There were many factors in the war that contributed to the Allied victory in 1918, one of them was the war at sea. It is important to compare the effectiveness of maritime warfare with the other factors that influenced the Allied victory in World War I; these factors are American entry into the war, land warfare, air warfare, and weapons development. I will try to evaluate the extent to which maritime warfare was the most important reason for the Allied victory, because I believe it was the most significant factor that helped the Allies win the war in 1918. The naval tactics used by both sides have played a very significant role in the First World War. The British navy, which was stronger than the German one, did everything to maintain control of the sea, blockading the German fleets in their ports, while Germany isolated parts of the British fleet to weaken them. The only major naval battle between 1914 and 1918 took place in May 1916: the Battle of Jutland, which is often considered a British victory because after the battle, the German fleet "escaped" and remained in port for the rest of 1918 . the war. Despite this, Britain suffered the loss of approximately three times as many men and lost more ships than Germany. However, Britain was much more successful in using the blockades to its advantage, preventing supplies from reaching Germany, weakening the country's army and civilians. The convoy systems were also effective in ensuring that Germany was unable to react to this action. The war fought at sea was described by John Laffin in "Butchers and Buddlers of the First World War" as "the most decisive role in winning". the war." He argued that he had 'impo...... middle of paper...... Allies. In 1933, Prime Minister Lloyd George wrote in his war memoirs: "The conclusion is inevitable that Germany and his allies were defeated on the field". Even so, in contradiction to the Prime Minister, I believe that without a Germany already unstable due to lack of resources and food, the land war would not have been so effective as to push Germany to surrender. evidence I used, I believe drew the conclusion that each factor was important to winning the war and without each of them the Allies probably would not have won. However, in my researched opinion, the war at sea was the most important reason for which the Allies won the war, followed by the entry of the United States into the war and the land war respectively, because each factor would not have been as effective had it been for the devastation of Germany by the naval tactics used by the British.
