarck felt the loss of Custer's command keenly, for he and his Seventh Cavalry officers from Fort Abraham Lincoln had figured prominently in the social life of the city. The Bismarck _Sun_, another early newspaper, had a prominent part in the exposure of Indian and military post corruption which led to the impeachment of Secretary of War William W. Belknap in 1876. James A. Emmons, publisher of the paper, issued a handbill entitled _Pirates of the Missouri_ which alleged that appointments as traders at military and Indian posts were being bought from the Secretary of War. The New York _Herald_ sent out a reporter, who obtained a position at Fort Berthold Indian Agency, incognito, and succeeded in exposing the dishonesty prevalent at almost all of the Missouri River posts. The reporter barely escaped with his life when his identity was discovered; but he returned the next year and succeeded in completing his investigation. Belknap was impeached on a charge of bribery, and resigned, but was later acquitted. The episode caused a great furore throughout the country, but particularly in Bismarck. Gold was discovered in the Black Hills in 1874, and Bismarck experienced its first boom. A regular stagecoach and freight line was maintained to Deadwood, S. Dak. It was more than 200 air line miles cross country, with no towns between. Stations were established every 20 miles and all freight was hauled into the Black Hills by wagon, 10 or 12 yoke of "wild Montana cattle" being used to pull trains of two or three wagonloads of freight. Gold seekers flocked to Bismarck, where they outfitted their supply trains before departing for the gold fields. The Bismarck _Tribune_ of October 25, 1879, reported: "There are no rooms available at the hotels in Bismarck tonight as there are many transients in town bound for the Hills. Our freight and passenger business to the gold fields has been very heavy during the past ten days, amounting to 300,000 pounds of freight and seventy passengers. There were also two carloads of horses shipped in for the stage coaches. There are at present two and sometimes three stages a day."
