Witness the colourful parades and precision drill work of more than 400 military personnel in the biggest ever Beating Retreat at Horse Guards Parade.
Celebrating the birthday of His Royal Highness Prince Philip, Duke of Edinburgh (who is Captain General of the Royal Marines), this spectacular military ceremony is carried out by the Massed Bands of Her Majesty's Royal Marines.
This year also marks the 350th anniversary of the Royal Marines, so there's an extra special line-up featuring the Marines themselves, and Marine Corps bands from the United States and The Netherlands.
This pageantry originated during the early years of organised warfare, when beating or sounding retreat using drums called an end to the day of fighting. It signalled that the soldiers should return to their camp and that they should mount a guard for the night.
As impressive now as it was back then, this bright and stirring spectacle is a reminder of the proud traditions of the British military.
