Fate: Possibly sunk off Penang by Japanese A/S aircraft on or about 11th January 1945. On 3rd January 1945 the Submarine left Trincomalee in Ceylon (now Sri Lanka) for her 23rd War Patrol (4th in the Far East) with orders to lay a minefield off Penang. On 9th Jan 1945, Lt. Cdr. H B Turner, DSC is understood to have reported by signal that he had successfully laid her mines off Penang. On 13th January 1945, HMS Stygian was sent a signal informing her that Porpoise was in trouble 17 miles northwest of Pulo Perak). This information came from an Ultra decrypt (now in the National Archives in London) reporting that on 11th January a Nakajima B6N2 bomber had attacked a Submarine, dropping two 60kg bombs. Further bombing attacks we made later but there was no further contact. Japanese records show that a submarine was spotted and bombed by aircraft in the vicinity of Penang. Although not destroyed in this attack, the submarine was wounded and leaking oil that left a trail for the Japanese anti-submarine forces to follow as they closed in for the kill. HMS Porpoise was later declared overdue and then as lost with all hands. |

A first hand account of the German U-boat battles of World War II, by one of the very few surviving commanders.
This is a story of triumph, disaster and eventual survival against all odds. Herbert Werner was one of the few U-boat commanders whose skill, daring and incredible luck saw him safely through to the end of the war. His is an epic and chilling description of the fearful havoc wrought by one small U-boat on the Atlantic convoys.
But easy success ebbed away in the face of ever-improving Allied detection and attack techniques. The hunters became the prey, to suffer appalling losses. Of 842 U-boats launched 779 were sunk, 'iron-coffins' to 28,000 men.
Herbert Werner's graphic account of war waged from beneath the sea, of horror and cold, cruel death, is dedicated to the seamen of all nations who died in the Battle of the Atlantic.
