Why turtle-ship commanders are difficult to identify

Can you name commanders of Korean turtle ships?

No reliable list is available in the English-language material; a relative of Yi is a possible commander, but the identification remains uncertain.

The English-language sources used here do not provide a dependable list of individual commanders. One of Yi's nephews may have commanded a turtle ship because that relative appears repeatedly in battle accounts, but the identification remains only a possibility. Repetition in a narrative is not the same as an explicit command record. The available evidence supports a plausible identification rather than an attested roster.
