The actual numeric strength of the Japanese fleet that Admiral Yi fought is unclear; various sources indicate the number of Japanese ships could have been anywhere between 120 and 330 ships, though the low end of this range appears to be a count of actual warships and the high end appears to be referring to the entire Japanese fleet (including roughly 200 supporting non-combatant ships).[2]:312[5] Regardless of the size of the Japanese fleet, all sources indicate that the Japanese ships heavily outnumbered the Korean ships, by at least a ten-to-one ratio.[1]:302 In total 30 Japanese warships were sunk or crippled during the battle.
