Re: British battleship HMS Barham explodes after being torpe
The HMS Barham Association website is available via this link. Coincidentally, the funeral of one of the few remaining survivors, former CPO(CD1) Arthur 'Ginger' Bryant BEM, was held only last week. He had quite a life and career after the war too. More details and photos in the entries for 19 & 29 Jan 08 on the 'Latest News' page of the MCDOA website.
A boiler explosion would have been contained within the ship, lethal to those in the boiler room(s) but with little external indication. The catastrophic explosion of HMS Barham was caused by the detonation of high explosives; a lot of high explosives.
