19. Document E The German officer knocked at the door…The officer ordered the soldiers to break down the door, which two of them did. The peasant came and asked what they were doing. His hands were tied behind his back, and he was shot at once without a moment’s delay. The wife came out with a little sucking child. One of the Germans took a rifle and struck her a tremendous blow with the butt on the head. Another took his bayonet and fixed it and thrust it through the child. He then put his rifle on his shoulder with the child up on it, its little arms stretched out once or twice. The officers ordered the house to be set on fire…The man, his wife and child were thrown on top. (James Bryce, head of the Committee on Alleged German Atrocities as reported to British Parliament, 1915)

20. Document F We shall fight for the things which we have always carried nearest our hearts,—for democracy, for the right of those who submit to authority to have a voice in their own Governments, for the rights and liberties of small nations, for a universal dominion of right by such a concert of free peoples as shall bring peace and safety to all nations and make the world itself at last free…The world must be made safe for democracy.(President Wilson's war message, April, 1917)

21. Document G

22. Document H To whom does war bring prosperity? Not to the soldier who for the compensation of $16 per month shoulders his musket and goes into the trench, there to shed his blood and to die if necessary; not to the mother who weeps at the death of her brave boy; not to the little children who shiver with cold; nor the millions of mothers and daughters who carry broken hearts to their graves. War brings prosperity to the stock gambler on Wall Street – to those who are already in possession of more wealth than can be enjoyed…Their object in having war and in preparing for war is to make money. The enormous profits of munition manufacturers, stockbrokers, and bond dealers must be still further increased by our entrance into the war. (Senator George Norris, in response to the U.S. declaration of war, April 1917)
