[3] While serving as an officer in the Staffordshire Militia at Windsor, Disbrowe became a friend of the king.
[1] This led to a variety of royal appointments, including Equerry to George III, Vice-Chamberlain to Queen Charlotte, and Master of St Katharine's by the Tower.
[2] His regiment was given the title of the King's Own (1st Staffordshire) Militia, and was thereafter frequently on duty at Windsor Castle, Kew Palace, or at Weymouth when the Royal Family was in residence.
His career was marked by punctual attendance, generally silent support for the government, and opposition to Catholic relief.
While serving as MP, he was the first to inform ministers of the king's impending relapse into insanity in 1810, which would lead to the regency of the Prince of Wales.
