Stalemate stalemate  By September 1914, the war had reached a stalemate, a situation in which neither side is able to gain an advantage. “no man’s land.”  When a French and British force stopped a German advance near Paris, both sides holed up in trenches separated by an empty “no man’s land.” Small gains in land resulted in huge numbers of human casualties.  Both sides continued to add new allies, hoping to gain an advantage. Modern Warfare  Neither soldiers nor officers were prepared for the new, highly efficient killing machines used in WW I.  Machine guns, hand grenades, artillery shells, and poison gas killed thousands of soldiers who left their trenches to attack the enemy.  As morale fell, the lines between soldiers and civilians began to blur.

Some will wish one nation, others another, to succeed in the momentous struggle. I venture, therefore, my fellow countrymen, the United States must be neutral in fact, as well as in name, during these days that are to try men's souls. wilson neutrality1
