Once the U.S. was an active participant in the war, the vulnerability of Florida’s long coastline attracted German submarines, or U-boats, seeking to eliminate freighters who supported the Allies. Ships traveling in the Gulf Stream were closest to shore in Palm Beach County, increasing its attraction. Although newspapers would not risk informing the enemy by publishing current information about a torpedoed ship, coastal residents had front row seats to watch it burn. In response, many who spent the war at home took an active part in defending their shores and supporting visiting military personnel.
