The King only had one full day in London, in which to organise his little army, now increased to 9,000 men, and to rest the faithful few who had marched with him from Ravenspur. He entered London on the 11th, and in the forenoon of the 13th he marched out to encounter his enemies. Advancing to Barnet his scouts drove out the scouts of Warwick and chased them for half a mile. The King then marched through the town, and reached Gladmore Heath when it was dusk. He encamped much nearer the enemy than he intended, and by reason of the darkness his line was not formed directly in front of the opposing force. {49} The King's right extended beyond Warwick's left, while his left was similarly overlapped by Warwick's right. In one respect this was fortunate, for Warwick's artillery was in his right wing, and he kept up a fire all through the night[11] without doing any damage to his adversaries, because their left wing was not posted in front of the rebel right wing; but somewhat to the eastward of it. Warwick had drawn up his army with his brother Montagu and John Vere, son of the attainted Earl of Oxford, in charge of the right wing consisting mainly of cavalry; the Duke of Somerset in the centre with archers and bill-men; and Warwick himself, with the Duke of Exeter, in command of the left wing. The opposing force of the King was inferior in numbers to that of the rebels. Edward, accompanied by Clarence and Henry VI., commanded the centre in person. On the left was Lord Hastings, while young Richard Duke of Gloucester, who was only eighteen years of age, had charge of the right wing. A strong body of infantry was kept in reserve. The King ordered strict silence to be observed throughout the night.
