 In June, William sent Count Zuylestein to England, ostensibly to congratulate James on the birth of the Prince of Wales but in reality to communicate with William's associates.Only after the Prince of Wales had been born in June, however, and many suspected he was supposititious, did the Immortal Seven (who consisted of one bishop and six nobles) decide to comply, with the letter to William dated 18 June (Julian calendar), reaching him in The Hague on 30 June, and dispatched by Rear Admiral Herbert, disguised as a common sailor.The Seven consisted of Lord Shrewsbury, Lord Devonshire, Lord Danby, Lord Lumley, Henry Compton, Edward Russell, and Henry Sydney.
