YES, the lost of Commodore Bonte was a huge price for Kriegsmarine destroyers.
He was on board Z-21 Wilhelm Heidkamp mortally wounded by a torpedo fired by HMS Hardy on Narvik harbour during the first battle on April 10th, 1940.
But Capt. Warburton-Lee was not going to have different destiny, as he was on board HMS Hardy and was sunk and died soon after too.
Those guys put together a big fight, without big ships, but with lots of courage.
