Immediately after Edward's flight had left the kingdom at Warwick's disposal, that nobleman hastened to London; and taking Henry from his confinement in the Tower, into which he himself had been the chief cause of throwing him, he proclaimed him King with great solemnity. A parliament was summoned, in the name of that Prince, to meet at Westminster. The treaty with Margaret was here fully executed; Henry was recognized as lawful king; but, his incapacity for government being avowed, the regency was intrusted to Warwick and Clarence till the majority of Prince Edward; and in default of that Prince's issue, Clarence was declared successor to the crown. The ruling party were more sparing in their executions than was usual after any revolution during those violent times. The only victim of distinction was John Tibetot, Earl of Worcester. All the other considerable Yorkists either fled beyond sea or took shelter in sanctuaries, where the ecclesiastical privileges afforded them protection. In London alone it is computed that no less than two thousand persons saved themselves in this manner, and among the rest Edward's Queen, who was there delivered of a son, called by his father's name. Queen Margaret had not yet appeared in England, but, on receiving intelligence of Warwick's success, was preparing with Prince Edward for her journey. All the banished Lancastrians flocked to her, and, among the rest, the Duke of Somerset, son of the Duke beheaded after the battle of Hexham. This nobleman, who had long been regarded as the head of the party, had fled into the Low Countries on the discomfiture of his friends; and as he concealed his name and quality, he had there languished in extreme indigence. But both Somerset and Margaret were detained by contrary winds from reaching England, till a new revolution in that kingdom, no less sudden and surprising than the former, threw them into greater misery than that from which they had just emerged. The Duke of Burgundy equipped four large vessels, in the name of some private merchants, at Terveer, in Zealand; and, causing fourteen ships to be secretly hired from the Easterlings, he delivered this small squadron to Edward, who, receiving also a sum of money from the Duke, immediately set sail for England, 1471.
