She next de- feated Warwick at the second battle of St. Albans; but being routed at Towton, she fled to France to implore succor from Louis XL, who refused her any assist- ance. This intrepid woman then returned to England, where she was joined by sev- eral of her party, but was defeated at Hexham.
