The young king, hopeful of victory and full of enthusiasm, rode speedily out at the head of his troops and placed them at their various stations. Scarcely had he done so, when he became aware that the main body of the enemy had opened an artillery fire on Fort Royal, which guarded the city on the south-east side. He therefore galloped back in hot haste to headquarters, and reconnoitred the advanced posts eastward of the city, in full front of the enemy's fire. Meanwhile Montgomery, having exhausted his ammunition, was obliged to retreat in disorder from Powick Bridge, followed by the Cromwellians. The king now courageously resolved to attack the enemy's camp at Perry Wood, which lay south-east of Worcester. Accordingly he marched out with the flower of his Highland infantry and the English cavaliers, led by the Dukes of Hamilton and Buckingham.
Cromwell, seeing this, hastened to intercept the king's march, whereon a fierce battle was bravely fought on either side.
Nothing could be more valiant than the conduct of the young king, who showed himself wholly regardless of his life in the fierce struggle for his rights. Twice was his horse shot under him; but increasing danger seemed but to animate him to greater daring.
So bravely did his army fight likewise, that the Republicans at first gave way before them. For upwards of four hours the engagement raged with great fierceness. Cromwell subsequently declared it was "as stiff a contest as he had ever seen," and his experience was great. Success seemed now to crown the Royalists, anon to favour the Roundheads. The great crisis of the day at length arrived: the Cromwellians began to waver and give way just as the Royalist cavalry had expended their ammunition; the king had still three thousand Scotch cavalry in the rear under the command of Leslie, who had not yet been called into action. He therefore ordered them to advance; but, to his horror, not one of these men, who had looked on as passive spectators, made a movement. In this hour, when victory or defeat hung upon a thread the Scots ignominiously failed their king. Charles instantly saw he was undone. The English cavalry continued to fight bravely, in their desperation using the butt ends of their muskets; but they were gradually compelled to give way before the enemy, who, seeing their condition, had renewed the attack. The Royalists therefore fell back into the city.
When the king re-entered Worcester he saw before him a scene of the most disastrous confusion. Royalists and Republicans encountered and fought each other in every thoroughfare; the air was filled with the report of muskets, the imprecations of soldiers, the groans of wounded men, and the shrieks of women.
The streets ran red with blood. At such a sight his heart sank within him, but, manning himself for fresh efforts, he called his troops together and sought to incite them with courage to make a final charge. "I would rather," he cried out, "you would shoot me than keep me alive to see the sad consequences of this fatal day." Those who heard him were disheartened: it was too late to retrieve their heavy losses: most of them refused to heed him;many sought safety in flight. Then the young king's friends, gathering round, besought him to make good his escape; and accordingly, with a sad heart, he rode out of St. Martin's Gate humbled and defeated. In order to cover his retreat from the enemy now advancing, my Lord Cleveland, Sir James Hamilton, Colonel Careless, and some other worthy gentlemen defended Sudbury Gate, towards which the main body of the Republicans approached. They held this position a sufficient time to gain the end for which it was undertaken. But at length the Republicans, forcing open the gate, marched upon the fort, defended by fifteen hundred soldiers under Colonel Drummond.
This loyal man refusing to surrender, the fort was speedily stormed; and he and those of his men who survived the attack were mercilessly put to the sword.
