The English Civil War Society will be marching through central London to commemorate the martyrdom of King Charles I in 1649.
Around 500 of their members will be dressed up as soldiers from the King's Army, all clothed and equipped in Civil War style, to mark one of the most momentous events in English history.
March from St. James's Palace to Horse Guards
The route follows in the footsteps of the King's final journey from St. James's Palace to Banqueting House, where he was put to death on a scaffold in the street.
At 11.15 AM the army will enter the Mall and begin a slow, solemn march to the beat of muffled drums, carrying a wreath that 'Remembers His Majestie's Horrid Murder'.
At around 12 noon they will reach Horse Guards and perform a religious drumhead service on the parade ground, during which they will troop their colour (parade their regimental flag), administer an Oath of Loyalty, and present some awards.
A small contingent will then march through the central arch and form up opposite Banqueting House.
Wreath laying and mass at Banqueting House
Prayers will then be said in front of the King's bust above the door, followed by a wreath-laying ceremony. They will then head inside to take part in a special mass.
At around 12.30 PM another wreath will be placed by the King's equestrian statute on that little traffic island at the top end of Whitehall (in front of Nelson's Column).
They will then march back to St. James's Palace giving great shouts of acclamation to their martyred King.
