During the Civil War, Phillips Farm suffered. Quaker Thomas Phillips was a pacifist, but troops from both sides helped themselves to his horses and crops. A sister lamented, “. . . it is really too bad for him to be treated so.” In October 1862, after the Battle of Antietam, a Federal infantry division paused at Waterford for several days on its way south. Soldiers camped here and on nearby farms. In July 1863, after Gettysburg, thousands of Union troops poured into Waterford; many set up camps along Catoctin Creek. Quakers offered “grass for thy horses, a fine spring for thy men and beasts, and ricks of cordwood for thy cooking.” But the following year Federal troops burned the Phillips barn.
