Battle of Manila Bay on May 1, 1898. Montojo was wounded during this battle, as was also one of his two sons who were participating in this battle. United States naval forces under Commodore George Dewey decisively defeated Spain's Pacific fleet, at anchor in Manila Bay, the Philippines. Most of the seven Spanish vessels sank or surrendered. 20th century In the 20th century, the internal combustion engine and gas turbine came to replace the steam engine in most ship applications. Trans-oceanic travel, transatlantic and transpacific, was a particularly important application, with steam powered Ocean liners replacing sailing ships, then culminating in the massive Superliners which included the . The event with the Titanic lead to the Maritime Distress Safety System. Maritime events of World War I At the start of the war, the German Empire had cruisers scattered across the globe. Some of them were subsequently used to attack Allied merchant shipping. The British Royal Navy systematically hunted them down, though not without some embarrassment from its inability to protect allied shipping. For example, the detached light cruiser , part of the East-Asia squadron stationed at Tsingtao, seized or destroyed 15 merchantmen, as well as sinking a Russian cruiser and a French destroyer. However, the bulk of the German East-Asia squadron – consisting of the armoured cruisers and , light cruisers and and two transport ships – did not have orders to raid shipping and was instead underway to Germany when it was lost at the Battle of the Falkland Islands in December 1914. Soon after the outbreak of hostilities, Britain initiated a naval blockade of Germany, preventing supplies from reaching its ports. The strategy proved effective, cutting off vital military and civilian supplies, although this blockade violated generally accepted international law codified by international agreements. A blockade of stationed ships within a three-mile (5 km) radius was considered legitimate, however Britain mined international waters to prevent any ships from entering entire sections of ocean, causing danger to even neutral ships. Though there was limited response to this tactic, some expected a better response for German's aim with its unrestricted submarine warfare. German U-boats attempted to cut the supply lines between North America and Britain. The nature of submarine warfare meant that attacks often came without warning, giving the crews of the merchant ships little hope of survival. After the infamous sinking of the passenger ship in 1915, Germany promised
