Robert Farley finds an interesting example from the First World War:
Viribus Unitis was the first dreadnought of the Austro-Hungarian Navy. In October 1918, when it was becoming clear that the Central Powers would not prevail in the war, and that their navies would become subject to confiscation by the Allies, Emperor Karl I of Austria decided to turn over Viribus Unitis to the newly created Council of Slovenes, Croats, and Serbs that would soon occupy formerly Austrian territories on the Adriatic. Italy, however, had designs on some of the Austrian territory that might be turned over to the Croats, and didn't like the idea of 3 modern dreadnoughts being in the possession of the Austrian successor state. Although the SCS declared that it was no longer at war with the Allies, this declaration was not immediately recognized. Accordingly, Italy dispatched a pair of young men named Raffaele--one a Lieutenant Paolucci, and the other a Major Rossetti--to infiltrate Pula Harbor on a modified torpedo and attach a bomb to the dreadnought's hull. This the Raffaeles succeeded in doing, but they were captured while escaping, and brought on board the Viribus Unitis.
The Italians told the ship's commander that there was a bomb affixed to the hull, but they would not say where. The commander decided not to torture the men, but neither did he evacuate the ship, deciding instead to try and minimize the damage. The result was that the ship sank with some 300 men on board. I'm not sure that this informs the current debate in any substantive way, but it's a great story.
