Using information from Italian submarine Galileo Galilei captured on June 19, British sloop HMS Shoreham locates Italian submarine Evangelista Torricelli and forces her to the surface with depth charges. Evangelista Torricelli bravely engages 3 British destroyers HMS Kandahar, Kingston and Khartoum with her deck gun but is sunk near Perim Island at the mouth of the Red Sea. Later, HMS Khartoum is badly damaged when one of her own torpedoes explodes on deck (1 dead). Khartoum is beached on Perim Island to prevent sinking, but she is a total loss and is never repaired. http://www.naval-history.net/xGM-Chrono-10DD-39K-Khartoum.htm
