Philip Sheridan, a Union General instrumental in forcing Robert E. Lee’s surrender at Appomattox, gained fame in the Northwest during the 1850s by capturing 13 local Cascades Indians near present-day Stevenson. Colonel George Wright ordered nine of them hung — without a trial and despite evidence of outside responsibility for the deaths of 12 settlers. Sheridan, who served under Gabriel Rains during the Yakima Indian Wars, received military commendation. He served in the Northwest from 1854-1861, when called east to join the Civil War.
