International News Service reports on battles in northern France as U.S. assembles troops and supplies to join the fight.
April 21, 1917: Heavy fighting continued along the Siegfried line, or German defensive positions in northern France, during World War I. The Germans made a "determined stand" in the face of French assaults and mounted a series of counterattacks. The French reported as many as 200,000 Germans killed or wounded in the fighting, according to the International News Service. In the United States, newly involved in the war, preparations continued to raise and send troops and to stop "any foodstuffs from here reaching the Germans."
