Edward IV flees to Burgundy, after the rebels under Earl of Warwick, who had by then sided with his former enemy Margaret of Anjou, invaded England with the help of French troops to restore Henry VI.  Edward was accompanied by his brother-in-law Anthony, Earl Rivers, and William Lord Hastings.  It seems his brother Richard (later Richard III) followed later after trying to gather to support for Edward in England.
