SM U-93 was one of the 329 submarines serving in the Imperial German Navy in World War I. U-93 was engaged in the naval warfare and took part in the First Battle of the Atlantic.[1]

Since Feb. 1917 she was commanded by the late author of books (e.g. U boat 202. The war diary of a german submarine, 1919) and experienced submarine commander Edgar von Spiegel von und zu Peckelsheim

On 30 April 1917 about 180 miles south of Ireland, in the Atlantic, U-93 attacked HMS Prize, a three-masted topsail schooner (one of the Q ships) commanded by Lieutenant William Edward Sanders (who received a Victoria Cross for the action). HMS Prize was damaged by shellfire. After the 'panic party' had taken to the boats and the ship appeared to be sinking, the U-boat approached to within 80 yards of her port quarter, whereupon the White Ensign was hoisted and the Prize opened fire.

Within a few minutes the submarine was on fire and her bows rose in the air, whilst the Prize was further damaged. The U-boat disappeared from sight, and was believed to have been sunk by the crew of the Prize and by several of the German crew (including her captain) who had been blown or jumped into the sea.

Amazingly, neither of the crippled ships had sunk, with the Prize being towed in flames back to Kinsale, while the U-93 struggled back to the Sylt nine days later after a dramatic escape effort through the British mine and destroyer barrages off Dover.

U 93 after repairs operated in the English channel. She was lost after 15 January 1918 of unknown reasons.[2]
