SM U-26 was one of the 329 submarines serving in the Imperial German Navy (Kaiserliche Marine) in World War I.

U-26 was engaged in the Naval warfare of World War I in the Baltic Sea. On 11 October 1914, she sank the cruiser Pallada, inflicting the first loss of the war on the Russian Navy.

Fate[edit]

The boat did not return from sea in August 1915, and is assumed to have struck a mine off the coast of Finland, being lost with its entire crew of 30.

Wreck discovered[edit]

The boat was found in the western Gulf of Finland as reported by the Finnish newspaper Helsingin Sanomat in May 2014.[2][3]
