The Romance of Golden Star by George Griffith

Now this story of mine is nearly done, for there are but few things left for me to tell. It is not for me to write of all the battles that we fought after the City of the Sun and the region about it fell into our hands, for to do that is a task better fitted to the hands of him who led my ever-growing hosts to victory after victory until the whole land that had been my fathers' was mine from north to south and from the great rivers of the east to the Sea of the Setting Sun, which you now call the Pacific Ocean.

It is enough for me to say that I used my gold without stint, and that it did all and more than the work I had been told it would do. As we marched southward and westward to the sea, army after army left those who were fighting between themselves for the ruins of the land and, having no real quarrel of their own, ranged themselves under the Rainbow Banner and fought with me for freedom and the ancient faith of their long-dead fathers, and how city after city welcomed me as I came to give it peace and wealth instead of strife and misery.
