During the night Sir Simon Digby got into the royal camp as a spy, and returned with the report that the troops were in motion. The rebel leaders, therefore, sounded to arms. This must have been at dawn of Monday, August 22, 1485. The sun rose that {154} day at a quarter after five.[14] King Richard marched north-eastward for two miles to effect a junction with the Duke of Norfolk. The royal army was then formed in two lines, along the ridge of Sutton Fields. The archers were in the front line, with a few small pieces of artillery, under the Duke of Norfolk. The bill-men formed the rear line, and the horse were on the flanks. Stanley marched at the same time as the King, and halted to the rear of his left flank. The Earl of Northumberland arrived the same morning, but he seems to have thought that his men needed rest. He took no part in the battle. This slackness and want of zeal were punished in after years by the loyal people of Yorkshire.[15] King Richard was dressed in the same suit of polished steel that he had worn at Tewkesbury, with a golden circlet round his helmet. He rode to a knoll, since called 'Dickon's Nook,' and addressed the army in a spirit-stirring speech, calling on all true Englishmen to resist the foreign invaders, and appealing to their loyalty and patriotism. He then led them down the slope, placing his right towards Ambien Leys. In front of his centre there was a well, since known as King Richard's Well. Philibert de Shaundé had formed the insurgents across Redmore Plain, with a morass on their right flank. In their first line was John Vere in the centre, Sir Gilbert Talbot on the right, and Sir John Savage on the left wing. Jasper Tudor commanded the second line, and his nephew Henry kept well in {155} the rear. John Vere ordered his men not to advance more than ten paces in front of their standard; for he knew of the contemplated treachery, and that the royal troops would be attacked in the rear. As soon as the King saw that the insurgents had left their camp and advanced round the morass, he gave the order for the attack at about 10 A.M. A volley of arrows was discharged on either side: probably a few shots from some small pieces of ordnance were fired by the rebels.[16] Then the traitor Stanley threw off the mask and fell upon the left rear of the royal army, throwing it into confusion. The Duke of Norfolk fought gallantly and fell in the thickest of the battle.
