Meanwhile, late in the afternoon of August 29, 1914, the British retirement began afresh, and 10,000 French troops also withdrew from the Somme, blowing up the bridges as they went. Everywhere along the roads were crowds of country folk and villagers with wagons and carts piled high with household goods or carrying aged persons and children, all in panic flight before the dreaded invaders, fleeing for refuge in Paris. At various places these stricken multitudes joined the army ambulances, taking the shortest routes. Rumors of the coming of the uhlans ran along the straggling lines with tales of the grievous havoc and ruin which these horsemen, vanguards of the German columns, had wrought in the land. Hardly had the retirement begun, when a body of uhlans entered Amiens and demanded from the mayor the surrender of the town. This was formally given, and the civilians were ordered, on pain of death, not to create the slightest disturbance and not to take part in any action, overt or covert, against the soldiery. Afterward, cavalry, infantry, and artillery took possession of the town on August 30, 1914. On the same day a German aeroplane dropped bombs on Paris. While retiring from the thickly wooded country south of Compiegne, the British First Cavalry Brigade were surprised while dismounted and at breakfast in the early morning of September 1, 1914. Moving figures on the distant skyline first attracted the attention of those who had field glasses, but in the dim light their identity was not at first revealed. Suddenly all doubt was resolved by a rain of shells on the camp. Many men and a large number of horses were killed. At once the order "Action front!" rang out, and the remaining horses, five to a man, were hurried to cover in the rear, while on the left a battery of horse artillery went into instant action. The German attack was pressed hard, and the battery was momentarily lost until some detachments from the British Third Corps, with the guns of the artillery brigade, galloped up to its support. Then they not only recovered their own guns, but also succeeded in capturing twelve of the enemy's. On the eventful day of September 3, 1914, the British forces reached a position south of the Marne between Lagny and Signy-Signets. They had defended the passage of the river against the German armies as long as possible, and had destroyed bridges in the path of the pursuers. Next, at General Joffre's request, they retired some twelve miles farther southward with a view to taking a position behind the Seine. In the meantime the Germans had built pontoon bridges across the Marne, and were threatening the Allies all along the line of the British forces and the Fifth and Ninth French Armies. Consequently several outpost actions took place.
