The attack, which was the fourth great battle of Ypres, was the biggest effort the Germans had made in the Flanders offensive, the enemy employing thirty fresh battalions of reserves, in addition to the large number of divisions in position at the beginning of the battle. The net result was a tremendous setback for the Germans, who paid an awful price. Next morning the battlefield in front of the defenders' positions was covered with the bodies of gray-uniformed men. AMERICAN TROOPS IN ACTION American units were in action in Picardy, east of Amiens, on April 28, having reinforced the British and French in that sector, to aid in keeping the foe from Amiens and Paris. Their baptism of fire in the direct line of the German offensive made their previous experiences pale into the insignificance of skirmishes. During the various engagements in which they participated in the last days of April and the first week of May they acquitted themselves with great credit. After a preliminary bombardment of two hours, a heavy German attack was launched against the Americans in the afternoon of April 30 in the vicinity of Villers-Bretonneux, and was repulsed with heavy losses to the enemy, who left dead and wounded on the field, while the American losses were reported as "rather severe." There was hand-to-hand fighting all along the line, and the violent struggle lasted for a considerable time before the enemy was finally thrust back, leaving prisoners in the American hands. Their French comrades were full of praise for the marked bravery displayed throughout by the American troops, who were fighting at one of the most difficult points on the whole battle front. U.S. TROOPS BUSHED TO PRANCE As a result of the great German offensive movements and territorial gains in the spring of 1918, there was a tremendous increase in the military activities of the United States, particularly in rushing troops to Europe. After the selection of General Foch as generalissimo of the Allied forces, the American troops in the war zone were brigaded with the French and British all the way from the North Sea to Switzerland, and their numbers steadily increased. In the United States the training of the new National Army, national guards, and officers in the numerous cantonments and training camps was intensified and hurried. As fast as the men were brought into condition they were shipped to France. At first much of the space on the transports was devoted to supplies and materials for the camps and depots in France, but as the situation became critical owing to successful enemy offensives, fewer supplies and more men were sent. Great Britain lent her ships and the number of transports was largely increased, so that each month of 1918 showed a greater movement of troops across the Atlantic.
