Source-derived summary

SM U-8 was one of 329 U-boatss which served in the Imperial German Navy during World War I.

A Type U 5 submarine, she was built at Germaniawerft in Kiel between 1909 and 1911. The boat was launched on 14 March 1911 and commissioned into the Navy on 18 June. The boat was scuttled in the English Channel in March 1915.

Service history

At the beginning of World War I, U-8 was commanded by Kapitänleutnant Konrad Gansser. In August 1914 she took part in the first U-boat operation of the war, sailing from Heligoland in a coordinated attack on the Royal Navy base at Scapa Flow.

Kapitänleutnant Alfred Stoß took over the boat on 1 September 1914, with Gansser moving to command U-33. During February 1915 she sank five British steamers in the English Channel. On 4 March, however, U-8 became trapped in anti-submarine nets in the Channel and was forced to surface. After coming under gunfire from HMS Gurkha and HMS Maori, the crew scuttled the boat at position 50°56′N 01°16′E. The crew were taken prisoner.

In June 2015 the submarine's propeller, which had been illegally removed from the wreck, was recovered and presented to the German Navy.

Editorial analysis

Why this record matters

“SM U-8” is worth following because a concise public description often conceals a longer documentary argument. Here, Type and submarine provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Feb 20, 2026. The linked authority identifier is Q2207366. Authority coordinates are 50.934, 1.256. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
