 After his release Robert Dudley was short of money and he and Amy were helped out financially by their families. Their lifestyle had to remain modest, though, and Lord Robert (as he was known) was heaping up considerable debts. Sir John Robsart died in 1554; his wife followed him to the grave in the spring of 1557, which meant that the Dudleys could inherit the Robsart estate with the Queen's permission. Lady Amy's ancestral manor house of Syderstone had been uninhabitable for many decades, and the couple were now living in Throcking, Hertfordshire, at the house of William Hyde, when not in London. In August 1557 Robert Dudley went to fight for Philip II of Spain (who was then Mary I's husband) at the Battle of St. Quentin in France. From this time a business letter from Amy Dudley survives, settling some debts of her husband's in his absence, "although I forgot to move my lord thereof before his departing, he being sore troubled with weighty affairs, and I not being altogether in quiet for his sudden departing".
