It was evident everywhere in the battle areas that the Germans were retiring in great haste, for as the Allies drove forward they found on the battle ground abandoned guns, stores, and even artillery maps and military documents. Allied observers reported streams of enemy transports and men hurrying eastward in full retreat. A joyous spirit pervaded the ranks of the Allies as they moved victoriously forward, their cavalry rounding up villages, while tanks and armored cars overran the country clearing a way for the advance of the troops, or destroying the enemy transports. The performance of one tank is especially worthy of record, since it shot up a German corps headquarters. Running into an enemy-held town, where the German corps headquarters staff stationed there was having luncheon, the tank opened fire through the windows, killing a number of Germans and wounding others, while a few managed to make a hurried escape. Inside the German lines a group of armored cars halted a German supply column and destroyed it. At Framerville a train loaded with Germans was attacked by a group of cars and finally set on fire. All along the line enemy snipers were active, and isolated gun billets were a source of trouble, but these were silenced one by one as the Allies swept on. The Germans tried to destroy all their ammunition dumps and stores in their hasty flight, but had not time to make a complete job of it, and consequently were forced to abandon vast quantities of military supplies, most of which the French and British found immediate use for. The towns captured from the Germans were inhospitable places for the most part. The enemy had tried to destroy everything before the retirement, but the Allies' advance was so rapid that all the houses could not be dynamited. In and around most of the towns were found small holes covered with curved iron slabs where the German gunners had lived before they were killed or forced to run for their lives. The result of the Allied advance had an important effect on the strategical situation, for the Germans were now in an uncomfortable salient with only one line of railway to supply them, and that was under fire of the Allied guns. The advance had also freed for the use of the Allies the main Paris-Amiens railway. Previous to the German retirement this line was under easy range of their guns and the Allies were unable to use it freely.
