The King, therefore, found himself in a condition to face the Earl of Warwick, who, being reënforced by his son-in-law the Duke of Clarence, and his brother the Marquis of Montagu, took post at Barnet, in the neighborhood of London. Warwick was now too far advanced to retreat, and, as he rejected with disdain all terms of peace offered him by Edward and Clarence, he was obliged to hazard a general engagement. The battle was fought with obstinacy on both sides. The two armies, in imitation of their leaders, displayed uncommon valor; and the victory remained long undecided between them. But an accident threw the balance to the side of the Yorkists. Edward's cognizance was a sun; that of Warwick a star with rays; and the mistiness of the morning rendering it difficult to distinguish them, the Earl of Oxford, who fought on the side of the Lancastrians, was by mistake attacked by his friends and chased off the field of battle. Warwick, contrary to his more usual practice, engaged that day on foot, resolving to show his army that he meant to share every fortune with them, and he was slain in the thickest of the engagement; and as Edward had issued orders not to give any quarter, a great and undistinguished slaughter was made in the pursuit. There fell about one thousand five hundred on the side of the victors. The same day on which this decisive battle was fought, Queen Margaret and her son, now about eighteen years of age and a young prince of great hopes, landed at Weymouth, supported by a small body of French forces. When this Princess received intelligence of her husband's captivity, and of the defeat and death of the Earl of Warwick, her courage, which had supported her under so many disastrous events, here quite left her; and she immediately foresaw all the dismal consequences of this calamity. At first she took sanctuary in the Abbey of Beaulieu; but being encouraged by men of rank, who exhorted her still to hope for success, she resumed her former spirit and determined to defend to the utmost the ruins of her fallen fortunes. She advanced through the counties of Devon, Somerset, and Gloucester, increasing her army on each day's march, but was at last overtaken by the rapid and expeditious Edward at Tewkesbury, on the banks of the Severn. The Lancastrians were here totally defeated; the Earl of Devonshire and Lord Wenlock were killed in the field; the Duke of Somerset and about twenty other persons of distinction, having taken shelter in a church, were surrounded, dragged out, and immediately beheaded; about three thousand of their side fell in battle; and the army was entirely dispersed.
