The Battle of the Somme referred to above was intended to relieve the terrible pressure of the Germans on the French forts at Verdun. The German Crown Prince had attacked these in July, 1916, determined to break through at whatever cost. But the soul of France rose to the occasion and declared, "They shall not pass!" The Battle of Verdun lasted from July until December, 1916. The Germans lost half a million men, _but they did not pass_. Before many months every vantage point which the Germans had won was back in French hands. In 1917, the French pushed the Germans back between Rheims and Soissons to the Ailette River, where they remained until the Second Battle of the Marne, July, 1918. Little of importance happened during the winter of 1917 and 1918, and Germany, with Russia out of the way, prepared to deliver a final blow and win the war, before American troops should arrive in force. The Germans, with large numbers of troops from the eastern front, were so confident, that great fear was felt among the Allies that America would be too late. The German plan as it unfolded itself was to attack, wave after wave, with tremendous numbers of men; to use great quantities of a new and more terrible gas; to pay no attention to losses, but to break through where the French and English lines joined; then to push the French south towards Paris and the English north towards the sea. They expected to take Amiens, forty miles from the mouth of the Somme, and to push down the river to the sea. With the broad river between them and the French, a small force could keep the French from crossing, while the great German army captured or destroyed the British, who would be hemmed in by the sea. The attack was launched on March 21 over a front of fifty miles and it nearly succeeded. It brought the Germans to within six miles of Amiens, which would have been captured if the English on Vimy Ridge had not prevented them by holding the German line from advancing. The Germans waited a month, planning an attack which should capture Vimy Ridge and prepare the way for the capture of Amiens. In this they were unsuccessful. Not being able to divide the armies of the French and English or to take the Channel ports, they turned in May toward Paris. They attacked in tremendous force between Rheims and Soissons and pushed forward thirty-two miles to the Marne. On July 15 they launched another great offensive over a front of fifty miles from east of Rheims to west of Château-Thierry. They crossed the Marne and were making some progress when, on July 18, the French and Americans struck them on the flank between Soissons and Château-Thierry. The Germans were forced to retreat, having lost 220,000 men, hundreds of guns, and vast stores.
