First Battle of Seattle: Marines from the USS Decatur drive off American Indian attackers after all-day battle with settlers.

The Battle of Seattle was a January 26, 1856 attack by a coalition of Native American tribes upon Seattle, Washington. At the time, Seattle was a small, four-year-old settlement in the then-Washington Territory. It had recently named itself after Chief Seattle (Sealth), a leader of the Suquamish and Duwamish peoples of central Puget Sound. The settlement was already made the seat of King County in 1852.

USS Decatur was a sloop-of-war in the United States Navy during the mid-19th century. She was commissioned to protect American interests in the South Atlantic Ocean, including the interception of ships involved in the African slave trade. Decatur served in both the Mexican–American War and the American Civil War.

January 26 is the 26th day of the year in the Gregorian calendar; 339 days remain until the end of the year.
