Being the Queen and the Duke of Edinburgh’s third child, Prince Andrew was born into at a time when her Majesty had settled into her role.
Therefore she was able to spend more time with both him and his younger brother, Prince Edward, than with his older siblings, Prince Charles and Princess Anne.
However, the horses at Windsor Castle were also very precious to the Queen, and as a result, the stable staff would not tolerate Prince Andrew’s attack.
"When he refused to stop, two grooms picked him up, threw him into the dung heap and shovelled manure all over him," wrote Seward.
Prince Andrew - who shares Princess Beatrice and Princess Eugenie with Sarah Ferguson - was left feeling humiliated as he was yet to experience such treatment.
"The Prince was too shocked to cry, but the impact of his humiliation hit him and, when he managed to extract himself from the foul-smelling mess, he ran as fast as he could up the hill to the castle saying: ‘I’ll tell my mummy.’"
However, the royal biographer said the grooms at Windsor castle were never reprimanded by the British monarch.
"No one knows if he ever did but there were no repercussions."
Regardless, the Royal Family have supported Prince Andrew in recent weeks.
Juan Alessi, an ex-employee of Epstein, claimed that Prince Andrew enjoyed massages from teenage girls at Epstein's Palm Beach mansion.
A statement from Buckingham Palace said the Duke of York was "appalled" by recent reports of the Mr Epstein’s alleged crimes.
The statement read: "His Royal Highness deplores the exploitation of any human being and the suggestion he would condone, participate in or encourage any such behaviour is abhorrent."
