Lincoln and the main army continued southwards. Outside Doncaster, Lincoln encountered Lancastrian cavalry under Edward Woodville, Lord Scales. There followed three days of skirmishing through Sherwood Forest. Lincoln forced Scales back to Nottingham, where Scales' cavalry stayed to wait for the main royal army. However, the fighting had slowed down the Yorkist advance sufficiently to allow King Henry to receive substantial reinforcements under the command of Lord Strange by the time he joined Scales at Nottingham on 14 June. Rhys ap Thomas, Henry's leading supporter in Wales, also arrived with reinforcements.
