captain of the guard) is based there, as are the regiment's colours. When the Sovereign is in residence, the King's Guard numbers three officers and forty other ranks, with four sentries each posted at Buckingham Palace (on the forecourt) and St James's Palace (two in Friary Court, two at the entrance to Clarence House). This reduces to three officers and 31 ORs, with two sentries each, when the Sovereign is not in residence. The King's Guard is not purely ceremonial. They provide sentries during the day and night, and during the later hours, they patrol the grounds of the Palace. Until 1959, the sentries at Buckingham Palace were stationed outside the fence. This stopped following an incident involving a female tourist and a Coldstream Guardsman – due to the continued pestering by tourists and sightseers, the guardsman kicked the tourist on the ankle as he marched. The tourist made a complaint to the police and the sentry was confined to barracks for ten days. Not long after, the sentries were moved inside the fence. Detachments There are two detachments of the King's Guard in London, one each for Buckingham Palace and St James's Palace, under the command of the captain of the King's Guard. Because St James's Palace is still the official residence of the court, it is here that the colour is lodged and the captain of the guard establishes his headquarters. The King's Guard in London changes in the forecourt of Buckingham Palace at 11:00 am every day in early summer and four times per week otherwise. The St James's Palace detachment of the King's Guard, led usually by the corps of drums, and bearing the colour (if the King is in residence, then this will be the King's colour; if he is not, then it is the regimental colour), marches along the Mall to Buckingham Palace, where the Buckingham Palace detachment has formed up to await their arrival. These two detachments are the old guard. Meanwhile, the new guard is forming and is awaiting inspection by the adjutant on the parade square at Wellington Barracks. The band, having been inspected by the adjutant, forms a circle to play music whilst the new guard is inspected. The guard provides a full military band consisting of no fewer than 35 musicians (usually from one of the Guard regiments) led by their director of music. When the new guard is
