“The brother I’d escorted into Westminster Abbey that morning was gone — forever,” Harry wrote. “Who could deny it? He’d never again be first and foremost Willy. We’d never again ride together across the Lesotho countryside with capes blowing behind us. We’d never again share a horsey-smelling cottage while learning to fly. Who shall separate us? Life, that’s who.”

Prince Harryalso claimed thatPrince Williamand Kateencouraged him to wear his infamous Nazi costumein 2005. Harry was 20 at the time, and the photo of him in a military shirt and red swastika armband holding a drink and a cigarette made headlines across the world.

“I phoned Willy and Kate, asked what they thought. Nazi uniform, they said,” wrote Harry, adding that when he brought the costume home and tried it on, “They both howled. Worse than Willy’s leotard outfit! Way more ridiculous! Which, again, was the point.”

Harry has since expressed deep remorse over the outfit, calling the decision “one of thebiggest mistakes of my life” in the Netflix docuseriesHarry & Meghan.

Prince HarrytellsPEOPLE in an exclusive interviewthat being known as the “spare” to his older brother throughout his life was challenging.

“For as long as I can remember, I’ve heard and seen the term ‘spare’ to describe me. I knew the only way I could write this book with a good conscience would be if I openly and honestly confronted my experiences and leaned into that which once held me back—including this term,” he says. “While I know much of my life may seem unrelatable, I do think most siblings can relate to struggling with comparisons, and my brother and I are no exception.”

Kate andPrince Williamhave kept a low profile in recent weeks after celebrating the holidays with the royal family.
