Many of the unarmed ships were engaged in getting arms and explosives to England. As ships not carrying war materials were not "certified safe" all vessels were sunk to ensure the transport of such materials.This process is carried on today when hospitals and schools are routinely destroyed as possible "enemy headquarters" and wedding gatherings are shot up as potential "insurgent assemblies" by America and its allied in their Middle East.
The German government announced unrestricted submarine warfare against ANY ship sailing into Allied waters would be subject to surprise attack. Along with the German sabotage of Black Tom island powder magazine in 1916, the sinking of the Lusitania with American citizens onboard, and the Zimmerman telegram (German foreign secretary) that encouraged Mexico to ally with Germany and Mexico would win bad the former Mexican territory in the US South West, lead President Wilson to call for war. There were additional reasons, but I feel these were the Big Four.U Boats were causing havoc on the trade routes between the US and Europe by destroying merchant ships. One of the biggest factors was the sinking of the Ocean Liner "Lusitania" by German UBoats, of the 139 US Citizens on board 128 were killed. Also, when Germany began a Submarine Campaign against Britain President Wilson had previously stated he would hold Germany responsible if that were to occur.
items were in short supply for Britain because all their cargo ships bringing food and other things in from the US were torpeoded and sunk by the German UBoats
Uboats were made to attack and sink merchant ships carrying supplies to Great Britain. Germany knew if they managed to cut Britain's supplies off then they would be unable to continue the war. They did this by launching torpedos which blew holes in enemy ships under the waterline, causing them to take on water and sink. As the war progressed, more and more were built to combat military ships as well as merchant vessels. Hope this helps.
Much of the East coast was blacked out as Nazi Uboats were sinking shipping all the way from NY to FL. They also did some shelling with their small deck guns.
Hitler intended to cut the sea lines between the US and Europe by having an armada of ships block the shipping channels. Hitler tried everything possible to cut the sea lines.
a group of German uboats that hunted Allied and US ships
Yeah I actually think the lusitania was one of the first boats sunk from a Uboat
The Lusitania was a boat that sailed across the Atlantic Ocean from America to some other Allied Country in Europe. In the Atlantic Ocean the Central Powers (mainly Germany) had UBoats that sank a lot of ships travelling to and fro from the Allied forces. The Lusitainia was sunk on it's voyage to Europe.
The Allies sunk German Uboats. Uboat, not you-boat. Uboats stand for Unterseeboot - undersea boat.
The invention of radar helped the Allies to locate and sink the German U Boats.
Yes the Germans created uboats, they have had them since the dawn of time, litterally
The Germans then threatened to use only Uboats for war and blew up a few ships.

because of the alliances the US had made previous to the start of the war along with the threat of the German Uboats attacking US civilians and property.

The submarines attacked Pearl Harbor
No. It is an urban legend. They were seen by a shipyard worker but they never fired. It is understood the UBoats were doing reconnisance duties of the Eastern Coast of the USA. There have been accounts of people in Boston seeing them too.
