The Royal Family on Instagram: "🇺🇸 🇬🇧 This afternoon, a Beating Retreat ceremony was held at Windsor Castle to mark President Trump’s State Visit. The ceremony has its origins in the early years of organised warfare when the beating of drums and the parading of Post Guards heralded the closing of camp gates and the lowering of flags at the end of the day."
