Battle off Texel The Battle off Texel , also known as the Action off Texel or the Action of 17 October 1914 , was a naval battle off the coast of the Dutch island of Texel during the First World War where a British squadron consisting of one light cruiser and four destroyer s on a routine patrol encountered the remnants of the German 7th Half Flotilla of torpedo boat s , which was " en route " to the British coast on a mission to lay minefield s . The British forces attacked and sank the entire German flotilla of four torpedo boats . Heavily outgunned , the German force attempted to flee and then fought a desperate and ineffective action against the British force . The battle resulted in the loss of an entire German torpedo boat squadron , and prevented the mining of heavily trafficked shipping lane s , such as the mouth of the Thames River . The British in exchange took only light casualties and little damage to their vessels . The outcome of the battle also greatly influenced the tactics and deployments of the remaining German torpedo boat flotillas in the North Sea area , as the loss greatly shook the faith of the commanders in the effectiveness of the force . Background . After the opening naval Battle of Heligoland Bight the German High Seas Fleet was ordered to avoid confrontations with larger opposing forces in an effort to avoid costly and demoralizing reverses . Thus outside of occasional German raid s , the North Sea became dominated by the Royal Navy which regularly patrolled the area . Despite the lack of action by German capital ship s , light forces still operated regularly in North Sea . At 13 : 50 on 17 October 1914 , one such routine patrol by the 3rd Destroyer Flotilla Harwich Force consisting of the light cruiser under Captain Cecil Fox and four " Laforey " - class destroyer s , , , , and , was cruising off the coast of the island of Texel when they encountered a waiting German squadron of torpedo boat s consisting of the remaining vessels of the 7th Half Flotilla under Georg Thiele : , , , and . " S119 " was the lead ship of the torpedo boat flotilla and was personally commanded by " Korvettenkapitän " Thiele himself . The German ships made no attempt to challenge or threaten the approaching British ships nor did they at first attempt to flee the scene , and it was assumed by the British that they were waiting for more German vessels to arrive and had mistaken the British ships for friendly vessels . In reality , the German flotilla had been sent out of Ems on a mission to mine the southern coast of Britain including the mouth of the Thames and had been intercepted before reaching its targeted area of operations . The British squadron heavily outgunned the German 7th Half Flotilla . The British Commander , Captain Cecil Fox ' s vessel " Undaunted " — an " Arethusa " - class light cruiser — was armed with two BL 6 inch Mk XII naval gun s and seven QF 4 inch Mk V naval gun s , all in single mount s and nearly all without gun shield s . " Undaunted " at the time of the engagement was also experimentally armed with an additional pair of 2 - pounder anti - aircraft gun s , something most of her class lacked . In addition to her guns , the cruiser was also armed with eight torpedo tubes and at best speed could make . The four British " Laforey " - class destroyer s were much less powerful vessels in comparison to the cruiser being only armed with two torpedo tube s , three 4 - inch gun s and a singe 2 - pounder gun . The destroyers were slightly faster than the cruiser and could make about at full power . The German vessels were entirely inferior to the British in many areas . Not only was the 7th Half Flotilla outnumbered and antiquated , but it was also lightly armed . The four boats were of the aging " Großes Torpedoboot 1898 " class and had been completed in 1904 . In terms of speed , the German boats were nearly equal to the British at . Each of the German vessels was armed with three guns , significantly fewer than the British destroyers . These weapons were also of shorter range and throwing weight than the British guns . The biggest danger to the British squadron was the torpedo tubes carried by the German boats , as each boat carried three torpedo tubes with five torpedoes per boat . Battle . Upon closer approach , the German vessels realized the approaching vessels were British and began to scatter and flee while " Undaunted " — which was closer to the Germans than the destroyers — opened fire upon the nearest torpedo boat . This German vessel managed to dodge the incoming fire from " Undaunted " by changing course but by doing so lost enough speed that the British force caught up with them . In an attempt to protect " Undaunted " from torpedo attack and to destroy the Germans as quickly as possible , Captain Fox — the squadron commander aboard " Undaunted " — gave orders for the squadron to split up into two divisions . " Lance " and " Lennox " proceeded to chase " S115 " and " S119 " while " Legion " and " Loyal " went after " S117 " and " S118 " . Combined fire from " Legion " , " Loyal " , and " Undaunted " damaged " S118 " so badly that the torpedo boat ' s entire bridge was blown off the deck of the vessel , sinking her at 15 : 17 . Meanwhile , HMS " Lance " and " Lennox " engaged " S115 " disabling her steering gear and causing the German vessel to circle . " Lennox " s fire was so effective at this point that , as had occurred with " S118 " , the bridge of " S115 " was completely destroyed . Despite the damage the German torpedo - boat still did not strike her colours and vainly continued the action . The two centre - most boats in the German flotilla — " S117 " and the flotilla leader " S119 " — then made an attempt at engaging " Undaunted " with torpedoes . Despite the torpedo attack , " Undaunted " was able to outmaneuver the German boats and remained unscathed . " Legion " and " Loyal " who had been finishing off " S118 " came to " Undaunted " s aid and engaged " Undaunted " s two attackers . " Legion " assaulted " S117 " , but the torpedo boat fired her last three torpedoes at the destroyer and afterword continued to resist with her guns . This vain attempt failed , and " Legion " pulverized " S117 " damaging her steering mechanism which forced her to circle before she was finally sunk at 15 : 30 . At the same time " Legion " was battling " S117 " , " Lance " and " Lennox " had damaged " S115 " to the point where only one of the destroyers was still needed to counter the vessel . " Lance " soon left the battle with " S115 " to join " Loyal " in pummeling " S119 " with lyddite shells . " S119 " managed to get off a successful torpedo run against " Lance " , hitting the destroyer amidships , but the torpedo failed to detonate . " S119 " was then sunk at 15 : 35 by combined gunfire from " Lance " and " Loyal " , taking the German flotilla commander down with it . The last remaining torpedo boat " S115 " continued to stay afloat despite constant attacks from " Lennox " . The British destroyer eventually boarded the vessel finding her a complete wreck with only one German onboard who happily surrender ed . Thirty other Germans were eventually plucked from the sea and captured by the British vessels . The action finally ended at 16 : 30 with gunfire from " Undaunted " finishing off the abandoned hulk of " S115 " with heavy gunfire . Aftermath . The German Seventh Half Flotilla was completely annihilated by Harwich force , with all four of its remaining vessels sunk and over two hundred sailors killed including the commanding officer . Despite the odds no German vessel struck her colours and the entire Flotilla went down fighting to the end . The British casualties were extremely light in comparison with only four men wounded and superficial damage to three of the destroyers . " Legion " took one shell hit and had one man wounded by machine gun fire . " Loyal " took two shell hits and had three or four men wounded as a result . " Lance " took some superficial machine gun damage and the other two vessels were unscathed . Thirty - one surviving German sailors were taken out of the water and off the sinking hulks and made prisoner s , but one captured officer soon after died of the wounds he had received during the action . Two other German sailors were later plucked from the water by a neutral vessel . The battle was seen as a great boost of morale for the British at the time , as two days previous to the action off Texel they had suffered the loss of the cruiser due to a U - boat attack . The effect on British morale the battle had is reflected in its fictionalized and nationalistic inclusion in the 1915 dime novel " The Boy Allies Under Two Flags " , by Robert L . Drake . Some controversy arose in Germany from the battle because the German hospital ship , which had been sent out to rescue survivors from the sunken boats , was seized by the British for violating the Hague Convention ' s rules on the use of hospital ship s . Although the boats of the sunken flotilla were older and some casualties were expected , the loss of an entire squadron of torpedo boats changed the tactics of the German forces displaced in the English Channel and along the coast of Flanders drastically . As a direct result , there were very few further sorties into the Channel and the torpedo boat force was delegated to coastal patrol and rescuing downed pilots for fear of similar losses . An unexpected boon for the British came as a result of the action , when on 30 November a British fishing trawler working the area pulled up a sealed chest that had been thrown off " S119 " by Captain Thiele during the action so as to avoid its capture . The chest contained a German codebook used by the German light forces stationed on the coast , allowing the British to decipher intercepted German communications long after the action had ended .
