To correct it, this famous saying comes from the preface of a book, but it was definitely not said by Napoleon, because when Napoleon died, there was still half a century before the reunification of Germany. Therefore, it should come from the pen of later generations.

The original words may be like this.

It was Caesar who made Rome strong, and it was William I who unified Germany instead of Bismarck. It was Caesar who defeated ancient Greece instead of Alexander.
