Dressed in woolen tunics and bearskin hats, several British soldiers paid tribute to Prince William on Saturday amid the scorching heat.
At least three guardsmen fainted as the heir to the throne, an honorary colonel of the Welsh Guards, reviewed more than 1,400 soldiers from the Home Office and the Household Artillery during the parade known as Colonel’s Review.
Temperatures will hit 30C (86F) in London on Saturday.
Later, William wrote on Twitter: “Thank you very much to every soldier who participated in the colonel’s review in the scorching heat this morning. The conditions were difficult, but you all did a good job.”
The event is a rehearsal for Trooping the Color, the annual military parade held every June to mark the monarch’s official birthday. King Charles III will preside over the ceremony on 17 June.
