An enthusiastic response arose from the ranks of the Lancastrians as their heroic queen concluded her spirit-stirring address; and the warriors of the Red Rose indicated, by signs not to be mistaken, their alacrity to fight to the death for the rights of such a mother and such a son. Perhaps, at that moment, Margaret, infected with the excitement which her own eloquence had created, almost persuaded herself to hope. No hour was that, however, to indulge in day-dreams. Ere the enthusiasm of the Lancastrians had time to die away, Richard of Gloucester had advanced his banner to their camp, and the troops under the young duke were storming the intrenchments.
Gloucester, as leader of the Yorkist van, found himself opposed to the Lancastrians whom Somerset commanded in person; and, the ferocity of his nature being doubtless inflamed by the hereditary antipathy of the house of York to the house of Beaufort, he made a furious assault. The onslaught of the stripling war-chief, however, proved of no avail; for the nature of the ground was such as to prevent the Yorkists from coming hand to hand with their foes, while the Lancastrians, posted among bushes and trees, galled their assailants with showers of arrows. Gloucester was somewhat cowed, but his guile did not desert him. He assumed the air of a man who was baffled, pretended to be repulsed, and, retiring from the assault, contented himself with ordering the artillery, with which the Yorkists were better provided than their foes, to play upon the Lancastrian ranks.
The aspect of the battle was now decidedly in favor of the Red Rose, and such as to cause the Yorkists some degree of anxiety. What the Lancastrians wanted was a war-chief of courage and experience, and Somerset neither had the talents nor the experience requisite for the occasion. At the head of that host on the banks of the Severn, such a man as the fifth Henry, or John, Duke of Bedford, might, by a decisive victory, have won back Margaret's crown. But the grandson of Katherine Swynford had not been intended by God and nature to cope with the royal warrior who laid Warwick low.
Somerset had still to learn his incapacity for the part he had undertaken to enact. As yet he was under the influence of such a degree of vanity as prompted him to the rashest courses. Elate at Gloucester's retreat, and concluding that a determined effort would render the Lancastrians victorious, the shallow duke led his men through the openings that had been left in their intrenchments. Descending from the elevated ground, he charged Edward's centre host with violence, drove that part of the Yorkist army back, and then, with infinitely less prudence than presumption, followed the wily Gloucester into the open meadows.
Once fairly away from his intrenchments, the Lancastrian leader found too late the error he had committed. Gloucester's stratagem had been attended with a success which even he could hardly have anticipated. Suddenly wheeling round and shouting their battle-cry, the boy-duke and the Yorkists turned upon their pursuers with the fury of lions; and, at the same time, the two hundred spearmen who had been sent to guard against an ambuscade in Tewkesbury Park came rushing to the conflict, and made a vigorous attack upon Somerset's flank. Taken by surprise, the Lancastrian van fled in disorder. Some made for the park; some ran toward the meadows; others flung themselves into the ditches; and so many were beaten down and slain where they fought, that the greensward was crimsoned with gore.
Gloucester did not pause in the work of destruction. After cheering on his men to the carnage, he pursued Somerset up the hill, availed himself of the Lancastrians' confusion to force his way through their intrenchments, and carried into their camp that terror with which his grisly cognizance seldom failed to inspire his enemies.
The plight of the Lancastrians now became desperate. Somerset, having lost his followers, lost his temper, and with it every chance of victory. Indeed, the duke appears to have acted the part of a madman. On reaching the camp, flushed and furious, he looked around for a victim to sacrifice to his rage, and made a selection which was singularly unfortunate for the Lancastrians. Lord Wenlock, it seems, had not left the camp to support Somerset's charge; and the duke, bearing in mind how recently that nobleman had been converted from the Yorkist cause, rushed to the conclusion that he was playing false. A fearful scene was the result. Riding to the centre division of the Lancastrians, the exasperated Beaufort reviled Lord Wenlock in language too coarse to have been recorded, and, after denouncing the aged warrior as traitor and coward, cleft his skull with a battle-axe.
No incident could have been more unfavorable to the fortunes of the Red Rose than Wenlock's fall by the hand of Somerset. A panic immediately seized the Lancastrians; and, ere they could recover from their confusion, King Edward perceived his advantage, cheered his men to the onslaught, spurred over hedge and ditch, and dashed, on his brown charger, fiercely into the intrenched camp. Irresistible we can well imagine the onset of that horse and that rider to have been—the strong war-steed, with his frontal of steel, making a way through the enemy's disordered ranks, and the tall warrior dispersing all around with the sweep of his terrible sword. Vain was then the presence of the Prince of Wales, gallant as the bearing of the royal boy doubtless was. Indeed, all the princes of John of Gaunt's lineage could not now have turned the tide of fight. After a faint struggle, the Lancastrians recoiled in consternation; and, throwing down their arms, fled before Edward and his knights as deer before the hunters. The rout was rapid and complete. The field presented a fearful scene of panic, confusion, and slaughter. Some of the vanquished ran for refuge into Tewkesbury; others betook themselves for safety to the abbey church; and many, hotly pursued and scarcely knowing whither they went, were drowned "at a mill in the meadow fast by the town."
Somerset, on seeing the ruin his rashness had brought on his friends, fled from the scene of carnage. The duke ought not, perhaps, to have avoided the destruction to which he had allured so many brave men. The chief of the Beauforts, however, had no ambition to die like the great earl whom he had deserted at Barnet, nor to fall on the field to which he had challenged his hereditary foe. It is wonderful, indeed, that a man who had known little of life save its miseries should have cared to survive such a defeat; but Somerset, whatever his other qualities, had none of that spirit which, at Bannockburn, prompted Argentine to exclaim, "'Tis not my wont to fly!" At Hexham and at Barnet, Somerset's principal exploits had consisted of availing himself of the speed of his horse to escape the foe; and at Tewkesbury he rushed cravenly from the field, on which, a few hours earlier, he had boastfully declared that he would abide such fortune as God should send. The Prior of St. John, Sir Gervase Clifton, Sir Thomas Tresham, and a number of knights and esquires likewise sought safety in flight.
