On the 28th Franco-British troops proved the assault in the north to be abortive by quickly re-establishing their lines east of Dickebusch Lake and capturing a few prisoners. On the main field of battle in the south the Franco-British right deployed to the east covering the Brouillet-Savigny-Thillois line protecting Rheims. On the west they did the same, but with more elasticity, while the centre continued to give. On the 29th the acute angle of the German penetration, with its vertex covering Fismes, suddenly sprung to the shape of a bow. The line still held covering the Cathedral City, but on the west the defenders of Soissons were killing their last Germans, and in the south Savigny on the Ardre had been reached. At Savigny the line of advance was diverted westward until it embraced Fère-en-Tardennois and Vezilly. And still the retreating but unbroken Allies were deploying east and west as its pressure increased, or were taken prisoner when retreat became impossible. On the 30th the enemy attempted to broaden his front northwest of Rheims and failed, but he succeeded in obliterating the salient south of Noyon, from the Oise Canal to Soissons, and on the 31st by an advance from a twenty-five-mile curved front he reached the Marne between Château-Thierry and Dormans on a contracted six-mile front. Here he met on the south bank the prepared defenses, and has been kept on the north bank ever since. AMERICAN MARINES In the enemy's attempts to broaden his front on the Marne salient, June 1 and 2, he managed to rectify the eastern side by reaching Sarcy and Olizy and by working along up the Marne a couple of miles east of Dormans. He also measurably consolidated his positions between the Oise Canal and Soissons, and south of the latter stretched the line into a segment with a five mile vertical as far south as, but not including, Château-Thierry on the Marne. This swing to the westward appears to have been a deliberate attempt to force Foch to meet shock with shock by throwing in his reserves, as the German advance had reached a point only forty miles from Paris.
