There were many equally important reasons why the stalemate on the western front was finally broken: New technology like the tankThe American entry into the war

The tanks gave the Germans a fright at first; however it was later in the war that the tanks showed there worth as a weapon. Another big development in weapons was gas. However only 3,000 British troops died in the war from gas. Gas masks were invented very quickly so the gas was seen as a quite ineffective weapon, apart from the fact that they created terror amongst the troops.

Other weapons appeared such as the grenade, which was very effective at killing troops in a trench. They were more a close range weapon which meant that they had very few uses when you are at your own trench with not an enemy in sight..

Hopes were lifted when on the 6th of April 1917 America entered the war on the side of the allies. Soon after the Americans joined the Russian Revolution happened and Russia pulled out of the war. The Americans joining equalled fresh troops and resources. This was thought to put the stale mate in the allies favour. However it would take the Americans about a year too mobilise as they have a long way to go and as they like the British only really have a Navy as they live on an island. As the Russians pulled out of the war this meant he German’s could take all of there army from the West side and put it on the East side making the force larger.  

Britain’s war plan of blocking the German ports had paid off. Germany was starving. The British were stopping vital resources such as food, weapons and medication getting to Germany. With out food Germany would have no choice but to surrender. So the Germans had to throw all there men into the Allies and win the war before Germany starved. Germany launched a huge offensive in March 1918. The German’s absolutely smashed stalemate. Ludendorff used new tactics like the Storm troopers which were elite soldiers, in small groups. There mission was to go across no-man’s land at night in the heavy fog undetected and break through the allied barbed wire then Carrie on to the other side of no man’s land. Then the allied troops would be surrounded and then slaughtered by gun fire.    

This tactic was a great success as German almost got to France. However this is were the new tactics and weapons like the air force and tanks really helped. With the Germans no longer hiding in there trenches the tanks and other new weapons forced the German’s in October in to a retreat. At last the war was almost over and the allies had saved there land from German rule.

The event are all inter-connected as if it was not for the British blockading the German ports. Germany would feel no need to rush and the German offensive would maybe not have happened and we may have been under German rule today. If it was not for the new technology we maybe would not have stopped the German offensive and they might have broken through to Paris which would have resulted the Germans winning the war and the American entry useless. If it was not for the Americans joining the allies the morale of the allies would have been very low. Also with Russia leaving the war the Germans would have had more numbers.
