The Earl of Kent left no legitimate son to inherit his honors; but he left an illegitimate son, named Thomas Neville, and known, after the fashion of the age, as "The Bastard of Falconbridge." The misfortune of Falconbridge's birth, of course, prevented him from becoming his father's heir; but, being "a man of turbulent spirit and formed for action," he had no idea of passing his life in obscurity. His relationship to Warwick was not distant; and "The Stout Earl," duly appreciating the courage and vigor of his illegitimate kinsman, nominated him vice-admiral, and appointed him to prevent Edward receiving any aid from the Continent.

While Warwick lived, Falconbridge appears to have executed his commission on the narrow seas with fidelity and decorum. But when Barnet had been fought, and the vice-admiral had no longer the fear of the king-maker before his eyes, the narrow seas saw another sight. Throwing off all restraint, he took openly to piracy, and, joined by some malcontents from Calais, went so desperately to work, that in a marvelously short space of time he made his name terrible to skippers and traders. Falconbridge was not, however, content with this kind of fame. He had always believed himself destined to perform some mighty achievement, and he now found his soul swelling with an irresistible ambition to attempt the restoration of Lancaster. The peril attending such an exploit might, indeed, have daunted the boldest spirit; but the courage of the Bastard was superlative, and his audacity was equal to his courage.

The enterprise of Falconbridge was not at first so utterly desperate as subsequent events made it appear. The Lancastrians were not yet quite subdued. Oxford was still free and unsubdued; Pembroke was in arms on the marches of Wales; and the men of the north, on whom Edward's hand had been so heavy, were arming to take revenge on their tyrant, and liberate from his grasp the woman who, with her smiles and tears, had in other days tempted them to do battle in her behalf. If, under these circumstances, Falconbridge could take Henry out of prison, proclaim the monk-monarch once more in London, and send northward the news of a Lancastrian army being in possession of the capital, he might change the destiny of England, and enroll his own name in the annals of fame.

No time was lost in maturing the project. Landing at Sandwich, Falconbridge was admitted into Canterbury, and prepared to march upon the metropolis. His adventure soon began to wear a hopeful aspect. Indeed, his success was miraculous; for, as he made his way through Kent, the army, which originally consisted of the desperadoes of the Cinque Ports and the riff-raff of Calais, swelled till it numbered some seventeen thousand men. Posting this formidable host on the Surrey side of the Thames, and, at the same time, causing his ships to secure the river above St. Katherine's, Falconbridge demanded access to the city, that he might take Henry out of the Tower, and then pass onward to encounter the usurper.

The mayor and aldermen, however, sorely perplexed, determined to stand by the house of York, and sent post-haste to inform the king that London was menaced by land and water, and to implore him to hasten to the relief of his faithful city. Edward, who, to awe the northern insurgents, had proceeded as far as Coventry, forthwith sent fifteen hundred men to the capital; and, on meeting the Earl of Northumberland, who came to assure him of the peace of the north, the king turned his face southward, and hurried toward London.

Meanwhile the patience of Falconbridge had given way. Enraged at the refusal of the Londoners to admit his army, and anxious to gratify the appetite of his followers for plunder, the Bastard expressed his intention of passing the Thames with his army at Kingston, destroying Westminster, and then taking revenge on the citizens of London for keeping him without their gates. Finding, however, that the wooden bridge at Kingston was broken down, and all the places of passage guarded, he drew his forces into St. George's Fields, and from that point prepared to carry London by assault.

His plan thus formed, Falconbridge commenced operations with characteristic energy. After carrying his ordnance from the ships, he planted guns and stationed archers along the banks of the Thames. At first considerable execution was done. Many houses were battered down by the ordnance, and London experienced much inconvenience from the flight of arrows; but the citizens soon showed that this was a game at which two parties could play. Having brought their artillery to the river-side, and planted it over against that of their assailants, they returned the fire with an effect so galling, that the adherents of the vice-admiral found their position intolerable, and retreated in confusion from their guns.

Falconbridge was not the man to despair early of the enterprise upon which he had ventured. Seeing his men fall back in dismay, he resolved on prosecuting the assault in a more direct way, and on going closely to work with his antagonists. He resolved, moreover, on making a great attempt at London Bridge, and, at the same time, ordered his lieutenants—Spicing and Quintine—to embark three thousand men, pass the Thames in ships, and force Aldgate and Bishopgate. The desperadoes, crossing the river, acted in obedience to their leader's orders, and London was at once assailed suddenly at three separate points. But the Londoners continued obstinate. Encouraged by the news of Edward's victory, and incited to valor by the example of Robert Basset and Ralph Jocelyne, aldermen of the city, they faced the peril with fortitude, and offered so desperate a defense, that seven hundred of the assailants were slain. Repulsed on all points, and despairing of success, the Bastard was fain to beat a retreat.

Baffled in his efforts to take the capital by storm, Falconbridge led his adherents into Kent, and encamped on Blackheath. His prospects were not now encouraging; and for three days he remained in his camp without any new exploits. At the end of that time he learned that Edward was approaching, and doubtless felt that the idea of trying conclusions at the head of a mob with the army that had conquered at Barnet and Tewkesbury was not to be entertained. The undisciplined champions of the Red Rose, indeed, dispersed at the news of Edward's coming, as pigeons do at the approach of a hawk; and their adventurous leader, having taken to his ships, that lay at Blackwall, sailed for Sandwich.
