Maryland hired a ruffian named Thomas Cresap to force the issue. He and his armed followers moved up the Susquehanna River from Havre de Grace, Maryland to the 40th parallel settling on the west bank of the river. From there they began harassing their Pennsylvania neighbors. They killed livestock and tore down fences. In 1732 the hostilities quieted down when the two colonies reached an agreement. But Lord Baltimore went back on the agreement two years later. Cresap and his men resumed raiding farms and telling Pennsylvania Quakers that if they wanted it stopped they would pay the taxes they owed Maryland.
