Prince Harry was 'pulled aside' by sergeant over innocent mistake

Prince Harry talks about his tough days in the British Army in 2006. The Duke of Sussex, who served a decade in the military, talks about various types of pain he had to endure in order to survive. He pens in 'Spare': "They used a variety of approaches.

Physical duress, psychological intimidation--and humor? I remember one color sergeant pulling me aside. Mr.

Wales, I was on guard one day at Windsor Castle, wearing my bearskin, and along came a boy who kicked gravel on my boots! And that boy...was YOU!" Harry continues: "He was joking, but I wasn't sure I should laugh, and I wasn't sure it was true.

I didn't recognize him, and I certainly didn't remember kicking gravel on any guardsmen.

But if it was true, I apologized and hoped we could put it behind us."
