And then basically you have World War I. The Great War is what it was called. It was for three or four years, huge trench warfare, hundreds, tens of millions of people dead, something like one-eighth of all French people, men were dead. And basically that war went on for a few years with no end in sight. And then as America got kind of wrapped up into that war, the sinking of the Lusitania, the Germans were using submarines like you wouldn't believe. They had really captured that technology. And they were blowing up ships that were coming from America because America was sending arms to, you know, England, the Allied powers.
