Before he arrived at Fort Rice, he was informed that Capt. James L. Fisk, with a party of immigrants, was in danger. Fisk, who had made expeditions through North Dakota in 1862 and 1863, on this trip followed Sully's trail, and in the Badlands was attacked September 1 by Indians, with the loss of several men. During the next few days several other attacks were made, although no one was killed. Messengers were sent to Sully for aid, and meanwhile the party threw up what fortifications they could in the form of sod walls, and, awaited help. After several days the soldiers arrived and brought the immigrants back to Fort Rice, whence most of them returned to their homes. The remains of their impromptu fortification, known as Fort Dilts, can still be seen (_see Tour 9_). One of the most valuable expeditions made through this State was the Stevens Survey of 1853, sent out to discover the most advantageous routes to the Pacific for future railroads. The party was financed by a Federal appropriation, and the northern route, through present North Dakota, was under the direction of Gen. I. I. Stevens. The guide on this expedition was Pierre Bottineau, one of the outstanding personalities in the history of North Dakota and Minnesota during this period. Of him it has been written that "It was the guide Bottineau who walked from Winnipeg to St. Paul with James J. Hill, it was the scout Bottineau who headed Jay Cooke's first Northern Pacific survey across the continent, it was the chief Bottineau who gave his name to Bottineau County, and it was the gambler Bottineau who had three queens in his hand, staked Nicollet Island, and lost." In 1871 the Whistler expedition went up the Little Missouri and into Montana in search of the most practical route for a railroad to the Pacific. Two years later the Stanley expedition, accompanied by a large military escort, conducted another western survey. Engagements with Indians cost this expedition a number of men. One Sioux, Rain-in-the-Face, claimed to have had a part in killing two civilians on the Stanley Survey, and as a result was imprisoned at Fort Lincoln until he escaped. He gained his revenge at the Little Big Horn (_see Side Tour 8C_). The Northern Pacific Railway received its charter from the Government in 1864. Magnificent Federal land grants were made: still the road found it difficult to raise the necessary capital to finance the venture, and Jay Cooke & Company undertook the sale of Northern Pacific securities. On the last day of the year 1871 the line was completed to the Red River at Moorhead, and early in March of the next year it was extended to Fargo. Cooke went into bankruptcy after the financial panic of 1873, but was able to obtain private funds to complete the road to the Missouri that year. Bismarck remained the western terminus of the line until 1879. During the next two years rails were laid to the Montana border, completing the line across the entire State.
