Towton (Wars of the Roses).
Fought March 29, 1461, when Edward IV, immediately after his proclamation, marched against the Lancastrians, under Henry VI, and vigorously attacked their entrenched position at Towton. Aided by a heavy snowstorm, blowing in the faces of the defenders, Edward defeated them all along the line, with heavy loss, among the killed being Northumberland, Dacre and de Mauley. Henry and Margaret escaped from the field, and fled northward.
