It was now the Americans' turn to attack. The marines, pushing forward on the morning of June 6, penetrated to a depth of over two miles on a front of two and a half miles, and occupied all the important high ground northwest of Château-Thierry. The French co-operated to the left of the Americans. The Germans were so hard pressed by the Americans that in three days it was necessary to bring up three new divisions of the best German troops.
The Americans continued to advance, pushing forward to a line which lay through Les Mares Farm, just north of the village of Lucy le Bocage, and on through the outskirts of the town of Triangle. This line included strong positions in Bussiares Wood, the crossroads south of Torcy, and the southern edge of Belleau Wood. During the night of June 6 the fighting raged with great fierceness for five hours. The Americans captured Bouresches and Torcy. Further fighting on June 7 extended the American line over a front of about six miles to a depth of nearly two and a half miles. While the losses of the Americans were necessarily heavy, the German dead were piled three deep in places.
The importance of the operations of the Americans on the Marne sector was evident from the fact that the day before they arrived on the front and began fighting, the Germans advanced about six miles. While the Americans advanced their line, the French completed the capture of Vilny, Veuilly-la-Poterie, and the heights southeast of Hautevesnes.
BELLEAU WOOD ENGAGEMENT
Following the capture of Bouresches came the fierce fighting for the possession of Belleau Wood to the north. This wooded hill was a stronghold of German infantry and machine gunners, and the only way to attack it was by advancing to the other side. The American infantry had the assistance of the artillery in clearing the wooded heights, and in the biggest artillery engagement in which the Americans had yet been engaged more than 5,000 high explosive and gas shells were thrown into the German machine gun nests in the woods. Meanwhile German attacks against Hill 204, west of Château-Thierry and commanding the town, were repulsed.
The United States marines attacked again on the morning of June 10 and penetrated the German lines for about two-thirds of a mile on a 600-yard front in Belleau Wood, with the result that the Germans were driven from all but the northern fringe of the wood. On June 11 the wood was captured and 300 prisoners were taken.
FIRST FIELD ARMY
The War Department received reports on May 21 which showed that the first of the field armies had been organized and was in service in France. The army, composed of two army corps, each made up of one regular army, one National Guard, and one National Army division, was placed under the temporary command of Major Gen. Hunter Liggett, the senior Major General then in foreign service. General Liggett was selected to command the first army corps organized in France, and this corps, with that temporarily commanded by Major Gen. Charles T. Menoher, made up the first field army, the total strength of which was almost 200,000 men. By June 14 the American forces in France had become so numerous that General Foch had informed General Pershing that it was desirable to maintain them as purely American units. This fact was communicated to the House Military Affairs Committee by the War Council at Washington. In accordance with this policy two full American divisions were engaged in the fighting in the Château-Thierry sector. The Secretary of War told the committee that General Foch was gradually decreasing the number of Americans brigaded with the French and British, and thereby increasing the American unit.
Official announcements made at Washington showed that approximately half a million soldiers had landed in France since the German drive began on March 21, 1918, and that Americans held no more than fifty miles of the whole western front. One element of Pershing's mobile forces, by direction of General Foch, guarded the way at the apex of the whole German wedge near Montdidier. Cantigny, which was captured by these forces, was very close to the point of maximum penetration achieved by the enemy after nearly three months of desperate fighting.
The total casualties sustained by the American Expeditionary Forces from the beginning of American participation in the war up to June 17, 1918, is shown in the following figures issued by the War Department at Washington:
