The Battle of Pine Creek, also known as the Battle of Tohotonimme and the Steptoe Disaster, was a conflict between United States Army forces under Brevet Lieutenant Colonel Edward Steptoe and members of the Coeur d'Alene, Palouse and Spokane Native American tribes. It took place on May 17, 1858, near what is present-day Rosalia, Washington. The Native Americans were victorious.
Tension had been growing on the Columbia Plateau since the 1855 Walla Walla Council forced tribes to cede vast portions of land. Yakama chief Kamiakin opposed the treaties, and so did many leaders of the Nez Perce, Cayuse, and Walla Walla nations. Adding to the tension, some miners intruded on tribal lands and there were isolated attacks on Indians. Some tribes retaliated with isolated killings of whites. In late 1855, the Oregon militia mounted an attack resulting in the Battle of Walla Walla and the killing of Walla Walla chief Peopeomoxmox. Rumors that Lieutenant John Mullan would build a military road across their land fueled the outrage of tribes in the region. Finally, in 1858, Palouse people killed two miners as an act of vengeance for conflicts with tribal members. Fearing further violence, whites living at nearby Fort Colvile petitioned Steptoe for military protection.
Steptoe departed Fort Walla Walla on May 6, 1858. His stated mission was to investigate the murder of the two prospectors and to demonstrate a military presence in order to calm the white settlers. Steptoe also wanted to recover a herd of cattle that a group of Palouses had driven from Fort Walla Walla. Leaving the fort, Steptoe's command of 159 soldiers were each issued about 40 rounds of ammunition. The group also ported two mountain howitzers. Steptoe crossed the Snake River and entered the territory of the Spokane nation, contrary to the promise of Governor Isaac Stevens that whites would respect Spokane land as long as the tribe agreed to remain peaceful.
On May 15, Steptoe made camp on a hilltop south of Rosalia, Washington, in the territory of the Coeur d'Alenes. The next day, a party of tribal leaders confronted Steptoe and demanded an explanation for his incursion. Steptoe told them that he sought a resolution to tensions between miners and the tribes near Fort Colvile. He asked for help to cross the Spokane River, which was running high with spring snow melt. The tribes refused.
On the morning of May 17, Steptoe decided to turn back. He led his troops near the confluence of Spring Valley Creek and North Pine Creek. It was at this time a group of Coeur d'Alenes, joined by some Palouses, attacked. A running battle ensued for the next ten hours. More warriors joined the battle, and soon Steptoe found himself under attack by more than a thousand Palouse, Spokane, and Coeur d'Alene people. By early afternoon, Steptoe found himself defending against the attackers from a hill overlooking Pine Creek from the east. The Indian warriors withdrew for the night, expecting to finish the battle the next morning. They did not know that Steptoe's forces were down to about three rounds of ammunition per man. Under cover of darkness and a driving rain, Steptoe abandoned his supplies and cannon. He then led his command through enemy lines to safety toward Fort Walla Walla without being detected.
The early republic period saw the United States move from the weak Articles of Confederation to the federal Constitution ratified in 1788, with the Bill of Rights added in 1791. George Washington served two terms as president (1789–1797), establishing precedents for executive authority, and the federal capital moved permanently to Washington D.C. in 1800. The Louisiana Purchase (1803) doubled the nation's territory for roughly $15 million, opening vast trans-Mississippi lands to American expansion. The War of 1812 against Britain ended inconclusively but produced a surge of American national identity and eliminated most British support for Indigenous resistance east of the Mississippi. The Northwest Indian Wars (1785–1795) and the Creek War (1813–1814) broke Indigenous confederacies that had resisted US expansion. The Missouri Compromise of 1820 temporarily balanced slave and free states as the nation expanded westward, but embedded the contradiction of slavery in every subsequent territorial debate.
