Cromwell was somewhat disconcerted by the unlooked-for advantage gained by Charles, but he quickly brought his disordered troops to their ranks, and prepared to bring forward his reserves. Like Charles, he looked down to the Blockhouse fields to see what Lesley would do, but was speedily reassured by finding the Scottish horse remain motionless.
"The men of Sechem have dealt treacherously with Abimelech," he said, with a stern smile. "Had Lesley come to his master's aid in time, he might have given me some trouble."
Detaching troops on either side to prevent a junction between the three parties of Royalists, he himself made a determined attack on the king.
The onset was terrible, but Charles and his Cavaliers bore it firmly, and maintained their ground, giving abundant proofs of valour, and showing of what stout stuff they were made, since they could thus resist the attack of Cromwell's veteran troops.
The conflict lasted for a considerable time—much longer, indeed, than Cromwell expected—but when Lambert arrived with his troops it became too unequal, and the Cavaliers were forced to give way. Besides, their ammunition was completely exhausted, and they were obliged to fight with the butt-ends of their muskets. After a most obstinate but ineffectual resistance, they retreated in disorder towards the city.
No junction had taken place between the battalions under the Duke of Hamilton and the Earl of Derby, but neither of these leaders were more successful than the king, though both fought valiantly. The Duke of Hamilton routed a troop of horse, but in a subsequent encounter his horse was shot under him, and he himself was so severely wounded, that he had to be taken from the field, and was conveyed to the Commandery. Sir John Douglas was likewise mortally wounded, and Sir Alexander Forbes, disabled by a shot through both legs, was left in this lamentable condition in Perry Wood during the whole night. Next day he was discovered by the enemy and taken prisoner. Both the Earl of Derby and Roscarrock escaped unhurt, but the battalion commanded by the earl was routed after a gallant fight.
Overpowered on all sides, the Royalists, after sustaining fearful loss, were compelled to retreat into the city. Lesley, who had taken no part whatever in the fight, finding that the day had gone against the king, moved his regiment towards Barbourne Bridge, about a mile on the north of the city, and close to Pitchcroft.
No sooner did Cromwell's engineers regain possession of the great guns than they began to cannonade Fort Royal with redoubled fury. Under this tremendous fire a strong storming party was detached to take the fort, with orders from the Lord General to put all the troops within it to the sword unless they surrendered. The barbarous order was executed. The fort being carried by storm after an obstinate resistance, no quarter was given to its brave defenders. The guns of the fort were then turned upon the city, and being so close to it, caused terrible havoc, and drove all the artillerymen from the walls.
But we must now return to the king. So long as a chance was left him, Charles fought valiantly, and during the retreat, though he failed to rally his disordered troops, he turned several times to face the enemy.
While thus braving the foe for the last time he was left alone, none of his attendants being aware that he had stopped. From the richness of his accoutrements he was at once recognised, and fierce cries were raised:
