Members of the Armed Forces have taken part in a special military pageant to celebrate the Queen's platinum jubilee.
The star-studded extravaganza also featured some of the world's leading performers, including Top Gun legend Tom Cruise and British cinema icon Dame Helen Mirren.
Marking the end of this year's Royal Windsor Horse Show, 'A Gallop Through History' included thrilling displays by the Household Cavalry Mounted Regiment and the Royal Cavalry of Oman.

Taking to the stage to introduce 'the drive', as they are known, this year led by Major Marc O'Dell, he said the soldiers were about to provide "one of the most enthralling, thrilling, heart-in-mouth displays".
The star added: "It takes huge courage and discipline to do what they do, galloping with guns that were fired in the battles of the First World War, weighing one-and-a-half tonnes, with no brakes.
"The drive demonstrates absolute trust between horse and rider," he added.
A tri-service guard of honour featuring the Coldstream Guards, RAF Regiment and Royal Navy was in place for the Queen's arrival, signalled by the national anthem being played by military musicians.
Despite ongoing mobility issues, the Queen walked to her seat in the Royal box after being driven into the arena escorted by mounted divisions of the Household Cavalry.
Joined by her youngest son, the Earl of Wessex, the show reflected the Queen's life-long passion for horses.
