Allied forces continued their victorious sweep northward on August 3, 1918, capturing practically the entire Aisne-Vesle front between Soissons and Rheims, which marked an advance of six miles at some points, while more than fifty villages recently held by the enemy were recovered.
The Allies' advance was on a front of thirty miles, and before the close of the day they held the southern banks of the Aisne and the Vesle from Soissons to the important town of Fismes, where American troops occupied positions on the outskirts.
East of Fismes the Allies were on a line north of Courville, Brancourt, Courcelles, and Champigny, towns in close proximity to the Vesle River, while cavalry patrols were operating along the Soissons-Rheims railroad which follows the course of the stream.
To the north British forces operating in the Albert sector were making substantial gains, forcing the Germans to retreat to the east bank of the Ancre River on a frontage of between seven and eight miles and at some places over a mile in depth. This was followed by the capture of Dernancourt by the British, while their patrols entered the outskirts of Albert.
The capture of Fismes, the great ammunition and supply depot, on August 4, 1918, was the most important victory won by the Allies on that date. The brilliant performance of the American troops on this occasion received high praise.
Northwest of Rheims the Allies had pushed forward to the village of La Neuvillette, about two miles north of the Vesle. East of Fismes at several points in the neighborhood of Champigny bodies of French troops had crossed the Vesle River, and the result of these advances was the retreat of the Germans from the southern bank.
The inability of the enemy to make a determined stand on an established line was due to the constant pounding which Foch maintained and a constant pressure that never relaxed. The big salient that had loomed so formidable a fortnight before was now almost wiped out. With British and French troops in one corner of it, Americans in the center, and British, French, and Italians in the other corner, the Germans never had an opportunity, harassed as they were on all sides, to establish themselves in positions to check the Allies' advance. So they chose the better part of valor and retreated, leaving a trail of burning villages behind them. But their flight was too hurried for them to destroy all their stores, and goods to the value of millions of dollars fell into the hands of the Allies.
The Vesle River, flooded by recent rains, hampered the retreat of the German rear guards, who, unable to cross the stream, were forced to fight for their lives. Most of them were killed and the rest were made prisoners.
On August 5, 1918, the Germans attempted to make some kind of stand on the Vesle, where their heavy guns were busy shelling the Allies' lines. In spite of this resistance French patrols succeeded in crossing the river at several points between Sermoise, east of Soissons and Fismes, and between Fismes and Muizon. The Germans on the north bank were well supplied with machine guns and bomb throwers, while their aviators, using machine guns, wrought considerable destruction among the French troops. Between Muizon and Rheims, where the French were firmly established on the south bank of the river, there was hard fighting, but the Germans were unable to dislodge the French from their positions.
In the morning of August 7, 1918, Field Marshal Haig delivered a heavy blow at the armies of Prince Rupprecht of Bavaria on the southern side of the Lys salient. The British attack was launched on the front of about five miles, advancing their whole line to a depth of a thousand yards. To the south on the front east of Amiens on the Bray-Corbie road British troops recaptured positions which the Germans had occupied on the previous day.
