warned, turned and made their way home. Even then the Emperor would not give up, but set in motion new plans for the invasion of Japan. This wish was not to be gratified. A year later it became apparent to him that Koryu had been squeezed to the very limit, and the terrible privations of his own troops led him to change his mind. It must have been a bitter hour for him.
The last century of the Koryu dynasty was one swift fall into worse and worse excesses, until the end.
