On June 19, 1911 there was a near-mutiny on the armored cruiser Georgios Averof, while she was undergoing repairs after running aground at Spithead (near Portsmouth, UK). Wikipedia alleges the reason was the Greek sailors unfamiliarity with blue cheese (that their English hosts presumably served them), without providing any sources. The Greek version of the article doesn't provide a reason at all, and a random Greek blog I've found alleges the reason was the fact that she run aground. In any case, the near-mutiny lead to the immediate replacement of her Captain by the more experienced and capable Pavlos Kountouriotis.
The blue cheese story sounds plausible, and so does the alternative explanation that the crew didn't enjoy having a Captain that run the ship aground on her maiden voyage and only three days after he took command. In fact, both stories may very well be true, but I can't seem to be able to find any reliable sources for what actually happened. My searches are hindered by the fact that there was another mutiny on the Averof, in April, 1941. Although Wikipedia surprisingly only mentions the event in passing, Greek sources emphasize it, to the point that every possible combination of search terms I could think of results in documents about the 1941 event.
