The traditional color ceremony, which normally features hundreds of military personnel and thousands of spectators, was excluded because of the threat of coronavirus.
But the Household Division – made up of the most prestigious regiments of the British Army – has a close affinity with the Queen and was keen to mark this milestone with a ceremony described as a mini-troop.
L/Cpl Chusa Siwale, 29, from Zambia, played a central role in the ceremony, which was created by WOI (GSM) Andrew Stokes.
The custodian, whose regiment is part of the Household Division, said it was a “huge privilege” to have the key role of executing the batsman’s call during a difficult time for the country.
“Just four weeks ago, I participated in the analysis of key workers for Covid-19 as part of the Welsh Guards’ contribution to the fight against the virus; now I’m on parade performing in front of His Majest,” he said. “It’s a very proud day for me.”
The ceremony began when the Queen took her place on a platform in the quadrangle of Windsor Castle and the royal salute was given by the troops and the national anthem was played.
An event such as this one marking the Sovereign’s birthday has not been held in Windsor since 1895, when a ceremony was held in honour of Queen Victoria.
Normally, soldiers stand side by side during exercises or when trained on the parade ground, allowing them to maintain the “band-aid” – by staying in line with each other.
But according to Covide-19 guidelines, they stood 2.2 metres apart, measured by three turns in the gsm rhythm.
