Following a few years of uneasy peace, the Yorkists' rebellion erupted once again, and John Neville fought alongside his father and elder brother Thomas at the Battle of Blore Heath in September 1459. Although the Earl of Salisbury fought off the Lancastrians, both his sons were captured, and John, with Thomas, spent the next year imprisoned. Following his release in 1460, he took part in the Yorkist government. His father and brother died in battle just after Christmas 1460, and in February the next year, John – now promoted to the peerage as Lord Montagu – and Warwick fought the Lancastrians again at St Albans. John was once again captured and not released until his cousin Edward, York's son, won a decisive victory at Towton in March 1461, and became King Edward IV.
