The disadvantages of the tank was that when the tank was first developed not many people new how to use it and it did not have much effect as none of the men could keep up with the tank so it was always advancing to far ahead of the troops, the tank was almost to effective as it would blast through the enemies lines so quickly the infantry could not keep up. Germany also started inventing the tank so the sides were once again equal.
There were also other new inventions like the new types of gasses for example chlorine and phosgene, there were advantages and disadvantages to using these types of gasses for example the disadvantages were that chlorine could be seen and its effect was immediate. And Phosgene was a terrible gas that was later developed which could not be seen and was not effective immediately causing only mild discomfort to begin with but eventually deadly.
The American entry into the war was an important contributing factor, the Americans joined the war in April 1917 they joined as there were many bad feeling between them and Germany since 1914, they were officially neutral but they were clearly supplying loans and equipment to the allies which made the Germans place a policy of unrestricted submarine welfare against Americans ships which were suspected to be carrying supplies to the allies. Things started to look down for Germany as America had the third largest navy in the world after Britain and Germany; the American government was also willing to lend Britain money so t could buy vital supplies from the U.S.
American troops were poured into France In 1918 at a rate of 250,000 a month. These fresh and enthusiastic troops were important in the successful allied offensive which eventually broke Germanys will to fight on.
The blockading of the German ports was a contributor as this stopped arms and food supplies for entering Germany and also starved Germany of al the raw materials. This built a lot of morale throughout the allies and destroyed germane troop’s moral in the process. The blockading was described as maybe one of the greatest achievements. The effect of the allied blockade on the nutritional levels in Germany worsened after 1916 which increased the civilian mortality, hunger had become a rife. The worse period of the war was the summer of 1918 when sever food shortages coincided with the retreat of the main German armies.
The German offensive 1918 was also an important contributor General Ludendorff was in charge of the great offensive and he planned to break the stalemate. Instead of an ‘over the top’ frontal assault by a wave of troops. He sent small groups of ‘stormtroopers’ to attack all along the western front line. It was a success and the Germans broke through the line and drove the allies back more then 60 kms, and once again the Germany army was in sight of Paris. But the German army became exhausted and could not reach Paris as the allies had fought hard to hole their positions and American troops were now joining them. Now it was the turn of the allies to push the Germans back and the new invented technology helped. The Germans eventually withdrew to the Hindenburg lines.
All of these factors are sole contributors the reason why stalemate was broken on the western front as if American had not joint the war then the German offensive would have succeed even better and the allies may not have been able to push germane back which also need the invention on the new tanks and gas weapons. So I agree with the statement that they are all equally important reasons to why stalemate was finally broken on the Western front.
