In a supposed retaliation for a Union raid on Osceola, Missouri, Lieutenant Colonel William C. Quantrill led a force of about 300 to 400 partisans in an attack on the city of Lawrence, Kansas.
His men killed civiliansmen and boysand destroyed many of the buildings.

The "Lawrence Massacre" was, perhaps, the extreme example of the vicious Kansas-Missouri border warfare.
