11/29/1914 by Frederick T. Richards (1864-1921)
Referencing the comparatively small size of the United States military in 1914, this cartoon shows Uncle Sam standing inactive while the much larger armies of Europe engage in the start of World War One. The U.S. remained neutral throughout much of the war and by the time they entered on the side of the Allies in 1917, the army numbered 200,000. Since this was still a small number compared to the other armies fighting, the U.S. encouraged enlistment and instituted a draft. By the end of the war over 4.7 million Americans would have served.
