In 1912 a German Telefunken wireless transmitter was built in Sayville (now West Sayville) to broadcast to Germany. In 1915 the transmitter allegedly relayed a message from the German embassy to "get Lucy", referring to the RMS "Lusitania" which was sunk on May 15. Whether the signals coming from the transmitter in Sayville authorized the attack or not, they caused concern for the US government, which dispatched Marines to ensure that encrypted messages were not sent. The station was seized by the government outright after war was declared in 1917. President Woodrow Wilson sent a contingent of Marines to seize the wireless station, making it the first hostile action taken by the United States against Germany during World War I.
