When the Admiral was imprisoned on false traitor charges, he was replaced with a incompetent bootlicker who was over confident in the turtle ships and thought that was the reason for the string of victories, not Yi's amazing planning and direction. Because of this, in the following battles without Yi, all the turtle ships and the majority of the Korean fleet was destroyed. Because of this, Yi was able to be reinstated as Admiral despite not being completely cleared from charges.
This battle is the last battle of the entire war, where Yi had only 12 war ships and several dozen fishing ships to use against nearly a hundred Japanese ships.
