The Battle of Pease River occurred on December 18, 1860, near the town of Margaret, Texas in Foard County, Texas, United States. The town is located between Crowell and Vernon within sight of the Medicine Mounds just outside present-day Quanah, Texas. A monument on that spot marks the site of the famous battle between the Comanche Indians under Peta Nocona and a detachment of Texas Rangers and militia under Ranger Captain "Sul" Ross. The battle was fought to protect the lives and property of white settlers in the area who had encroached on land historically belonging to the Comanches.
