From The Warminster Official Guide And Souvenir 1928 (penned by Victor Strode Manley):
Stuart Times.
During the Civil War between Royalist and Roundhead, the town suffered from the enforced demands of both sides alternately, and several sharp skirmishes occurred. The army of James II mobilised near Cley Hill to meet Monmouth, and being prevented by nose-bleeding at Salisbury from reviewing it, he escaped assassination here.
