The Cayuse War 1848-1855

After the Cayuse Indians killed 14 whites and held 53 others captive until ransomed [the Whitman Massacre], about 500 settlers took up arms and marched through Cayuse territory (southeast Washington and northeast Oregon), demanding the surrender of the warriors responsible for the crimes. US troops and militiamen from the Oregon territory were called in to suppress the Cayuse, who refused to make peace and raided settlements. Five captured Cayuse were tried and convicted of murder by a military commission and hanged on June 3, 1850. Bloodshed in the area continued until 1855, when the Indians were defeated and placed on a reservation with the Umatilla Indians. The Cayuse were greatly reduced in number by the war, and much of their tribal land was taken.

Armed Conflict Events Database

Armed Conflict Events Data (ACED) is an research project providing independent information about known wars, international disputes, civil wars, rebellions, coups, revolutions, genocides and other violent conflicts. ACED has been online since December 2000. Various partial revisions and modifications have been implemented since then, however, the limitations of the this format hamper further development. During 2005, the decision was made to radically restructure the available conflict information into a database. The new Armed Conflict Events Database (ACEDb) will substantially increase the utility of available conflict data for students of military history. As well, it will offer expanded opportunities to add and edit records of conflict. Existing research material will be maintained in its present form but no revisions are planned. More news about the development of ACEDb may be found at News About the Armed Conflict Events Database. Feedback is welcome.
