'''SM ''U-19''''' was a [[German Empire|German]] [[Type U 19 submarine|Type U-19]] [[U-boat]] built for the [[Imperial German Navy]]. Her construction was ordered on 25 November 1910, and her keel was [[Keel laying|laid down]] on 20 October 1911, at the [[Kaiserliche Werft Danzig]]. She was [[Ceremonial ship launching|launched]] on 10 October 1912, and [[ship commissioning|commissioned]] into the Imperial German Navy on 6 July 1913.

==Service==
From 1 August 1914, to 15 March 1916, ''U-19'' was commanded by [[Constantin Kolbe]]. During this period she had the unfortunate distinction of becoming the first U-boat casualty of [[World War I]] when she was rammed by {{HMS|Badger|1911|6}} on 24 October 1914.<ref name= "Preston p. 29">{{harvnb|Preston|1977|p=29}}</ref> Her hull was badly damaged, but she survived and was repaired.

On 22 January 1915 the ''[[SS Durward (1895)|Durward]]'' was near the [[Meuse|Maas]] [[Lightvessel|lightship]] when they saw ''U-19'' on the surface. They tried to escape, but as they could only manage 12 knots they were unable to do so. The mate of ''Durward'', who was later interviewed by the ''Daily Mail'' special correspondent in Rotterdam<ref>{{Cite web|url=http://www.britishnewspaperarchive.co.uk/viewer/bl/0000452/19150123/149/0006 |title=Register |access-date=29 June 2023 |url-access=subscription |via=[[British Newspaper Archive]]}}</ref> related how the second officer, who spoke excellent English, had ordered them to lower a boat and come to talk to them. The captain and crew were given ten minutes to leave the ship. The mate asked the second officer whether he could return to the ship to collect his clothes. He replied "Sorry, old man, it can't be done. I am in the mercantile marine myself, having been in the North German Lloyd service but now I am doing a bit for my country." The commander of the U-boat towed the lifeboat to within 100 yards of the Maas lightship, even stopping at one stage to repair the tow when it parted, after which the crew of ''Durward'' said goodbye to the submarine and rowed to the lightship.

Kolbe was relieved by [[Raimund Weisbach]], who had previously served as torpedo officer on {{SMU|U-20|Germany|2}} and had (on [[Kapitänleutnant]] [[Walther Schwieger]]'s orders) launched the torpedo that sank {{RMS|Lusitania}}. During his brief command, Weisbach carried out an unusual mission: he delivered the revolutionary [[Roger Casement]] and two other agents to [[Banna Strand]] in [[Ireland]] in hopes that they would foment an uprising that would distract the [[United Kingdom of Great Britain and Ireland]] from [[World War I]].

Weisbach was relieved on 11 August 1916, by [[Johannes Spiess]], who was relieved in turn on 1 June 1917, by Heinrich Koch. Koch turned the boat over on 25 October 1917, to [[Hans Albrecht Liebeskind]], who commanded for less than a month before being relieved on 17 November 1917, by Spiess again. On 1 June 1918, Liebeskind took over again and commanded ''U-19'' until the end of the war.

''U-19'' conducted 12 patrols, sinking 58 ships totalling 99,182 combined tons, including ''Santa Maria'' (5,383 GRT) off [[Lough Swilly]] on 25 February 1918, ''Tiberia'' (4,880 GRT) off Black Head near [[Larne]] on 26 February 1918, and {{HMS|Calgarian|1913|6}} (12,515 GRT) off [[Rathlin Island]] on 1 March 1918.

==Fate==
[[File:U-19 gun Ward Park Bangor right view geograph.org.uk 646194 8c3d0bd1-by-Ross.jpg|thumb|left|{{center|U-19's gun today}}]]
On 11 November 1918, ''U-19'' was surrendered to the British, and was broken up at [[Blyth, Northumberland|Blyth]] sometime in 1919 or 1920.

The main gun of ''U19'' was donated to the people of [[Bangor, County Down|Bangor, Co. Down]] and today sits near the War Memorial in the town's [[Ward Park]]. It was donated by the [[British Admiralty|Admiralty]] in recognition of the valorous conduct of Commander The Hon. [[Edward Bingham]] whilst on board {{HMS|Nestor|1915|6}} while fighting in the [[Battle of Jutland]] in July 1916, for which he received the [[Victoria Cross]].
