Fifteen minutes before the explosion, de la Penne asked to speak to the Valiant's captain and informed him of the imminent explosion but refused to give other information. He was returned to the compartment and neither he or Bianchi were injured by the detonation of the mine. The other four torpedo-riders were also captured, but their mines sank Valiant, the battleship Queen Elizabeth, the Norwegian tanker Sagona and badly damaged the destroyer HMS Jervis.
