<h3 /><h3>Further explanation</h3>
During the year 1917, the underwater battles of the First World War took place most intense in the Atlantic Ocean. Since the German navy, Kaiserliche Marine was much less powerful than the British Navy, Royal Navy, the Germans had to use submarines to be invisible and to be able to sink allied ships. The problem with this tactic was that by attacking underwater, it was not possible to see which country owned the boats attacked. That's why in May 1915, the Germans sank a British ocean liner, the Lusitania, and killed 123 Americans.
The German armies had to suspend their submarine attacks for two years to prevent the United States from declaring war on them. However, as they began to suffer some defeat and also because the war lasted too long, their submarines began firing again from January 1917. This decision pushed the United States declared war on Germany, and the year 1917 was a year of total war in the Atlantic ocean.
During the World war I, the 345 German U-Boote had sunk 6394 merchant ships and nearly 100 warships. Despite their defeat in this global conflict, the Germans have been effective in this type of attack.
