The Duke of York said he returned from the Falklands War "a changed man" in a piece of writing posted to his ex-wife's Instagram account.
Prince Andrew, who reached a multimillion-pound out-of-court settlement in a civil sexual assault case a few weeks ago, wrote more than 700 words about his experience in the Falklands.
The Queen's second-eldest son flew missions as a Sea King helicopter pilot during the conflict.
