A Child's History of England by Charles Dickens

The late King's eldest son, the Prince of Wales, called Edward after him, was only thirteen years of age at his father's death. He was at Ludlow Castle with his uncle, the Earl of Rivers. The prince's brother, the Duke of York, only eleven years of age, was in London with his mother. The boldest, most crafty, and most dreaded nobleman in England at that time was their uncle Richard, Duke of Gloucester, and everybody wondered how the two poor boys would fare with such an uncle for a friend or a foe.

The Queen, their mother, being exceedingly uneasy about this, was anxious that instructions should be sent to Lord Rivers to raise an army to escort the young King safely to London. But, Lord Hastings, who was of the Court party opposed to the Woodvilles, and who disliked the thought of giving them that power, argued against the proposal, and obliged the Queen to be satisfied with an escort of two thousand horse. The Duke of Gloucester did nothing, at first, to justify suspicion. He came from Scotland (where he was commanding an army) to York, and was there the first to swear allegiance to his nephew. He then wrote a condoling letter to the Queen-Mother, and set off to be present at the coronation in London.
